The difference between them is slight. Primarily the white on the Barack Obama extend the length of the rhinophores. Unfortunately, these photos do not do it justice. I found it flying around in the water column and waved it down with my glove - [Bermudella pellucida](https://www.karollewall.com/bermudella-pellucida/) - [Some Pics From Kona, January 2020](https://www.karollewall.com/some-pics-from-kona-january-2020/) - Mahalo Bruce and Alan for this incredible experience!!

Its identification is ultimately to be determined. Closest we can come right now is a lighter version of Elysia lobata. - [Focussing on the small: Oct 15 - Nov 15, 2019](https://www.karollewall.com/focussing-on-the-small-oct-15-nov-15-2019/) - [Whale Watch, Hula Girl -- February 25th 2020](https://www.karollewall.com/whale-watch-hula-girl-february-25th-2020/) - [Black-tailed Deer and Great Blue Heron, Thieves Bay, Pender Island](https://www.karollewall.com/black-tailed-deer-and-great-blue-heron-thieves-bay-pender-island/) - Please enjoy these photos of an incredible inter-species encounter. As I was walking along the dock at Thieves Bay late in the afternoon, I spooked a Great Blue Heron who was hiding behind a boat. She took off and landed on the breakwater. What followed will be etched in my mind forever. The heron began - [Week II & III, Maui 2021](https://www.karollewall.com/week-ii-iii-maui-2021/) - The last 2 1/2 weeks have unveiled an incredible array of sea creaturea -- some entirely new to me, some "new to Hawaii" and some unidentified, new species. The highlights? Swimming with a graceful manta,seeing my first Smooth Sea Horse and Harlequin Shrimps. Who comes up with these designs? Two inches max, these Harlequins, these - [In the Rubble. Maui First Week, 2021](https://www.karollewall.com/in-the-rubble-maui-invertebrates-mostly-first-week-2021/) - I've spent the first few days on Maui exploring the rubble areas of North Kihei -- not areas that are particularly rich in vertebrates, but what they lack in fish they gift in beautiful and small crustaceans and sea slugs. Enjoy. Some of these little guys are no bigger than 6 mm.

Six weeks later the sea is still acting out. We woke to a tsunami warning this morning January 15, 2022. I have - [Snorkeling Peter Cove, 'S,dayes' (Pender Island), B.C.](https://www.karollewall.com/snorkeling-peter-cove-pender-island-b-c/) - Peter Cove S., 'S,dayes' (Pender Island). This was my first day in the water for some time and winter temperatures have set in for sure! It would be stretching it to say it was 8° C. Visibility wasn't as good as I'd expected - a little cloudy horizontally, but the skies were blue and the - [Random Photos of Pender](https://www.karollewall.com/random-photos-of-pender/) - [S'dayes (Pender Island) Dock Life](https://www.karollewall.com/sdayes-pender-island-dock-life/) - These photos primarily focus on the life that exists on a private dock on S'dayes (Pender Island). This is hopefully a plea to all dock owners -- scraping your docks and freeing them of those "pesky" sponges and tube worms, kills a number of incredible animals and plants who find their home on these relatively - [Boat Nook, Pender Island (S'dayes) Dec 1 2024](https://www.karollewall.com/boat-nook-pender-island-sdayes-dec-1-2024/) - A beautiful morning snorkeling in Boat Nook, S'dayes (Pender Island) with some of the Pender Penguins. Highlights were the first recorded sighting (for me and inaturalist) of a Pacific Sea Nettle and a "new to me" Cooper's Dorid (Aldisa Cooperi). - [Bay Pipefish, Syngnathus leptorhynchus](https://www.karollewall.com/bay-pipefish-syngnathus-leptorhynchus-2/) - These photos were taken in late May of 2020 while snorkeling in the shallows of Peter Cove, Pender Island -- a rare treat to see several Bay Pipefish, Syngnathus leptorhynchus engaging in a mating dance. At one point, a male and female pipefish exchange eggs-- the male being the one who will carry the embryos - [Lilies and Lily Pads II, Buck Lake, July 2022](https://www.karollewall.com/lilies-and-lily-pads-ii-buck-lake-july-2022/) - [Lilies and Lily Pads, Buck Lake July 2022](https://www.karollewall.com/lilies-and-lily-pads-buck-lake-july-2022/) - A fun photo shoot with somewhat cooperative subjects and ever-present antagonists: leeches, newts and giant water snails. Some acrobatics were required but it was such a joy to play in the warm(wish) water with colour and refractions, light and reflections. - [Redeye Medusa, Polyorchis penicillatus](https://www.karollewall.com/redeye-medusa-polyorchis-penicillatus/) - This jelly is a treat to see -- not only for its delicate structure but for its pulsing movement - [Cnidarians and Ctenophores, 2021](https://www.karollewall.com/cnidarians-and-ctenophores-2021/) - [Orange Peel Nudibranch, Acanthodoris lutea](https://www.karollewall.com/orange-peel-nudibranch-acanthodoris-lutea/) - The only photograph I have of an Acanthodoris lutea is of a juvenile -- extraordinarily tiny (8 mm?). It was found in the upper subtidal zone in an area of rock and sand substrate. Unfortunately, I assume it was a pulchra and did not get too fussy about taking photos. But at least the sighting - [Salish Sea Marine Life](https://www.karollewall.com/salish-sea-marine-life/) - Sorry if you arrived here and expected to go somewhere else -- lots of links through the menu, or click on the latest update to Nudibranchs of the Salish Sea below. http://www.karollewall.com/nudibranchs-of-the-salish-sea-4/ - [Snorkeling 'S,dayes' ( Pender Island), January 2021](https://www.karollewall.com/snorkeling-pender-island-january-2021/) - The water has been cold -- between 6 & 8° C (43 to 47° F) but the purchase of a Yazbek 7.5 mm open cell wetsuit has made a huge difference to my ability to stay in winter waters. Everyone always speaks of the beautiful clarity of the British Columbia ocean in the winter, but - [Bricky Bay, Pender Island -- March 11th, 2019](https://www.karollewall.com/bricky-bay-pender-island-march-10th-2019/) - [Most Recent Images: Galiano Island](https://www.karollewall.com/most-recent-images-galiano-island/) ## Pages - [Home](https://www.karollewall.com/) - [Eubranchulus rupium: (Green Balloon or Rocky Aeolid)](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/green-balloon-nudibranch-eubranchus-rupium/) - This aeolid nudibranch is so small it is virtually invisible. Most of the animals photographed here are between 3 and 5 mm. Their eggs will often stand out against the Obelia longissima hydroids they are laid upon (or close to). Look closely (perhaps with the macro lens of a camera) and you may see the - [Homely Aeolid, Eubranchus rustyus](https://www.karollewall.com/homely-aeolid-eubranchus-rustyus/) - This is another one of those tiny little nudibranchs that is usually overlooked. Like the Eubranchulus rupium, their eggs are often easier to spot than the animal itself. In the case of this animal (and there was only one on this Plumaria hydroid), it was the eggs that drew my attention, and that was only - [White-crusted Aeolid, Tenellia albocrusta](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/white-crusted-aeolid-trinchesia-albocrusta/) - This is another tiny aeolid that is virtually impossible to see hiding amidst the tiny hydroids it preys upon and seaweed it inhabits. It is often found close to the Eubranchus rupium, and I have mistaken the two on more than one occasion. Its notable feature is the white patch on its upper dorsum and - [Dryodora glandiformis](https://www.karollewall.com/10931-2/) - Return to Ctenophores This small (15? mm ) boreal species is more commonly seen further north than the Salish Sea, so this was a rare treat. According to Claudia Mills, this ctenophore has an unusual reproductive strategy. In response to the first photo below, she notes that "rows of eggs are visible in behind - [Branched Dendronotus, Dendronotus venustus](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/branched-dendronotus-dendronotus-venustus/) - When I first found these tiny dendronotus, I was certain they were Bushy-backed Dendronotus or Dendronotus frondosus, but the inaturalist community quickly corrected my error, pointing out that D. frondosis is a separate species, now limited to the Northern Atlantic. There seems to be so little information about this newly designated species that I - [Nudibranchs of the Salish Sea](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/) - This page provides links to pages about sea slugs who are "shell-less": those species which are generally referred to as Dorids, Dironas, Triophas, Aeolids, Dendroids and Melibe. I have purposely set species that are similar in shape, design and colour alongside one another, to make initial identification easier. Should the viewer be looking for members - [Brown-streaked Sapsucker, Stiliger fuscovittatus](https://www.karollewall.com/marine-life-of-the-salish-sea/sea-slugs-of-the-salish-sea-sea-hares-bubble-shells-etc/brown-streaked-sapsucker-stiliger-fuscovittatus/) - See detailed explanation below the images. This is a tiny little sapsucker that I mistook for an aeolid nudibranch, the Green Balloon Nudibranch or Eubranchus rupium. . . but sacoglossans (sapsuckers) are a whole different entity -- not nudibranchs at all, having no gills. And since this was the ONLY sapsucker I had come across - [Branched Sapsucker, Placida dendritica](https://www.karollewall.com/branched-sapsucker-placida-dendritica/) - Finally! 2026 turned out to be the year I finally found a couple of very young Placida dendritica. They've probably been staring me right in the face. I'd like to say I just learned to see, to look for the right algae in the right area, somewhat protected from the greater sea and huge surge. - [Olive's Sapsucker, Hermaea oliviae](https://www.karollewall.com/marine-life-of-the-salish-sea/sea-slugs-of-the-salish-sea-sea-hares-bubble-shells-etc/olive-sapsucker-hermaea-oliviae/) - This beautiful little sapsucker is rarely seen and it was certainly a surprise to find this tiny Hermae oliviae feeding on some red filamentous algae in the shallows. This particular animal has a full set of cerata, something that seems to be fairly rare among the specimens I've seen documented. They tend to autotomize their - [Sea Slugs of the Salish Sea: Sacoglossans, Sea Angels, Sea Hares, Bubble Shells, Headshield Slugs, Marine Snails, etc.](https://www.karollewall.com/marine-life-of-the-salish-sea/sea-slugs-of-the-salish-sea-sea-hares-bubble-shells-etc/) - This page is meant to be a quick reference for those looking to identify Salish Sea sea slugs and snails that do not fall into the larger category of nudibranch. Most have shells -- some visible and others cloaked in a mantle. The exception is the Sea Angel, which loses its shell within a few - [Umbrella Jelly, Eutonina indicans](https://www.karollewall.com/umbrella-jelly-eutonina-indicans/) - I always thought this little jelly was a rather boring, ubiquitous one until I had the opportunity of seeing one with a lovely lilac/burgundy tone up close! Wow. They are often found in large numbers, and I've actually seen the surface bubbling with them. Seeing an individual close up has changed my perspective! inaturalist offers - [Thick-horned Nudibranch (Northern Opalescent?) , Hermissenda Crassicornus](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/thick-horned-nudibranch-hermissenda-crassicornus/) - The Thick-horned Nudibranch was previously called the Opalescent Nudibranch, but recent taxonomic studies have set it apart from its southern cousin the Hermissenda opalescens. Many believe the common name "Thick-Horned" should be changed. Northern Opalescent Nudibranch seems far more appropriate!! These animals can be utterly ubiquitous in certain areas and rarely seen in others. The - [Blood-spot Aldisa, Aldisa sanguinea](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/blood-spot-aldisal-aldisa-sanguinea/) - It took a little time to identify the first individual, spotted in 2016, as it turned out to be an unusual range extension. The waters off the Pacific West Coast were warmer than usual between 2014 & 2017 and this Blood-spot Aldisa, usually found no further north than Oregon, was discovered off of British Columbia. - [Unidentified Discodorid Sp. 12](https://www.karollewall.com/unidentified-discodorid-sp-12/) - This is a sporadically common species, apparently, but Fall 2022 is the first time I have noticed them in over 12 years of looking for nudibranch species on Maui. I was fortunate to come across two very distinct looking individuals together -- one a cream white with bright green branchia and another a deeper brown - [Cnidaria: Jellies and Siphonophores of the Salish Sea](https://www.karollewall.com/marine-life-of-the-salish-sea/jellies-of-the-salish-sea-4/) - The jellies documented below, with the exception of Nanomia bijuga (a siphonophore) belong to the sub-class discomedusa or hydromedusa -- gelatinous animals with tentacles that are all too often referred to as "jellyfish." Though I have provided some anecdotal and descriptive information that should be helpful in identifying these more commonly seen species, there seems - [Ptychogena californica](https://www.karollewall.com/ptychogena-californica/) - This is a very rare and beautiful jelly to find in a shallow cove off of Pender Island, British Columbia. Or anywhere. They are considered a deep water species, found in the Eastern Pacific from California to British Columbia. Currently there are only two reports of this jelly on inaturalist, both found in the Salish - [Cigar Comb Jelly, Beroe Abyssicola](https://www.karollewall.com/marine-life-of-the-salish-sea/ctenophores-i-e-comb-jellies/cigar-comb-jelly-beroe-abyssicola-2/) - Return to Ctenophores The Cigar Comb Jelly is one of the most common comb jellies in the Salish Sea. A short walk along a dock in early May revealed over 50 individuals floating by in a period of 20 minutes. These jellies are voracious eaters and primarily feed on other cnidarians. In a couple - [Janna's Dorid,  Atalodoris jannae](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/jannas-dorid-knoutsodonta-jannae/) - This is one of the very many small white dorids found throughout the Salish Sea/Pacific Northwest. Fortunately it is a little easier to identify than some of the others. There is usually a brightish white bump behind its branchial gills, its mantle is covered in tubercles that vary from large white bumps to club-like and - [Orange-edged Sapsucking Slug, Thuridilla lineolata](https://www.karollewall.com/thuridilla-lineata/) - This seems to be a fairly common species in East Sumbawa, Indonesia as I found at least 25 of these animals while snorkelling in relatively shallow waters. Like most of the sacoglossans in this area, they tend to love broken or dying coral covered in algae. Most of these animals were at least 20 mm, - [Thuridilla ratna](https://www.karollewall.com/thuridilla-gracilis/) - When I first found this sacoglossan in amongst some broken coral and algae covered rocks, I couldn't determine whether it was a Thuridilla gracilis, a T. bayeri or a T. ratna. According to the experts on inaturalist, Thuridilla ratna it is. All three share a similar colour pattern with a dark brownish/black background, fine white - [Elysia thompsoni](https://www.karollewall.com/elysia-thompsoni/) - Elysia thompsoni appears to be a very rare find in Indonesia. This sighting is the only one recorded on inaturalist as of December 2025. It is fairly common, however, in Australia -- particularly in the Northwest. Elysia Thompsoni is a small sacoglossan, reaching about a maximum size of 10 mm in length and it is - [Rose-pink Cuthona, Cuthona divae](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/rose-pink-cuthona-cuthona-divae/) - This tiny nudibranch is often mistaken for one of the "red-gilled" nudibranchs, the Himatina triophina or the Coryphella pseudoverrucosa, but its distinguishing features are its near-transparent rhinophores and its bright-white tipped cerata. They feed on the very bright salmon-pink hydroid and their eggs are much differently shaped than those of the triophina or pseudoverrucosa. Their - [Cooper's Aldisa, Aldisa Cooperi](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/coopers-aldisa-aldisa-cooper/) - This is an unusual little dorid for a snorkeller to find but both of the animals documented here were found in the upper intertidal during extremely high fall tides. They can range in colour from a very light yellow to a dark orange and can be easily mistaken for the Aldisa sanguinea or Blood Spot - [Melicertum octocostatum (Yellow Octo Jelly?)](https://www.karollewall.com/melicertum-octocostatum-yellow-octo-jelly/) - I have no idea whether there is a common name for this jelly, but it definitely has eight radial arms, so . . .I also cannot find much information about this jelly. It's tiny, it's fairly rarely found in the Salish Sea and pure pleasure to behold. - [Dinner Plate Jelly, Solmissus sp.](https://www.karollewall.com/dinner-plate-jelly-solmissus-sp/) - These jellies are commonly referred to as Dinner Plate Jellies because their platter-like bell can reach an overall size of 20 cm or nearly 8". They are unusual among medusas in that they actively search for their prey, rather than relying on the fortune of having copepods, other cnidarians and ctenophores and/or salps cross their - [Red Dendrodoris, Dendrodoris Sp #1](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/dendrodoris-sp-1/) - My snorkeling buddy spotted this rare nudibranch in about 1 metre or 3 ft of water along a rocky, algae and sand covered reef in West Maui. Needless to say, we were pleasantly surprised to see such a large (3 inch) colourful nudibranch cruising about in the brilliant morning sun. The only other red nudibranch, - [Dendrodoris tuberculosa](https://www.karollewall.com/dendrodoris-tuberculosa/) - This large nudibranch species is easily mistaken for a Dendrodoris carbunculosa and I must admit to doing so the first time I found one of these animals. The difference can be subtle, especially if you have no access to the underside of the animal. The D. carbunculosa lacks markings whereas the D. turberculosa has obvious - [White Spotted Nudibranch, Goniobranchus albopunctatus](https://www.karollewall.com/white-spotted-nudibranch-goniobranchus-albopunctatus/) - The Goniobranchus albopunctatus or White Spotted Nudibranch is not commonly seen by snorkelers or divers. The individuals photographed below differ significantly in colour, and their bodies can indeed vary from yellowish to reddish -- the lighter ones sometimes being mistaken initially as Imperial Nudibranchs, and the darker ones as Red Both individuals documenter here were - [Red-Spotted Nudibranch, Goniobranchus sp. #1](https://www.karollewall.com/red-spotted-goniobranchus-sp-1/) - Since I have never personally had the pleasure of seeing one of these nudibranchs, I will leave the details and the more varied photos to Keoki Stender and the Sea Slug Forum. This particular individual was found floating in the water column, which is probably the only reason my snorkel buddy saw it. They are - [Pitted Nudibranch, Aldisa pikokai](https://www.karollewall.com/aldisa-pikokai/) - This is a hard nudibranch to spot, as it is often on its host sponge (or very close by) making it virtually disappear into the orange sponge-covered landscape. Their relatively small size and three small crater-like depressions mid-notum don’t help. These two animals were found in about 2 metres of water on an orange sponge-covered - [Sclerodoris Sp.#1](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/sclerodoris-sp-1/) - This nudibranch is a member of the Discodorididae family. It looks so much like the red sponge it feeds upon that, unless it moves, it is extremely difficult to notice. Its body is covered in blotches of white and cream (and often sand) with a central crater that makes it appear even more sponge-like The - [Speckled Platydoris, Platydoris formosa](https://www.karollewall.com/speckled-platydoris-formosa/) - I love this nudibranch! Between February 2019 and January 2023 I have come across three animals, all at varying stages of development and all solitary individuals. The first sighting was of a juvenile (approximately 40 mm). The second was around 60 mm (just over 2") and the third was fully mature -- at least 150mm - [Clumpy Nudibranch (Asteronotus cespitosus)](https://www.karollewall.com/nudibranchs-sea-hares-of-maui/) - This large clumpy nudibranch definitely suits its common name. It is fairly round and dotted with clumps or creamy lumps that are divided by a noticable bumpy central ridge. Its rhinophores are club-like with noticeable bent "clumps" on top. The body varies in colour from brownish/grey/tan to a light yellow. If you're lucky, you'll find - [Water Jelly, Aequorea victoria](https://www.karollewall.com/water-jelly-aequorea-victoria/) - Description below images. Return to Jellies of the Salish Sea The Aequoriea victoria (commonly referred to as the Crystal Jelly or Water Jelly) is a relatively large jelly found throughout the inner coastal waters of the Pacific Northwest, but it is often overlooked due to its transparency. Fortunately, they stand out against the thick kelp - [Yellow-edged Cadlina, C. klasmalmbergi or Cadlina sylviaearleae](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/yellow-edged-cadlina-c-klasmalmbergi-or-cadlina-sylviaearleae/) - There are now a number of newly described species that used to fall under the umbrella category of "Yellow-edged Cadlina" or Cadlina luteomarginata. Recent research has identified several new species: Cadlina klasmalmbergi, Cadlina sylviaearleae and Cadlina jannanicolsae. The most notable difference between the C. luteomarginata, C. klasmalmbergi, C. sylviaearleae is that the latter two have - [Modest Cadlina, Cadlina Modesta](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/modest-cadlina-cadlina-modesta/) - At first glance the Modest Cadlina resembles the Yellow-Edged Cadlina, but it lacks the obvious yellow marginal rim of the latter. Both feed on sponges and both tend to have rhinophores and gills that have a yellowish-brown tinge. The Modesta cadlina is rarely spotted as it is fairly small (to 35 mm or just over - [Giant White Dorid, Doris odhneri](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/giant-white-dorid-doris-odhneri/) - This is one of the largest nudibranchs on the West Coast, getting up to 20 cm or 8". They are rarely seen by snorkelers or tide-poolers as they prefer the subtidal zone. This individual was found approximately 10 ft below the lowest tide mark and was at least 7" or 17.5 cm. They are usually - [Common Sea Hare, Dolabrifera dolabrifera](https://www.karollewall.com/common-sea-hare-dolabrifera-dolabrifera-2/) - The Dolabrifera dolabrifera, is a fairly common sea hare (hence its common name). It can often be found in tide pools, old fish ponds, shallow intertidal and subtidal zones. They are excellent at camouflage and will often lie flat in the curves of rocks and algae, making themselves near invisible to the naked eye. Many - [Eyed Sea Hare, Aplysia oculifera](https://www.karollewall.com/eyed-sea-hare-aplysia-oculifera/) - Eyed Sea Hares are rarely seen, but when they are it is not uncommon to find them in abundance, hiding in the algae and sea weed or under rocks and in walled crevices. They tend to blend in well with their surrounding. Disturb one, and you may find yourself covered in a dark purple/pink mucous - [Taylor's Sea Hare, Eelgrass Sea Hare ( Phyllaplysia taylori)](https://www.karollewall.com/taylors-sea-hare-phyllaplysia-zostericola/) - This sea hare is just about impossible to see when it is snuggled into the branches of eelgrass or zostera. Its camouflage is obvious and it is most commonly known as the Eelgrass Sea Hare. It grazes on diatomes and other epiphytes found on the green leaves and lays its tiny eggs in a zigzag - [Albatross Aglaja, Melanochlamys diomedea](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/albatross-aglaja-melanochlamys-diomedea/) - If it weren't for the expertise of scientists who devote their lives to studying head shield slugs, I'm sure I'd still be baffled regarding an identification of this species. See the Sea Slug Forum for how involved the discussion of these animals can be. Apparently, these are quite common and numerous but easily overlooked. Their - [White Berthella, Boreoberthella chacei](https://www.karollewall.com/california-berthella-berthella-californica/) - This snow white side-gilled slug is a pleasure to find. At first glance it appears to be more like a cadlina, but on close examination it becomes clear that this animal lacks the gills typical of dorids. They have an oral veil and a white-margin running around the mantle and the foot, but their rhinophores - [Red Dorid, Rostanga pulchra](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/red-dorid-rostanga-pulchra/) - This tiny dorid is fairly common (once you figure out where to find them). They tend to feed on red encrusting sponges, so look for those in the intertidal, highsubtidal zones and then look for what may appear to be mere blobs. Most often these individuals have their gills and rhinophores withdrawn, making them even - [Lobed Sap-sucking Slug, Elysia lobata](https://www.karollewall.com/elysia-lobata/) - Return to Sacoglossia When this tiny 12 mm (1/2") sapsucker was first photographed we were unsure of its identification. It moved a bit like a bulbaeolidia alba, clicking its paradoda as it moved, but looked like a lighter version of the Elysia lobata that is described on Sea Slugs of Hawaii. So we contacted - [Hairy Elysia, Elysia tomentosa](https://www.karollewall.com/hairy-elysia-elysia-tomentosa/) - The Hairy Elysia or Elysia tomentosa is another cryptic sea slug -- almost impossible to see as they generally take on the colour of the algae on which they feed. Some are a deep emerald green, some a dusty brown. Some have very noticeable flesh coloured margins; others have margins that are barely visible. - [Neal's Elysia, Elysia Nealae](https://www.karollewall.com/neals-elysia-elysia-nealae/) - Though relatively common, Elysia nealae is not an easy sacogglosan to find unless you stick to the shallows (just a couple of metres) and scour the algae found on rocky bottoms and protected reef areas like fish ponds and accretion platforms. These animals were found in North Kihei, Maui and were between 18 and 25 - [Iridescent Elysia, Elysia sp. #9](https://www.karollewall.com/elysia-sp-9/) - This is probably one of the most beautiful sea slugs I have ever seen. Unfortunately, it was slightly damaged, so a photo of a completely unblemished individual was impossible. Still . . . the colours and the excitement of finding it was probably up there with finding my first nudibranch. This Elysia is definitely not - [Neon Slug, Thuridilla neona](https://www.karollewall.com/neon-slug-thuridilla-neona/) - Wow! This slug is tiny, bright, irridescent and such a wonderful creature to find. Apparently, aggregations are relatively common but I have only ever come across one individual in a protected rocky area of a traditional fishpond. This little one was barely 1/2 inch. Found in less than 4 ft of water. Check out - [Rusty Elysia, Elysia rufescens](https://www.karollewall.com/rusty-elysia-elysia-rufescens/) - The Rusty Elysia is often found alongside or close to the Ornate Elysia and, at first, I found them quite difficult to tell apart. Both have sendentary and migratory forms and orange margins. Both have chimneys (or not, depending on their form). The individuals documented in the gallery below were all found in less than - [Orange Gumdrop Side-gilled Slug, Berthellina delicata](https://www.karollewall.com/orange-gumdrop-side-gilled-slug-berthellina-delicata/) - Yep, this side-gilled slug looks like a yellow or orange gumdrop -- albeit a good sized one. The ones with bumps on their overtly gelatinous bodies make them look a lot like sea lemons or oranges. I have seen them as large as 2 1/4" or 60 mm. These seem to be relatively common -- - [Spotted Leopard Dorid, Diaulula odonoghuei](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/spotted-leopard-dorid-diaulula-odonoghuei/) - This is a cute dorid, one that is a joy to watch as it moves across its sponge prey. Apparently, northern animals (such as those found in the Salish Sea) differ significantly from their southern counterparts and those that tend to be found closer to the wilder coast of Vancouver Island. The Diaulula odonoghuei has - [Thuridilla cf. vatae](https://www.karollewall.com/thuridilla-cf-vatae/) - This particular sapsucker is an extremely rare sighting on Maui, and perhaps anywhere. As Cory Pittman of Sea Slugs of Hawaii points out, Thuridilla vatae is relatively common throughout the Indo-western Pacific, but these individuals shows clear differences in their markings (see Sea Slug Forum for more photos and discussion). We call it the Taradilla - [Swollen Bubble Shell, Hydatina amplustre](https://www.karollewall.com/swollen-bubble-shell-hydatina-amplustre/) - Finding the precious, fragile tiny coral banded shells of these bubble shells is a treat in itself. But to find a living, moving creature -- WoW! Not only are they nocturnal, they love to bury themselves in sand that is similar in colour to their shells. Like the Wavy Bubble Shell, they are usually found - [Thuridilla carlsoni](https://www.karollewall.com/thuridilla-carlsoni/) - Cryptic is how Cory Pittman and Pauline Fiene describe the Thuridilla carlsoni in Sea Slugs of Hawaii. I couldn't agree more. One of these individuals was found in a tide pool in about 2" or 5 cms of water, hiding in the algae. It blended in so well with its surroundings that it wasn't - [Sea Angels, Gymnosomata (Naked Sea Butterfly, Clione limacina)](https://www.karollewall.com/sea-angels-gymnosomata/) - This is not a cnidarian, though it is often mistaken for one. These beautifully transparent, planktonic animals are actually members of the order opistobranch and have much more in common with nudibranchs than hydrozoans. They are technically sea slugs and anyone who has the gift of spotting one will likely never forget how resilient they - [Ornate Sapsuckers, Elysia marginata](https://www.karollewall.com/ornate-sapsuckers-elysia-marginata/) - At first I found these Elysia marginata extremely difficult to tell apart from the Elysia rufescens (or Rusty Elysia). Apparently, this is because they are extremely variable and come in sedentary and migratory forms and often share the same territory as the rufescens. Seek out Cory Pittman and Pauline Fiene's Sea Slugs of Hawaii site - [Heath's Dorid, Geitodoris heathi](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/heaths-dorid-geitodoris-heathi/) - The Heath's Dorid seems to be a little more difficult to find than the other two "sea lemons" -- Monterey Dorid or Noble Sea Lemon. It is generally smaller, has a more semi-circular opening around the gills and smaller tubercles. Not sure why, but these critters always seem to be a bit flat and ragged - [Marine Life of the Salish Sea](https://www.karollewall.com/marine-life-of-the-salish-sea/) - Over time these pages will reflect most of the marine life that is visible to shallow free divers, snorkelers and tide-poolers. The majority of these images were taken at low tide in the Southern Gulf islands of the Salish Sea -- the area settlers once described as the Georgia Strait and Juan de Fuca/San Juan - [Flatworms of Maui, Hawaii: Phylum Platyhelminthes](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/flatworms-of-maui-hawaii-phylum-platyhelminthes/) - It seems that not much is really known about Hawaii's flatworms, perhaps because they are rarely seen and few scientists seem to specialize in this phylum. With Cory Pittman's help, John Hoover has compiled the most comprehensive Hawaii Flatworm site and it is an exceptional collection. Over the past few years, our snorkelling - [Cockerell's Dorid (Limacia cockerelli)](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/cockerells-dorid-limacia-cockerelli/) - When I first posted images of this dorid to social media, I got numerous responses: "Oh, it looks like a dessert. . . . "a birthday cake with two candles on it" . . . "a bunny rabbit" . . . "I just want to pet his stomach or head or whatever that big white - [Tailed Jelly, Nanomia septata -- a Colonial Siphonophore](https://www.karollewall.com/tailed-jelly-nanomia-bijuga/) - I can't imagine anyone seeing this strange looking creature for the first time without thinking, "what the heck is that?" With its bizzare looking red-beaconed, gas-filled float on top of a "head" made up of a colony of genetically identical zooids called nectophores and another collection of buoyant zooids that trails behind, it is indeed - [Sapsuckers, Plakobranchidae (Elysias, Thuridillas, Polybranchia)](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/sapsuckers-plakobranchidae-elysias-thuridillas-polybranchia/) - These animals come by their common name "sapsuckers" legitimately. Nearly all of them use their radular tooth (they have more but they store used ones??) to puncture the cells of algae and suck out their contents -- rather vampire-like, but innocent, and totally different in that many are diurnal, and most are herbivores. Some are - [Canadian Comb Jelly (Bolinopsis microptera)](https://www.karollewall.com/common-northern-comb-jelly-bolinopsis-infundibulum/) - Return to Ctenophores This ctenophore can get fairly large -- up to 15 cm or 6". Like all comb jellies it vibrates its fine cilia in order to move up, down and sideways in the water column, often creating a rainbow-like effect. This particular ctenophore takes on a number of different shapes, from butterfly-like - [Orange Peel Nudibranch, Tochuina gigantea](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/orange-peel-nudibranch-tochuina-gigantea/) - The only photographs I have of Tochuina gigantea are atypical. They are usually more orange than yellow and their frilly white margins and white-tipped rhinophores are tell-tale (not yet developed in the juvenile pictured here). The first image, taken by a fellow snorkeller/free diver is much more yellow than the average "orange peel." Nudibranchs often - [Murphydoris cf. cobbi](https://www.karollewall.com/murphydoris-cf-cobbi/) - This is an incredibly tiny nudibranch (3-4 mm max), so tiny that I thought it was more likely that I was taking a photo of a shell . . . until it moved and disappeared quickly into a hole. There are a few clearer photos of this on the Sea Slugs of Hawaii site. Cory - [Red-fingered Coryphella (Coryphella longicaudata)](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/red-fingered-coryphella-coryphella-pseudoverrucosa/) - This is just a quick update. Will explain further when I have a moment. The "Red-fingered Coryphella" has gone through another taxon change and is now the Coryphella longicaudata. For the novice, Coryphella longicaudatta is just about impossible to distinguish from the Coryphella trophina. There have been several taxon changes in the Flabellinidae family (of - [Siladen, Indonesia: Snorkeling Bunaken Marine Park](https://www.karollewall.com/snorkeling-indonesia-siladen-bunaken-marine-park/) - In October, 2017 I had the pleasure of staying at Siladen Resort & Spa in Bunaken Marine Park. It is primarily a dive resort, but they go out of their way to accommodate snorkelers. Here's a tiny sampling of the fish I was able to see while snorkeling or shallow free diving. Some were taken - [Bubble Shells, Head Shield Slugs, Order Cephalaspidea](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/bubble-shells-head-shield-slugs-order-cephalaspidea/) - Our group of snorkelers, researchers, reef cleaners and turtle rescuers has not found too many of these beautiful sea slugs. Perhaps this is because we have only been searching for the ones that stand out on relatively shallow reefs and in tide pools. According to Sea Slugs of Hawaii, there are plenty of drab, well-camouflaged - [Eelgrass Palio, Palio zosterae](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/eelgrass-palio-palio-zosterae/) - I'm not sure how common this tiny tiny nudibranch is, but I do know it fits extremely well into its surroundings. I found the first one while I was kayaking on some flattened eelgrass beds back in 2009. It was no more than 8mm and barely visible to the naked eye -- they blend in - [Egg Yolk Jelly, Phacellophora camtschatica](https://www.karollewall.com/egg-yolk-jelly-phacellophora-camtschatica/) - This is one of the most striking and appropriately named cnidarians of the Pacific Northwest/Salish Sea. Over the past few years I have come across juveniles as small as 50mm (2") across the bell to animals as large as 60 cm (2 ft) across with copious tentacles as long as 3 metres (10 ft). -- - [Predaceous Aeolid (Coryphella trophina)](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/red-gilled-nudibranch-himatina-trophina/) - Telling Predaceous Aeolid (Coryphella trophina) from the Red-fingered (Coryphella verrucosa) apart is just about impossible without close examination. They appear to be almost identical. They are found feeding in the same territory and their primary prey (hydroids) appears to be the same as well. Add to this the fact that both have undergone numerous taxon - [Lamellaria](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/lamellaria/) - Lamellaria are technically NOT sea slugs--rather they are snails, but they are so commonly mistaken as sea slugs, that I have included them here for the time being. This is a quick photo reference. For more information on these animals, please see the Velutinidae section of Sea Slugs of Hawaii. Lamellaria Sp. #7 - [Side-gilled Slugs or Pleurobranchidae](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/side-gilled-slugs-or-pleurobranchidae/) - Side-gilled slugs are often hard to notice . They tend to be nocturnal and hide under rocks, in the sand or in side crevices during the day. Some of them also look a LOT like sponges, lie flat and inconspicuous until disturbed, and generally have a rubbery texture. Their gills are, as their name suggests, - [Nudibranchs of Hawaii](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/) - This page provides links to more detailed pages on individual nudibranchs that are found in 25 ft or less (7.5 metres) of water. Unlike more scientific sites, I have organized these in a way that may be more novice friendly. When I was first learning about sea slugs I would look for colours and shape - [Sea Slugs of Maui: Nudibranchs, Side-gilled Slugs, Sapsuckers, Bubbleshells, Etc.](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/) - Welcome to the Sea Slugs of Maui Site -- a site originally set up to help a group of fellow snorkelers, reef cleaners, hawksbill searchers, researchers and turtle disentanglers identify the nudibranchs we were finding as we dove to pick up weights and line and various bits of trash along the ocean floor. Finding so - [Fibropapillomatosis in Green Sea Turtles](https://www.karollewall.com/fibropapillomatosis-in-green-sea-turtles/) - Fibropapillomatosis is a virus that primarily affects green sea turtles. It is often a fatal disease, with many turtles dying from organ failure, an inability to feed themselves and/or complete blindness. It is believed that nitrogen run-off from agriculture, golf courses and homes has contributed significantly to this disease. Snorkelers off of Maui's coasts will inevitably - [Some Current Research Related to Fibropapillomatosis](https://www.karollewall.com/some-current-research-related-to-fibropapillomatosis/) - NOAA has an excellent article on frequently asked questions re the Fibropapilomatosis virus that was updated in 2025. For some time, scientists have been investigating the possible reasons why some areas have higher incidents of turtles afflicted with fibropapillomatosis than others. It is becoming more and more evident that hgher incidents occur in areas with - [Fibropapillomatosis Virus and other Injuries](https://www.karollewall.com/green-sea-turtles-with-fibropapillomatosis-virus-and-other-injuries/) - Fibropapillomatosis is a virus that primarily affects green sea turtles. It is often a fatal disease, with many turtles dying from organ failure, an inability to feed themselves and/or complete blindness. It is believed that nitrogen run-off from agriculture, golf course and homes has contributed significantly to this disease. Snorkelers off of Maui's coasts will - [Avaldesia tamatoa](https://www.karollewall.com/thordisa-albomacula/) - All of the Alvadesia tamatoa documented here were found in (or just outside) a shallow, old traditional fishpond in North Kihei in less than 2 meters of water. It appeared to be just another sponge or tunicate, but upon the slightest touch, its rhinophores popped up and its strange trumpet-like branchial gill became quite prominent. - [Spiny Hairy Horned Dorid, Acanthodoris atrogriseata](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/spiny-hairy-dorid-acanthodoris-pilosa/) - I have given this little dorid the common name of "Spiny Hairy Horned Dorid," in order to ease identification for those in the Pacific Northwest. Most people have described this species as Acanthodoris pilosa, but it has been recently redescribed as Acanthodoris atrogriseata and is a different species altogether. This is a very small acanthodoris - [Sunflower Star, Pycnopodia helianthoides](https://www.karollewall.com/marine-life-of-the-salish-sea/sea-stars-of-the-salish-sea/sunflower-star-pycnopodia-helianthoides/) - The Sunflower Star is one of the most voracious sea stars in the world, and also one of the largest. I personally have seen individuals that were almost a metre across. Up until the 2013, the first year people started noting the affects of Sea Star Wasting disease, I would find huge animals dying on - [Sea Stars of the Salish Sea](https://www.karollewall.com/marine-life-of-the-salish-sea/sea-stars-of-the-salish-sea/) - There are over 30 species of Sea Stars to be discovered in the Pacific Northwest. Divers have access to most of them, whereas those snorkeling, free diving and tide-pooling will be limited to the upper sub-tidal and intertidal zones. Most of these photos were taken in the Salish Sea in relatively calm areas at very - [Ctenophores ( i.e., Comb Jellies)](https://www.karollewall.com/marine-life-of-the-salish-sea/ctenophores-i-e-comb-jellies/) - Ctenophores, more commonly called comb jellies, do not belong to the same phylum as your typical pulsating jelly. Ctenophores propel themselves through the water by moving tiny comb-like structures called ctenes. All comb jellies in the Salish Sea/Pacific Northwest have eight rows of ctenes that light up in rainbow-like colours as they vibrate, but some - [Stearn's Ear Shell, Marsenina stearnsii](https://www.karollewall.com/stearns-ear-shell-marsenina-stearnsii/) - This unusual Velutinidae is extraordinarily difficult to see as it is small (less than 2 cm) and it looks like the white ascidian sponge or bryzoan it usually feeds on. The first time I noticed one I thought I had somehow knocked off a barnacle, but it continued to move quickly across the substrate and - [Sclerodoris sp. #2](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/sclerodoris-sp-2/) - This Sclerodoris is fairly rare, or simply not seen because of its incredible ability to mimic a sponge. In fact, when I first encountered one, I wasn't entirely sure I was photographing a nudibranch. Its branchia could just as easily have been a feather duster worm poking through the cavity of a sponge. It was - [Spanish Dancer, Hexabranchus sandwichensis](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/spanish-dancer-hexabranchus-sandwichensis/) - The OTHER Spanish Dancer! This is actually the "Spanish Dancer" that is most commonly seen by snorkelers. It was originally described as Hexabranchus pulchellus, but has since been distinguished as one of the two Hawaiian hexabranchus species. Although they are primarily nocturnal, these animals were found in broad daylight on Maui's South and North Shores - [Spanish Dancer, Hexabranchus aureomarginatus](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/spanish-dancer/) - This Spanish Dancer, or Hexabranchus aureomarginatus, is the largest nudibranch found in Hawaiian waters. It can reach up to 200mm or approx 9". When threatened, or knocked off its reef "mooring" it will dance through the water column. Its dancing movements combined with its red, yellow and white colour, frilled branchial gills and unfurling margin - [Black Dendrodoris, Dendrodoris nigra](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/black-dendrodoris-dendrodoris-nigra/) - The first time I encountered these nudibranchs I confused them with some very dark Common Sea Hares. Turns out it is not uncommon to find them hiding in similar crevices in rocky, protected areas. The white tips on their rhinophores are a bit of a giveaway -- though apparently, the darker version of the Red - [Doris sp. 1?](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/doris-sp-1/) - This tiny doris (8-10 mm) was found on a shelf of grey sponge in - [Doris Pecten](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/doris-pecten-2/) - Although this nudibranch is fairly common it is usually overlooked due to its diminutive size and the fact that it is often found on a similarly coloured food sponge. All animals photographed here were under 15 mm (5/8") and found in wave washed lagoons or fishponds from La Perouse Bay to North Kihei, Maui. The - [Bermudella pellucida](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/bermudella-pellucida/) - Although this little Goniodorididae nudibranch is fairly common in certain areas of Ma'alaea Harbour Maui, it was still exciting to find one a little further south, caught up in some fishing line that resembled its prey (or other way around)? Though most of the zooids of the Amathia bryozoan on which they prey have been - [Butterflyfish of Maui, Hawaii (Family Chaetodontidae -- Lauhau in Hawaiian)](https://www.karollewall.com/butterflyfish-of-maui-hawaii-family-chaetodontidae-lauhau-in-hawaiian/) - Although there are 25 species of Butterflyfish on Maui, this album reflects my experience as a snorkeler/underwater photographer on Maui. Some of these fish are common enough to be seen at most snorkel sites, and a few are rarely seen. They are among the most beautiful fish and certainly one of the most recognizable. A - [Leaf Sheep, Costasiella kuroshimae](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/sapsuckers-plakobranchidae-elysias-thuridillas-polybranchia/leaf-sheep-costasiella-kuroshimae/) - The Leaf Sheep Sea Slug. The infamous solar powered sea slug. Shaun the Sheep. . Yes this is the same species that has made sea slugs all over the world famously loveable and cute. In Hawaii, it doesn't seem to get the bright pink tips and luscious green cerata of those found in Indonesia and - [Barack Obama Slug, Placida Barackobamai](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/sapsuckers-plakobranchidae-elysias-thuridillas-polybranchia/barack-obama-slug-placida-barackobamai/) - This little member of the Limapontiidae family (order Sacoglossa) has a few look-a-likes. Placida Kevinleei can also be found on Hawaii, but it has less pronounced white lines on its rhinophores and tends to be smaller. The two animals documented here, however, appeared to be no more than a couple of black dots on their - [Sea Hares ( order: Aplysiidae)](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/sea-hares-order-aplysiidae/) - The six species of Sea Hares documented here were found on Maui, either in tide pools, shallow lagoons, protected coves or old traditional Hawaiian fish ponds -- all in less than 2 metres of water. Until one knows what to look for they can go unnoticed, often hiding in the algae they eat, under rocks, - [Striped Nudibranch, Armina californica](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/striped-nudibranch-armina-californica/) - The Striped Nudibranch is a rare sighting for anyone snorkeling or free diving above 30ft subtidal, as its primary prey in the Pacific Northwest is an octo-coral, the Sea Pen. I was quite surprised to discover these in the upper subtidal. I was turning over kelp leaves on a murky no-viz day when I noticed - [Lion Head or Hooded Nudibranch, Melibe leonina](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/lion-head-or-hooded-nudibranch-melibe-leonina/) - This nudibranch is fascinating to watch, particularly if it has been threatened off its perch on the eelgrass or kelp beds. It will dance, moving itself back and forth and up and down the water column, sometimes just resting as the tide carries it from one home to another. These animals are so translucent that - [White-Spotted Dendronotus, Dendronotus albopunctatus](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/white-spotted-dendronotus-dendronotus-albopunctatus/) - This is a beautiful dendronotus that is rarely rarely seen -- so rare that inaturalist.org has only one other observation, documented in 1986 in Oregon. At first glance it appears to be a Bushy Back Nudibranch, but if one looks closely it has a white margin on its large foot, is generally larger (up to - [Rainbow Nudibranch, Dendronotus iris](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/rainbow-nudibranch-dendronotus-iris/) - This large nudibranch (sometimes referred to as the Giant Nudibranch) is absolutely stunning to watch as it swims through the water column. Many of the photos below are simply "creative" images of a species that has me mesmerized. I did watch as one of them swam right into a balloon and as another swam with - [Red Dendronotid (Dendronotus rufus)](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/red-dendronotid-dendronotus-rufus/) - This is a fairly large nudibranch and quite beautiful to watch as it moves. I have seen individuals as large as 20 cm, but apparently they can get to 27 cm or 270 mm or 11 inches!! Though they are primarily subtidal, I have found them on the underside of leaf kelp and on docks, - [Three-lined Aeolid, Coryphella trilineata](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/three-lined-aeolid-coryphella-trilineata/) - This beautiful Three-lined Aeolid is apparently fairly abundant along the west coast -- from Baja California, Mexico to Alaska, but it doesn't seem to be a nudibranch that many snorkelers and shallow free divers see in the Salish Sea. The Red-fingered Coryphella is much more common and perhaps the similarities between the two mean some - [cf. Price's Aeolid, Apata cf. pricei](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/cf-prices-aeolid-apata-cf-pricei/) - This little nudibranch had me baffled for a while. A Hermissenda crassicornis? Nope. A Chocolate Aeolid? Nope. Apparently it's a member of the Apata species, and was considered a Price's Aeolid (Apata pricei) up until a couple of years ago when it was relegated to the cf. category (meaning, more research is needed . - [Common Grey Slug, Aeolidia Papillosa](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/common-grey-slug-aeolidia-papillosa/) - Yep, this greyish slug looks rather drab -- and indeed it is often overlooked, even when found in large numbers. It is "common" throughout the world and at times can be utterly prolific in certain areas. Apparently, it can take on darker colours, and even a reddish colour, depending on its food source -- which - [Shaggy-mouse Nudibranch, Aeolidia loui](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/shaggy-mouse-nudibranch-aeolidia-loui/) - This nudibranch, upon first glance, looks pretty much identical to another, the Aeolidia papillosa. If I hadn't thrown the image up on inaturalist.org, I would still be thinking this individual was a Common Grey and not a Shaggy-mouse. The difference lies in the tiny bumps found on the rhinophores of the Aeolidia loui. So look - [White-and-Orange-Tipped Nudibranch, Antiopella fusca](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/white-and-orange-tipped-nudibranch-antiopella-fusca/) - Previously known as the Janolus fuscus, this nudibranch is often confused with the more common Thick-horned Nudibranch (Hermissenda crassicornis). The primary difference is that the cerata are present in front of the rhinophores. I often find these nudibranchs feeding on bryzoans or floating in on a piece of loose kelp or sargassum. - [Golden or Orange Dirona, Dirona pellucida](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/golden-or-orange-dirona-dirona-pellucida/) - This nudibranch is quite simply stunning -- all photos below are of one smallish individual (4 cm) that I found in the low intertidal/subtidal boundary moving its way through some kelp. At first I thought this was an orange version of the very similar Dirona albolineata (common names: Frosted, Alabaster and White-lined). But the lack - [Sea Clown Triopha, Triopha catalinae or Triopha modesta](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/sea-clown-triopha-triopha-catalinae/) - Due to a recent 2020 taxonomic study, the Sea Clown Triopha has now been divided into two distinct species: the Triopha catalinae and the Triopha modesta. Most of the species documented here are Triopha modesta, which is now considered to be a trans-Pacific species, found primarily along the coast of British Columbia and Southern Alaska - [Cryptic Bryozoan Nudibranch, Steinberg's Nudibranch, Corambe steinbergae](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/cryptic-nudibranch-steinbergs-nudibranch-corambe-steinbergae/) - This nudibranch is indeed cryptic. To say that they blend in with their host/prey would be an understatement. It took me over 15 years of searching kelp fronds and kelp leaves to find the Corambe steinbergae documented here. By early summer the Lacy Crust Bryozoan, Membranipora villosa can cover the underside of leaf kelp almost - [Ridge-tailed Dorid, Diaphorodoris lirulatocauda](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/ridge-tailed-dorid-diaphorodoris-lirulatocauda/) - Ok. Tiny, tiny, tiny. Maybe 8 mm? The microscopic setting on the camera was the only saving grace when it came to documenting these little white balls of sluggy fluff. For identification, I had to turn to the inaturalist community, and as usual they came through. Apparently, there are numerous teensy white dorid species in - [Chan's Dorid, Hallaxa chani](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/chans-dorid-hallaxa-chani/) - It's hard to know how common this nudibranch is as it is incredibly cryptic. When I came across one in late June of 2024, it was my first in nearly 20 years of looking for sea slugs in the intertidal and upper sub-tidal zone. I actually thought it was just another sponge on the side - [Yellow-edged Cadlina, Cadlina Jannanicholsae](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/yellow-edged-cadlina-cadlina-jannanicholsae/) - The Cadlina jannanicholsae is a newly described species that further complicates identifying 'Yellow-edged Cadlinas." In the past few years several new Cadlinas have been added to the "Cadlina luteomarginata" complex and photographs are often inadequate in determining the exact species. Janna's Cadlina does have noticeably larger flower-like tubercles, a substantive yellow margin and lacks the - [Barnacle Nudibranch, Onchidoris bilamellata](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/barnacle-nudibranch-onchidoris-bilamellata/) - These little dorids are often found on docks or pilings and under rocks, so they are easily accessible to the shallow snorkeler or tide-pooler. Almost invisible, they generally blend right into their surroundings as they munch away on the acorn barnacles they feed upon. Sharp radula are used use to break through the barnacle crust, - [Fuzzy Onchidoris, Ochidoris muricata](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/fuzzy-onchidoris-ochidoris-muricata/) - Another teensy white dorid! This one was a mere 1/2 inch -- or 13 mm and it was hiding in a hole beneath a ledge. At first I thought it was another Janna's Dorid (much more common), but it turns out "the white gland at the base of the gills looks triangular (as found in - [Hudson's Dorid, Acanthodoris hudsoni](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/hudsons-dorid-acanthodoris-hudsoni/) - This member of the Acanthodoris family is a fairly common sighting in the Pacific Northwest. It is relatively visible as it can get up to 5 cm or 2 inches and its somewhat translucent/whitish body seems to reflect light in a way that is quite striking. Like the Nanaimo Horned Dorid, it has very obvious, - [Nanaimo Horned Dorid, Acanthodoris nanaimoensis](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/nanaimo-horned-dorid-acanthodoris-nanaimoensis/) - This member of the doridina sub-order resembles several other nudibranchs that are commonly found in the Salish Sea. However, its maroon/brown tipped rhinophores and gills set it apart from the Yellow-edged Cadlina, Cadlina modesta, and Acanthodoris Hudsoni. It is not uncommon to come across several of these in one snorkel/free dive in the Pender Islands. - [Yellow-edged Cadlina, Cadlina luteomarginata](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/cadlina-luteomarginata/) - This beautiful little member of the Chromodorididae family resembles a number of other nudibranchs found off of British Columbia's West Coast --many of which are referred to generally as "Yellow-edged Cadlinas." It is most often mistaken for the Hudson's Horned Dorid (Acanthodoris hudsoni), as it too has a yellow margin and tubercles with buttery yellow - [Monterey Dorid, Doris montereyensis](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/monterey-dorid-doris-montereyensis/) - This bright yellow, brown spotted dorid is probably the most common nudibranch seen by PNW snorkelers and tide-poolers alike. It can get fairly large (up to 15 cm) and it's not unusual to find them on docks and pilings, or even squished into pockets of water under rock ledges above the low tide line. The - [Noble Sea Lemon, Peltodoris nobilis](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/noble-sea-lemon-peltodoris-nobilis/) - The Noble Sea Lemon gets its name both from its obvious similarity to the fruit and the fact that, when removed from the water, it smells like citrus. At first sight it can be mistaken for the Monterey Dorid or Heath's Dorid. Look for a full white branchial plumage and brown markings that do not - [Ctenophores (Comb Jellies)](https://www.karollewall.com/marine-life-of-the-salish-sea/ctenophores-comb-jellies/) - The comb jellies fall into different . . . - [Alabaster Nudibranch, Dirona albolineata](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/alabaster-nudibranch-dirona-albolineata-2/) - This stunning nudibranch is a favourite of photographers, not only because of its ghostly, transparent qualities, but because its shape is ever changing and its cerata catch the light in ways few other species do. It can be quite a common sight in the later winter months. I have seen as many as 20 gathered - [Baeolidia moebii](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/baeolidia-moebii/) - This species seems to be relatively common in shallow waters among rocks, in crevices and occasionally cruising across the algae. As a snorkeler, I see them often in less than 3 metres (10 ft) of water, especially if there are sea anemones in the area. They vary greatly in colouring from a light brownish tint - [Babakina indopacifica](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/babakina-indopacifica/) - The first time I found Babakina indopacifica I thought it was the ever-present, rather common, and comparatively drab Bulbaeolidia alba, but was perplexed by the seeming separate movement of the prominent orange spot. Turns out it was a set of rather tall orangeish-red rhinophores that are not only disproportionate but fused together at the bottom! - [Aplysia elongata Sea Hare](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/sea-hares-order-aplysiidae/aplysia-elongata-sea-hare/) - I have never seen this little sea hare myself, but my wonderful colleagues and friends have -- all in a shallow protected area on the North Shore, Maui. They appear to come in numerous beautiful colours and are a little less than 2 inches. I completely bow to Cory Pittman and Pauline Fienes on this - [Aliculastrum debile](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/bubble-shells-head-shield-slugs-order-cephalaspidea/aliculastrum-debile/) - This is a rather drab looking headshield slug, but one that is rarely seen as it prefers to bury itself in sand and is nocturnal. I only noticed it when it went flying through the water column after a goatfish disturbed the sand. A close examination reveals spiral markings on its shell and some white - [Alabaster Nudibranch, Dirona albolineata](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/alabaster-nudibranch-dirona-albolineata-3/) - The Dirona albolineata has numerous common names, all of which make complete sense: Alabaster Nudibranch, Frosted Nudibranch, White-lined Dirona, Chalk-lined Dirona. All of the ones I have seen are either white or a yellowish-orange colour, but they do come in a lovely lilac/purple, lined in white. If you find a dirona of a dark orange - [Ancula gibbosa, Humped Ancula Sea Slug](https://www.karollewall.com/marine-life-of-the-salish-sea/nudibranchs-of-the-salish-sea-4/ancula-gibbosa-humped-ancula-sea-slug/) - The Ancula gibbosa is a tiny nudibranch (max 33 mm) that has eluded me for at least fifteen years. This one was actually found by accident. While swimming through some eelgrass, some algae got caught on my arm. When I went to pull it off, I noticed a tiny tiny white critter moving. I only - [Cross Jelly, Mitrocoma cellularia](https://www.karollewall.com/cross-jelly-mitrocoma-cellularia/) - Back to Jellies of the Salish Sea This is a fairly common jelly and it can sometimes be seen in large congregations. Its transparency is perhaps its best defense -- often they make themselves noticeable when one sees the surface of the sea pulsating or an anemone happens to attach itself to its bell. - [Chubs of Hawaii](https://www.karollewall.com/229-2/) - Hawai'i is home to a number of different chubs, and it is often difficult for the novice snorkeler to tell them apart. Well, it's often difficult for the marine biologist to tell them apart. I have done my best and I'm happy to discuss potential changes with anyone. The Hawaiian Fishes site provides a good - [Saddleback Butterflyfish, Chaetodon ephippium](https://www.karollewall.com/saddleback-butterflyfish-chaetodon-ephippium/) - These striking fish are relatively common in the Makena to La Perouse area of Maui, but fairly rare in other parts of Maui and the Hawaiian Islands. It's not uncommon to see a pair darting about under ledges or nipping away at the edges of branching corals and filamentous algae. They are also known to - [About Karolle Wall](https://www.karollewall.com/about-karolle-wall/) - After retiring from her position as an Associate Professor in the Department of Critical Studies, Emily Carr University of Art & Design, Karolle chose to focus on her passion for the oceans, animals, and environmental education. For 12 years Karolle split her time between Maui and the Gulf Islands of British Columbia. She now calls - [Sea Slugs of West Komodo](https://www.karollewall.com/sea-slugs-of-west-komodo/) - This is a test. - [Home 2](https://www.karollewall.com/home-2/) - [Basic Slideshow](https://www.karollewall.com/basic-slideshow/) - [test](https://www.karollewall.com/test-4/) - [Test](https://www.karollewall.com/test-3/) - [Leaf Sheep, Costasiella fridae](https://www.karollewall.com/leaf-sheep-costasiella-fridae/) - This is a tiny Sacoglossid (maximum size is 12 mm 1/2") and it is often lumped with the many costasiellas that are referred to as "Leaf Sheep" or "Shaun the Sheeps." These little ones were photographed on their food prey, the invasive algae Avrainvillea amadelpha by snorkeler and marine photographer D. McLeish in approximately 6 metres - [Catablema vesicarium ssp. nodulosum](https://www.karollewall.com/catablema-vesicarium-ssp-nodulosum/) - This little jelly is a relatively common sight in early Spring, though it can easily be mistaken for the Neoturris breviconus or other "tall-top jellies" with large orangeish blobs for stomachs/gonads. The Catablema multicirratum is much larger and has far more tentacles and the newly described Leuckartiara longicalcar has noticeable long spurs extending up beyond - [Lewis's Moonsnail, Neverita lewisii](https://www.karollewall.com/lewiss-moonsnail-neverita-lewisii/) - Seeing a Lewis's Moonsnail out of its shell, laying its egg casing or actually plowing through the sand is an unforgettable experience. These animals are large! They lay foot-wide egg casings that are reminiscent of beautiful grey pieces of pottery -- a mix of egg, sand and mucous. I actually blame Lewis's Moonsnail for - [Bicolor Nudibranch, Samla bicolor](https://www.karollewall.com/bicolor-nudibranch-samla-bicolor/) - I rarely snorkel on S. Maui without finding one of these tiny nudibranchs. They are diurnal and are often seen crawling along the edge or on top of algae laden rocks Most of these individuals were found in less than 2 metres of water and were between 10 and 20 mm in size. There - [Acanthozoon cf. fuscobulbosum](https://www.karollewall.com/acanthozoon-cf-fuscobulbosum/) - This is another one of those flatworms that has many "look-a-likes" and without a confirmation from Rene Ong, a polyclad flatworm specialist, I would still be lumping this under the broader category of Acanthozoon. This was a fast moving flatworm, found in less than 2 metres of water outside a fishpond in North Kihei, Maui. - [Gymnodoris sp. 12](https://www.karollewall.com/gymnodoris-sp-12/) - This is a tiny gymnodoris, maybe 8 mm max and it appears to enjoy eating the eggs of other gymnodoris. I've caught one in the act twice now! Apparently, I first documented this species in January of 2020 -- see photo of miniscule gymnodoris in same basic vicinity as much larger Gymnodoris okinawae. Unbeknownst - [Orange & Black Margin Flatworm, Pseudobiceros 13](https://www.karollewall.com/orange-black-margin-flatworm-pseudobiceros-13/) - I am fairly certain this worm is a Pseudobiceros 13, but I have to admit I have made up the name Orange & Black Margin Flatworm. I should add spotted to that name. It is very similar to the Glorious Flatworm (Pseudobiceros c.f gloriosus) found on John Hoover's Flatworms of Hawaii site. Unlike the gloriosus, - [Unknown Euryleptid or Pseudocerotid](https://www.karollewall.com/unknown-flatworm/) - I have no idea what this flatworm is. I happened to be diving down to retrieve some marine debris and noticed this on the way up under a cave ledge. I took a quick photograph but it was in an awkward and dangerous spot and I couldn't return safely in the surge. Apologies for the - [cf. Euryleptid 2](https://www.karollewall.com/cf-euryleptid-2/) - This is a species that initially baffled me and some of the experts, but I have seen enough of them close up now to be pretty sure they are the ones that John Hoover has on his site listed as cf. Euryleptid 2. Fellow snorkellers and I found several in the rocks outside of Ko'ie'ie - [Pseudobiceros 18](https://www.karollewall.com/pseudobiceros-18/) - This is a beautiful little flatworm that is apparently quite rare, or at least rarely seen. It has a beautiful yellow and white rim that frames a white-splotched black centre. This particular teensy animal (maybe 12 mm?) was found in a rubble strewn area off of Nth Kihei, Maui in approximately 2 metres of water. - [Euryleptid Sp?](https://www.karollewall.com/euryleptid-sp-2/) - This tiny Euryleptid is a newly found species on Maui and it does not appear to be accounted for in any of the CD's or books recently published on Flatworms of the Indo-Pacific. Its prominent pseudotentacles suggest it is of the Eurylipedae family. It was a relatively small flatworm, perhaps 18 mm and appeared to - [Carminodoris bifurcata](https://www.karollewall.com/carmondoris-bifurcata/) - Carminodoris bifurcata is probably more common than it seems, but it is easily overlooked as it closely resembles a sponge or tunicate. These four animals were all found in a rubble-laden intertidal surge zone in Nth Kihei, Maui during the late fall and early winter months and over a period of a few years. The - [Bermudella pellucida](https://www.karollewall.com/sea-slugs-of-maui-nudibranchs-side-gilled-slugs-sapsuckers-bubbleshells-etc/nudibranchs-of-hawaii/bermudella-pellucida/bermudella-pellucida/) - Although this little Goniodorididae nudibranch is fairly common in certain areas of Ma'alaea Harbour Maui, it was still exciting to find one a little further south, caught up in some fishing line that resembled its prey (or other way around)? Though most of the zooids of the Amathia bryozoan on which they prey have been - [Pikachu Nudibranch, Thecacera pacifica](https://www.karollewall.com/pikachu-nudibranch-thecacera-pacifica/) - I have a lot to say about this nudibranch, especially that it is always a thrill to find this strange, bright, bizarre looking creature. All animals in this gallery were found in less than 20 ft (6 metres) of water in North Kihei, Ma'alaea Bay area. Until I get a moment to elaborate, please - [Eared or Giant Sea Hare, Dolabella auricularia](https://www.karollewall.com/eared-or-giant-sea-hare-dolabella-auricularia/) - Growing up to 12" or 300mm, the Dolabella auricularia is one of the largest slugs in Hawaii (the Aplysia Argus can grow to a similar size). On the reef it is easily mistaken for a large sponge. Its most prominent feature is its blunt, cut-off posterior. It is often found on beaches or floating across - [Indian Nudibranch, Caloria indica](https://www.karollewall.com/indian-nudibranch-caloria-indica/) - The Caloria indica is a fairly common but striking species of the Facelinidae family. We have found it crawling across the sand in water less than a metre deep, against a protected rock wall and in 20 ft of water on a algae covered exposed shelf. Divers can find it to 60 metres. It is - [Kevin Lee's Placida, Placida kevinleei](https://www.karollewall.com/kevin-lees-placida-placida-kevinleei/) - These tiny little sacoglossans are easily mistaken for the Placida Barackobamai. The difference between them is slight. Primarily the white on the Barack Obama extend the length of the rhinophores. Unfortunately, these photos do not do it justice. I found it flying around in the water column and waved it down with my glove - [Kevin Lee's Placida, Placida Kevinleei](https://www.karollewall.com/kevin-lee-nudibranch-placida-kevinleei/) - These tiny little sacoglossans are easily mistaken for the Placida Barackobamai. The difference between them is slight. Primarily the white on the Barack Obama extend the length of the rhinophores. Unfortunately, these photos do not do it justice. I found it flying around in the water column and waved it down with my glove - [test](https://www.karollewall.com/test-2/) - test - [Vayssierea felis](https://www.karollewall.com/vayssierea-felis/) - I originally mistook this 1-2mm (yes, no bigger than that) orange nudibranch for a newborn gymnodoris of some sort, but when I looked more closely at the photos later I realized it had no gills and its rhinophores had a distinct shape in relationship to its body. This was a Vayssierea felis! This is - [Oval-shaped Gooseberry, Euplokamis dunlapae](https://www.karollewall.com/oval-shaped-gooseberry-euplokamis-dunlapae/) - Return to Ctenophores This species can initially be mistaken for the more common Pacific Sea Goooseberry (Pleurobrachia bachei) or the less common Cydippida sp. Those who are more familiar with "sea walnuts" and "gooseberry" comb jellies will notice this species has branched tentacles that immediately standout. What appear to be small pinkish coloured - [Egg-eating Nudibranch, Favorinus japonicus](https://www.karollewall.com/egg-eating-nudibranch-favorinus-japonicus-2/) - This is a relatively common nudibranch, but it is often overlooked due to its small size (up to 17mm) and the fact that it does an excellent job of blending into its background. Look for them hiding in the midst of their prey -- the eggs of other sea slugs. They take on the colour - [Ercolania sp. #7](https://www.karollewall.com/ercolania-sp-7/) - This is another tiny sacoglossan that blends in extremely well with its food source, making it almost impossible to see. A member of the Limapontiidae family meaning it is closely related to Placida barackobamae, and the costaciellas (leaf sheep). These are extremely tiny sea slugs (to 6mm). One individual below was found making its way - [Red Sausage Jelly, Euphysa spp.#](https://www.karollewall.com/red-sausage-jelly-euphysa-spp/) - Red Sausage Jellies are a curious bunch and up for debate and further research, hence the broad identification: Euphysa spp.#. A close look at these photos will reveal jellies with longer tentacles, shorter stumpy tentacles and even three tentacles. These are likely all different species but at this point their individual taxonomic categories are - [Cymbal Bubble Shell, Lamprohaminoea cymbalum](https://www.karollewall.com/cymbal-bubble-shell/) - This has to be one of the prettiest little gastropods on earth, or at least in the Indo-Pacific/Hawaiian and Christmas Islands where it is found, or maybe just in South Kihei. I mean, who gets to be lime/blue green with orange and white markings? I didn't have the opportunity of actually seeing one until the - [Bulla peasiana](https://www.karollewall.com/bulla-peasiana/) - Bulla piasiana is one of two species of Bullidae found in Hawaii. They are primarily nocturnal so it was a surprise to notice it feeding mid-day. However, it is doubtful I would have noticed its shell poking through the algae had my attention not been drawn to a diurnal Elysia ornatus feeding in the same - [Blob Top Jelly. Neoturris breviconis](https://www.karollewall.com/blob-top-jelly-neoturris-breviconis/) - There are years when this jelly seems to bloom and 2020/21 were two of those years. After several years of occasional sightings, I found myself swimming amongst hundreds in several different shallow coves and bays off the Southern Gulf Islands. The Spring and early summer brought them into the eelgrass beds and broad leaf kelp - [Tall Top or Long Spur Jelly, Leuckartiara longicalcar](https://www.karollewall.com/tall-top-jelly-leuckartiara-longicalcar/) - This is a recently described species that has long been thrown into the general category of "Tall-top jellies." There is an undeniable similarity to the Catablema vesicarium ssp. nodulosum, and other Leukartiara species, however there are some notable differences. C.E. Mills explains that the name longicalcar refers to the "long "spurs" that run a couple - [Ercolano sp. #7](https://www.karollewall.com/ercolano-sp-7/) - This is another tiny sacoglossan that belongs to the same family as the Costesiellas (Sheep) and Barack Obama - [Unidentified Euryleptid, Cycloporus?](https://www.karollewall.com/unidentified-euryleptid-cycloporus/) - This pair of Euryleptids was found under a flat rock in a surge zone along a fishpond wall in North Kihei, Maui in about 4 ft of water. So far they remain undentified, but Cory Pittman has suggested it is really similar to a Cycloporus found in New Caledonia and documented on inaturalist. https://www.inaturalist.org/observations/116230169. Its - [Pseudobiceros Sp. 5, Kikokiko](https://www.karollewall.com/pseudobiceros-sp-5-keokiko/) - This relatively large (40 -50 mm?) Pseudobiceros 5 was discovered by a fellow snorkeller, Allan B. It was just cruising across the sand in a few feet of water -- a rather rare occurrence. The photos of it taken on a rock are a result of moving it to a safer place -- out of - [Tritoniopsis sp. #1](https://www.karollewall.com/tritoniopsis-sp-1/) - This is a very rare sighting in shallow water and our group spotted two separate individuals on two separate days in less than 1 metre (3 ft o water). It was in an area of abundant blue octocoral, one of its food sources. Look for a teensy (18 mm max) white spot on a rock - [Polygon Pleurobranch, Pleurobranchus cf. peronii](https://www.karollewall.com/polygon-pleurobranch-pleurobranchus-cf-peronii/) - Description below Side=gilled Sea Slugs The polygon shaped pattern on these side-gilled slugs, and their striking rose/pink/magenta and sometimes gold colouring makes them a treat to find. The three individuals documented here were between 2 and 3" (50 mm to 75mm) and found in lagoons or fishponds in the North Kihei and Makena area of - [Porites Nudibranch, Tenellia lugubris](https://www.karollewall.com/porites-nudibranch-tenellia-lugubris/) - The only way I have ever been able to find this nudibranch is via its eggs. They lay stunning white, lacy, looping eggs that flare out from the centre and are often clustered. Their colour varies according to their food source, and can be anywhere from a dull brown/grey to brownish/orange to bright yellow. Look - [Pink Polyclad Flatworm, Unknown sp. (Euryleptid?)](https://www.karollewall.com/pink-polyclad-flatworm-unknown-sp-euryleptid/) - This unusual flatworm was found under a rock in North Kihei in an area of rubble, broken coral and plenty of sponge and tunicates. There were three small flatworms, all looking very much like a compound tunicate or unusual sponge. This flatworm is not found in Cannon and Newman's CD or in the Polyclad Flatworms - [Spurilla braziliana, Brazilian Aeolid](https://www.karollewall.com/spurilla-braziliana-brazilian-aeolid/) - The Spurilla braziliana is a rare find for a snorkeler or tidepooler on Maui, even though they are known to prefer shallow rocky habitats. When I first came across this rather large aeolid (approximately 30 mm or over an inch), I assumed it was ai, which is much more common. Its rhinophores, however, were perfoliate - [Lamellaria Sp. # 7](https://www.karollewall.com/lamellaria-sp-7/) - This little Lamellaria (approximately 20 mm) was found in less than 2 metres of water in a murky, mud covered, broken coral and rubble zone in North Kihei, Maui. This is an area where flooding washed tons and tons of toxic soil into the ocean during the winters of 2021-2023. It's amazing anything is surviving - [Bulaceros newcannorum](https://www.karollewall.com/bulaceros-newcannorum/) - This, apparently, is a flatworm that is rarely seen in Hawaii and its presence was even doubted until a recent sighting. It could be that this worm hides out in places that tend to be out of most diver's comfort (i.e., the shallow shallows) as I have come across a number of these worms and - [Costasiella Sp. #1](https://www.karollewall.com/costasiella-sp-1/) - These tiny Costasiella Sp. 1 were found grazing on some mudleaf or Avrainvillea amadelpha alongside a few Costasiella kuroshimae. One of them was notably larger than the C. kuroshimae -- likely 4-5 mm. Imagine an animal less than 1/4 of an inch, in a sandy surge zone on a piece of algae covered in sand - [Elysia pusilla](https://www.karollewall.com/elysia-pusilla/) - This is apparently a common species, but it is rarely seen. I certainly would not have found it if I hadn't been pulling fishing line that put me within inches of some Caulerpa racemosa (Rough Sea Grapes) on top of a lobe coral. Given its host I was pretty certain that I had found a - [Joubin's Sea Slug, Pelagella joubini](https://www.karollewall.com/joubins-nudibranch-goniodoris-joubini/) - This is apparently another relatively common nudibranch that is almost impossible to see. Their diminutive size (6- 7 mm) and bland colour enables them to hide rather well in their habitat of sponge and algae, rocky rubble, bryozoans and ascidians. Look closely and these brown and creamy-white Pelagellas are rather beautiful. Their mantle is framed - [Favorinus Sp. #1](https://www.karollewall.com/favorinus-sp-1/) - This is a rather innocuous and tiny nudibranch that can easily be overlooked or assumed to be the much more common white version of the Favorinus japonicus. The nudibranch documented here was only about 6- 8 mm and it wasn't until I could look at the images on the computer that I could make out - [Spanish Dancer, Hexabranchus sandwichensis](https://www.karollewall.com/hexabranchus-pulchellus/) - The OTHER Spanish Dancer! This is actually the "Spanish Dancer" that is most commonly seen by snorkelers. It was originally described as Hexabranchus pulchellus, but has since been distinguished as one of the two Hawaiian hexabranchus species. Although they are primarily nocturnal, these animals were found in broad daylight on Maui's South and North Shores - [Thuridilla Sp. #3](https://www.karollewall.com/thuridilla-sp-3/) - This little Sacoglossid is very easily recognized by the reddish-orange tipped tentacles and very obvious orangeish, white and black spots that create a kind of saddle-back appearance to the parodia. According to the Sea Slugs of Hawaii site, Thuridilla sp. # 3 is fairly common, but in over ten years of searching I have only - [Dendrodoris denisoni or Dendrodoris krusensternii](https://www.karollewall.com/dendrodoris-denisoni-2/) - I'm not sure if the Dendrodoris krusensternii is relatively rare or just hard to see. It tends to blend in very well with its surroundings and does a great job of burying itself in the sponge upon which it feeds. There is an area in North Kihei, Maui where I would say they are fairly - [Pseudocerotid F?](https://www.karollewall.com/pseudocerotid-f/) - This seems to be a fairly rare flatworm in Hawaii. Rebecca Bicker found a similar worm in relatively close proximity in July of 22 and it is documented on John Hoover's Flatworms of Hawaii site. Found in Nth Kihei in less than 2 metres of water. Approximately 25 mm. - [Melibe Sp. #1](https://www.karollewall.com/melibe-sp-1/) - Since this is the first recorded sighting of this Melibe in Hawaii, there is little known about it except for what this author and photographer has to say and some important elaborations made by Cory Pittman on Sea Slugs of Hawaii. I found this animal in less than a metre of water in a wave-washed - [Spotted Aglaga, Aglaja ocelligera](https://www.karollewall.com/spotted-aglaga-aglaja-ocelligera/) - In the waters of the Salish Sea, this headshield slug seems to be a little less common than the Blister Glassy Bubble. Upon initial sighting it can appear very similar to the darker version of the Hamaena vesicula, but its shell is usually covered by large outer flaps, and its head has very distiguishable white - [Blister Glassy Bubble, Haminoea vesicula](https://www.karollewall.com/blister-glassy-bubble-haminoea-vesicula/) - This little bubble shell can be dark or light, its eggs white or yellow (the latter being more common). They can be so prolific in the Spring/Summer that eelgrass beds can be covered in thousands of them, their eggs noticeable on nearly every leaf. Its shell is quite fragile and it often goes by the - [Stalked Jelly, Haliclystus sanjuanensis (nomen nudum)](https://www.karollewall.com/stalked-jelly-haliclystus-sanjuanensis/) - These stunning images of Haliclystus sanjuanensis were taken by Katherine Panfilova while she was snorkelling in an area off of West Sooke, British Columbia. Like most members of the order, Stauromedusae, H. sanjuanensis is quite small (4 cm max). They are a shallow dwelling creature and, consequently, one that snorkelers should have the opportunity to - [Root Branching Jelly, Cladonema californicum](https://www.karollewall.com/root-branching-jelly-cladonema-californicum/) - Root Branching Jelly, Cladonema californicum is a relatively "new" jelly -- recently described. The jellies photographed here were found on the underside of thick beds of leaf kelp in a shallow bay on Pender Island. They were so tiny that it was their simple jumping movement that alerted me enough to be able to see - [Euselenops luniceps](https://www.karollewall.com/euselenops-luniceps/) - Description below Return to Side-gilled Slugs This unusual and rather large (up to 75 mm) pleurobrancomorph is rarely seen in Hawaii. Many a diver or snorkeler has likely passed right over their posterior siphon and rhinophores sticking out of the sand. The odd fortunate ocean goer will get to see these sea slugs up in - [Prosthiostomum cf. trilineatum](https://www.karollewall.com/prosthiostomum-cf-trilineatum/) - This little flatworm was found inside a dead Black-lipped Pearl Oyster shell. While examining the bryozoan, algae, sponge and ascidians within, I noticed the worm make an appearance and quickly move to the outside of the shell. This particular animal was approximately 40 mm (they can reach 60 mm or over 2 inches). It stretched - [Red Dwarf Flatworm, Pseudoceros rubronanus](https://www.karollewall.com/red-dwarf-flatworm-pseudoceros-rubronanus/) - This tiny, but beautiful, flatworm (15 -20 mm) was found in a most unlikely place: in terrible, surgey conditions, in less than 1 metre of water on what appeared to be a battered, dead piece of coral swirling around in brown/foamy soup. The striking fuchsia colour drew enough attention that I turned my swim around, - [Boninia sp. ?](https://www.karollewall.com/boninia-sp/) - This little flatworm (30 mm max) was found in about 3 metres (10 ft) of water in the surge zone at Five Graves, Makena, Maui. At present, I can find no reference to previous sightings in Hawaii, but in their book "Marine Flatworms, The World of Polyclads” Newman and Cannon identify a very similar one - [cf. Acotylean 11](https://www.karollewall.com/acotylean-11/) - This is another rarely seen flatworm and quite beautiful one at that. It was just over 35mm and was found in the intertidal lagoons of Makena Landing, Maui. We're not certain that this is an Acotylean 11, hence the tentative title, suggesting a similarity between this worm and one that is rarely seen in Australia - [Acotylean A](https://www.karollewall.com/acotylean-a/) - This is a smallish flatworm (25 mm or 1 inch) that somewhat resembles cf. Prosthiostomid 3 at first glance, but it is not quite as elongated and it is noticeably thicker and fleshier. Acotylean A has fairly conspicuous, but small, nuchal tentacles just in front of its dark brown midline stripe. This stripe can be - [Cowries and Trivia](https://www.karollewall.com/cowries-and-trivia/) - lblbllshal - [Pseudocerotid sp??](https://www.karollewall.com/pseudocerotid-sp/) - This beautiful worm was found in a lagoon at Hekili Pt, Maui in less than 2 metres of water (4 ft). At first I thought it was a Pseudocerotid J, but it lacks the tell-tale patch at the back. It was also quite a bit bigger (40 mm) than any Pseudocerotid J I have seen. - [Mourgona Sp. #4](https://www.karollewall.com/mourgona-sp-4/) - This is yet another sea slug that looks like a tiny piece of algae on a rock, but on close inspection is quite stunning. Complete with lilac edging, orange, black and white spots and nearly transparent cerata, this little Mourgona demands a microscopic examination -- especially when compared to Mourgona sp. #1. Unlike #1, it - [Mourgona Sp. #1](https://www.karollewall.com/mourgona-sp-1/) - I'm not certain whether the unusual SW winter swells and storms of 2021/2022 have contributed to an abundance of this species in certain areas, or whether upturned stones and broken dead coral have exposed this relatively uncommon species in unusual numbers, but these 15-25 mm animals were found in relative abundance off of Olowalu, Maui - [Spotted Swallowtail Sea Slug, Chelidonura alisonae](https://www.karollewall.com/spotted-swallowtail-sea-slug-chelidonura-alisonae/) - The Spotted Swallowtail Sea Slug is even smaller than the Blue Swallowtail Slug, but it is easily confused at first. The bright orange bar of the Blue Swallowtail is replaced with two bright blue spots corralled by orange lines that generally run for a good length of the mantle. Their undersides are marked in an - [Batwing Sea Slug, Sagaminopteron Psychedelicum](https://www.karollewall.com/batwing-sea-slug-sagaminopteron-psychedelicum/) - This is a very tiny, very beautiful headshield sea slug that appears to be quite rare. Though our group of snorkelers and reef cleaners cover this area of North Kihei and Ma'alaea Bay fairly often, we have only come across this animal a few times. In all cases it was found in less than 10 - [Goniodoris sp. 1](https://www.karollewall.com/goniodoris-sp-1/) - This may be the tiniest nudibranch I have ever photographed. It stood out on a rock in an area of rubble due to its extreme cream and white colouring and the fact that it moved slightly. It was only the camera lens and microscopic setting that confirmed it was a goniodoris. How all these minute - [Elysia degeneri](https://www.karollewall.com/elysia-degeneri/) - Return to Sacoglossans At first sight, this Elysia might be confused with the Thuridilla Carlsoni, but if it unfolds its lobes just a little bit a bright orange inner line lies just beneath its margin. In the younger animal documented on this page, this orange line is quite obvious. 2020 is the first year we - [Elegant Sapsucker, Cyerce elegans](https://www.karollewall.com/cyerce-elegans/) - This stunning sapsucking sea slug is a very rare sight for snorkelers as it is most commonly found in Halimeda beds at depths of 10 metres or more. These individuals were found at the edge of a rock near a shallow Halimeda bed in Ma'alaea Bay, Maui. Conditions were turbulent and there were bits of - [Caliphylla Sp. #1](https://www.karollewall.com/caliphylla-sp-1/) - This is a difficult species to find, especially on Maui. Not only are they considered rare, but their camouflage ability is superb. Their cerata, while folded in a resting state, will unfurl into a leaf-like pattern almost identical to the bryopsis it feeds upon. The individual photographed here was found in less than 3 metres - [Acotylean I](https://www.karollewall.com/acotylean-i/) - There is some discussion as to whether this is the same flatworm as the one on John Hoover's flatworm site, identified as Acotylean I. The animal I found has a more beige tone to it and appears to be a little "fuzzier" but the eye spots between the tentacles and small white marks match the - [Acotylean I](https://www.karollewall.com/acotylean-1/) - This appears to be the second one of these beige/grey flatworms to be documented in Hawaii. - [Jorunna Alisonae](https://www.karollewall.com/jorunna-alisonae/) - This is a fairly common species, but I was only blessed with a sighting in the fall of 2022. Perhaps I have mistaken it in the past for the Discodoris lilacina as they are quite similar at first glance. This particular individual was quite small (10 mm) and was found in a rocky, surge zone - [Cacao Aeolid, Anteaeolidiella cacaotica](https://www.karollewall.com/cacao-aeolid-anteaeolidiella-cacaotica/) - The latin name for this tiny aeolid is so long and difficult to pronounce that I am bestowing Cacao on it as a common name -- not that it resembles chocolate in any way I can determine. It is a light salmon pink/orange colour with white tips to their cephalic tentacles and rhiniophores. Though the - [FInelined Flatworm, Pseudocerotid E.](https://www.karollewall.com/finelined-flatworm-pseudocerotid-e/) - These flatworms are tiny and quite honestly I thought it was a tiny chiton the first time I saw one -- until it moved ever so slightly. In all three sightings, these flatworms were found wandering about during the day on some algae or rocks in the North Kihei and Makena Landing areas of Maui - [Unidentified Flatworm Sp?](https://www.karollewall.com/unidentified-flatworm-sp/) - This tiny orange flatworm was found in less than 2 metres of water on a sponge shelf. It darted into the orange/yellow sponge so quickly that I couldn't get a good photo of it. It's impossible to narrow down the species. Just putting it out there in case anyone else sees one that is similar - [Melibe engeli](https://www.karollewall.com/melibe-engeli/) - Both times we have noticed this strange looking creature it was discovered swimming in the water column, laterally flexing back and forth and looking rather ragged and forlorn (ok, serious anthropomorphism there. . . ). They were likely dislodged from their home in Halimeda kanaloana beds near by, but just guessing there. Cory Pittman, on - [Geitadoris sp. # 3](https://www.karollewall.com/geitadoris-sp-3/) - These two geitodoris are a good example of how varied the colours can be in one species. At first I thought I had only found one large nudibranch, only to discover that the sponge I thought it was feeding on was another smaller animal. I was fortunate to find these in the lower intertidal zone - [Paradoris sp. #7](https://www.karollewall.com/paradoris-sp-7/) - Apparently this is one of two animals in this species recorded in Hawaii. This tiny, young paradoris (4-5 mm) was found at the edge of a large piece of broken-off grey sponge in less than 3 metres of water, Ma'alaea Bay, Maui. Whether it is rare or just rarely seen is always hard to know, - [Dendrodoris carbunculosa](https://www.karollewall.com/dendrodoris-carbunculosa-2/) - When a friend first spotted this nudibranch cruising across the open sand in South Maui, we were all a little baffled. It was clearly a dorid of some sort, but it was a good size (at least 6 inches or 15 cm) and the large, flowery tubercles were something we had never encountered. Fortunately, one - [Pacific Lion's Mane Jelly, Cyanea ferruginea](https://www.karollewall.com/pacific-lions-mane-jelly-cyanea-ferruginea/) - Return to Jellies of the Salish Sea The Lion's Mane Jelly (Cyanea capillata) is one of the largest animals in the sea. Its bell can reach a diameter of 3 metres and its tentacles can be as long as 35 metres. In recent years, scientists have determined that the Pacific Lion's Mane of the - [Fourspot Butterflyfish (Chaetodon quadrimaculatus)](https://www.karollewall.com/fourspot-butterflyfish-chaetodon-quadrimaculatus-2/) - Although Fourspot Butterflyfish are not abundant, they are still a relatively common sight on Maui. They usually pair up but are occasionally seen in small schools or alone. They are corallivores who feed primarily on Pocillopora (more commonly known as Cauliflower Coral) and will most certainly be one of the species negatively affected by large - [Fourspot Butterflyfish (Chaetodon quadrimaculatus)](https://www.karollewall.com/fourspot-butterflyfish-chaetodon-quadrimaculatus/) - Fourspot Butterflyfish are not abundant, but are still a relatively common sight on Maui. They usually pair up but are occasionally seen in small schools or alone. They are corallivores who feed primarily on Pocillopora (more commonly known as Cauliflower Coral) and will most certainly be one of the species negatively affected by large - [test page for featured image](https://www.karollewall.com/test-page-for-featured-image/) - https://www.karollewall.com/heaths-dorid-geitodoris-heathi/ https://www.karollewall.com/noble-sea-lemon-peltodoris-nobilis/ - [test for nudibranchs of hawaii](https://www.karollewall.com/test-for-nudibranchs-of-hawaii/) - [Thimble Jellies, Sarsia spp#](https://www.karollewall.com/thimble-jellies-sarsia-spp/) - There are likely two different species of Sarsias documented in these photos. I have tentively identified the jelly with the pinkish tentacles and bulbs as Sarsia princeps, but this could be challenged in the future. This is a note from Claudia Mills (cnidarian expert extraordinaire) regarding this particular jelly: "I don't feel comfortable putting names - [Bougainvillia spp.](https://www.karollewall.com/bougainvillia-spp/) - This may be my favourite jelly. Its very name, Bougainvillia, brings to mind tropical bougainvillea flowers bursting forth and that is indeed what the tentacles seem to be doing -- bursting from the four pinkish bulbs that mark the end of the four radial canals. It is a small medusa (less than 12 mm) and - [Cydippida Sp.](https://www.karollewall.com/cydippida-sp/) - Return to Ctenophores This is an undescribed species that has very obvious pinkish tentacles with very long sticky branches. It is more oval in shape than the Pacific Sea Gooseberry (Pleurobrachia bachei) and might at first be mistaken for the Eplokamis dunlopae. According to Cnidarian/ctenophore expert, Claudia Mills these ctenophores are usually found at - [White and Brown Nudibranch, Dendrodoris elongata](https://www.karollewall.com/white-and-brown-nudibranch-dendrodoris-elongata/) - Given it is relatively large compared to many of the dendrodoris in Hawaii (to 113 mm or almost 3"), this nudibranch seems to be quite elusive. The only animal I have ever seen was found by a friend in the tossing surf and sand of Ma'alaea Bay. It's not in great condition and we transferred - [Thordisa setosa](https://www.karollewall.com/thordisa-setosa/) - This Thordisa is easily mistaken for a Thordisa albomacula -- at least that was the case for me. Both nudibranchs have tenticular papillae that are slightly varied in height, but the setosa's tenticular processes tend to be a bit longer and it lacks the tell-tale white patch/band that extends directly forward of the albomacula's branchia, - [Hawaiian Knobby Flatworm, Thysanozoon tentaculatum](https://www.karollewall.com/hawaiian-knobby-flatworm-thysanozoon-tentaculum/) - An inconspicuous, very common flatworm that reveals itself to be quite stunning on close examination. In the field, their brilliant pink and white margin and gold-spotted papillae aren’t quite as noticeable as when seen through the microscopic lens of a camera. John Hoover's Flatworm page provides some more photos and detailed taxonomic history. The - [White Margin Nudibranch (Glossodoris rufomarginata)](https://www.karollewall.com/white-margin-nudibranch-glossodoris-rufomarginata/) - Nudibranchs of Hawaii Main Page This is an fairly common nudibranch for shallow free divers and snorkelers to see -- IF they are snorkelling in areas of sponge covered rubble -- especially grey sponge, their prey. They can, in fact, be quite abundant at certain times and in certain areas. All of these animals were - [Gloomy Nudibranch, Tambja morosa](https://www.karollewall.com/gloomy-nudibranch-tambja-morosa/) - Nudibranchs of Hawaii, Main Page Why this nudibranch has the common name of "gloomy" is beyond me. Its colour, shape and form are anything but. The black/green background is highlighted with deep china-blue spots, and gills that are a luscious blue-green, deep blue and black. There can be some variation on this and I have - [Kangaroo Nudibranch (Ceratosoma tenue)](https://www.karollewall.com/kangaroo-nudibranch-ceratosoma-tenue/) - Nudibranchs of Hawaii Main Page For the novice nudibranch detective, the Kangaroo Nudibranch is fairly easy to find during the day due to its striking colours, relatively large size (to 4" or 100 mm) and stiff, elongate body. We have only found them in the North Kihei, Ma'alaea area but there they are quite common - [Limenandra confusa](https://www.karollewall.com/limenandra-confusa/) - This tiny nudibranch is no bigger than 14 mm or 5/16", but when examined closely it is a lovely aeolid with brightly coloured rings on its mantle and unusually sized and spaced papillae on its cerata. These photos were taken in a protected rubbly, rocky area of North Kihei in less than one metre of - [Limenandra rosanae](https://www.karollewall.com/limenandra-rosanae/) - At first sight this is a fairly bland looking nudbranch as its cerata are a vague brown colour with spots (small papillae) and marks that match the seaweed or anemone food prey it is often found upon. Look closely and it has beautiful yellow and white rings with a centre that is tinged a slight - [Paradoris sp. #4](https://www.karollewall.com/paradoris-sp-4/) - Paradoris sp. #4 is yet another rarely seen animal, perhaps due to its diminutive size and rather bland colour. This particular 15 mm animal was discovered because I was pulling up some fishing line which had caught on some dead coral in the surge at Ma'alaea Bay, Maui. As I dove down to free the - [Coral Spotted Euryleptid or Pericelis](https://www.karollewall.com/coral-spotted-euryleptid-or-pericelis/) - This appears to be a newly documented, unidentified flatworm, hence the ambiguous title -- the Eryleptid or Pericelis part being a suggestion of Cory Pittman's. This beautiful little animal was found crawling through the middle of some grey sponge on a rocky, sponge-covered reef in less than 2 metres of water. Ma'alaea Bay, Maui. I - [Biuve cf. fulvipunctata](https://www.karollewall.com/biuve-cf-fulvipunctata/) - I came across this rather tiny (10 mm) well-camouflaged headshield sea slug in an area of North Kihei that was severely damaged by the Kona low storm of December 5/6th, 2021. Where once there was a vibrant community of algae and sponge, tunicates, opistobranchs and numerous other invertebrates, all that remained two months later was - [Polycera sp. #3](https://www.karollewall.com/polycera-sp-3/) - This teensy little nudibranch was not only hard to spot at a whopping 3-4 mm, it looks nothing like what you might be searching for in the opistobranch world. It really just looks like a broken off piece of sponge or left over algae. Until it moves or manages to draw attention to its bizarre, - [White-tip nudibranch, Baeolidia salaamica](https://www.karollewall.com/white-tip-nudibranch-baeolidia-salaamica/) - The original joy of discovering this aeolid happened more in the virtual darkroom than upon discovery. I was actually hit on the head by the rock that housed the two nudibranchs documented here. I'm not sure what their experience was prior to contact, but I'm sure it wasn't pleasant. The rock was no bigger than - [Brown-lined Paper Bubble Shell, Hydatina physis](https://www.karollewall.com/brown-lined-paper-bubble-shell-hydatina-physis/) - This little bubble shell is absolutely gorgeous, especially when caught in the light of day. They are generally nocturnal, but this one was out in the open in the heat of mid-day wandering across the sand and rubble of a tidepool formed by an accretion platform in Ma'alaea Bay, Maui. Bill Rudman's site, the Sea - [Elysia obtusa](https://www.karollewall.com/elysia-obtusa/) - I have only ever seen one of these Elysia obtusa-- a juvenile that was no bigger than 4 mm. Its bright emerald green colour threw me off an initial identification as these are usually more of a goldish-yellow colour. There is some suggestion that the strong green colour corresponds with a recent feeding and - [Tenellia sp. #5](https://www.karollewall.com/tenellia-sp-5/) - This is an extremely tiny aeolid -- no more than 4-5 mm. I spotted the egg mass long before I noticed these stunning orange and white Tenellia. There were two animals caught in a collection of marine debris -- fishing line, twigs, tiny bits of plastic and beads along with the hydroids this nudibranch species - [Tenellia sp. #25](https://www.karollewall.com/tenellia-sp-25/) - This is a tiny aeolid nudibranch that reaches a maximum of 20 mm or 3/4". They are likely not an animal that a snorkeler will be lucky enough to see -- though their prey, the Pennaria disticha hydroid (Christmas Tree hydroid) is found in fairly shallow waters. These three tenellia were found in North Kihei, - [Orange-spotted Flatworm, Pseudoceros 17](https://www.karollewall.com/orange-spotted-flatworm-pseudoceros-17/) - Though I have yet to see one of these flatworms, it is a rather common sight for my fellow snorkelers. The have found it out on the reef and in the sand (in broad daylight) in the North Kihei and Ma'alaea Bay area of Maui. Approximately 1" or 25 mm in 6-15 ft (2-5 m) - [Small Sea Hare, Aplysia elongata](https://www.karollewall.com/small-sea-hare-aplysia-elongata/) - These animals (all varied in colour -- from cream to green to brown/black to pinkish red) were found in a semi-protected rock, rubble, algae and sponge covered area of North Maui or in Ma'alaea Bay. Though they apparently grow to 40 mm (1.5"), these were all less than an inch and the juvenile was no - [Gymnodoris sp. #6](https://www.karollewall.com/gymnodoris-sp-6/) - This is a very small gymnodoris, generally reaching no more than 1/2" or 12 mm. At first I thought this was a juvenile Gymnodoris okinawae due to it obvious white markings, but the club-like rhinophores were clearly different in shape. Though they are apparently common, I have found only two of them and both were - [Euryleptid D](https://www.karollewall.com/euryleptid-sp/) - This appears to be another newly documented species to Hawaii and perhaps elsewhere. After consultation with Cory Pittman and John Hoover, I am going with their conclusion that it is an unidentified Euryleptid species based on its similarity to this flatworm from Singapore. I wrongly assumed it was a Thysanozoon or Acanthozoon as the - [Stick-bug Aeolid, Phyllodesmium sp. #1](https://www.karollewall.com/stick-bug-aeolid-phyllodesmium-sp-1/) - It's probably unfair to give this beautiful aeolid the common name of "stick-bug" but that's what struck me when I first saw it and Phyllodesmium sp. #1 is not an easy name to remember!. Though relatively small it is long and narrow with very long cerata. Both these animals were found during the day, which - [Kaloplocamus ramosus](https://www.karollewall.com/kaloplocamus-ramosus/) - This small nudibranch is a rare find -- especially moving at a good clip across the sand in broad daylight. It is more commonly found at night wandering about Halimeda beds or exposed rocky sites. This little one was between 15 and 18 mm or 3/4" at best. Found in less than 8 ft or - [Giant or Eared Sea Hare, Dolabella auricularia](https://www.karollewall.com/giant-or-eared-sea-hare-dolabella-auricularia/) - This is one of the largest Sea Hares in Hawaii (the Aplysia Argus is a similar size). On the reef it is easily mistake for a large, dead sponge. - [White-speckled Sea Hare, Aplysia argus](https://www.karollewall.com/white-speckled-sea-hare-aplysia-argus/) - White-speckled Sea Hares (sometimes called White-spotted or White-ringed) can get quite large, and the six inch (150 mm) reddish-tinged one in these photos looked clearly out of place in the very shallow tide pool where s/he was found. The very large light brown one, found by S. Caley in less than 2 metres of water, - [Ringed Sapsucking Slug, Plakobranchus ocellatus](https://www.karollewall.com/ringed-sapsucking-slug-plakobranchus-ocellatus/) - The Ringed Sapsucking Slug is one of the first sapsucking slugs I came across on Maui -- and by the dozens. They will often congregate and mate in huge masses, covering themselves in sand or wriggling around and on top of each other. Their beautiful blue and gold rings and violet-tipped rhinophores generally go unnoticed, - [cf. Prosthiostomid 3](https://www.karollewall.com/prosthiostomid-3/) - Though this flatworm is rarely found, I have come across a few over the past three years. All seem to be at different stages of development; however, very little is known about cf. Prosthistomid 3. The individual with the more defined line was just under an inch (20 mm) and was found in about 10 - [Glorious Flatworm, Pseudobiceros cf. gloriosus](https://www.karollewall.com/glorious-flatworm-pseudobiceros-cf-gloriosus/) - This is a beautiful little flatworm with a dark velvety centre, marked with a wide orange and narrow black margin. This particular one was found on top of a pinkish ascidian (feeding?) perched above a hole in the rock that it quickly disappeared into. Approximately 1", this glorious flatworm was found in a shallow lagoon - [Three-lined Flatworm, cf. Euryleptid 6](https://www.karollewall.com/three-lined-flatworm-cf-euryleptid-6/) - This little flatworm, cf. Euryleptid 6, is not commonly seen in Hawai, though it seems to be a little more diurnal than others -- often found on ledges and rubble in the intertidal zone. This particular worm was moving quickly across the edge of a shallow lagoon (less than 2 meters of water) and getting - [Mourgona? Sp. #2](https://www.karollewall.com/mourgona-sp-2/) - I'm afraid these photos are far from detailed or clear, but that has much to do with the fact that I had no idea what I was photographing. While being thrown about in the surge zone, I thought I had come across another Berthella pellucida, a fairly common side-gilled sea slug. Upon processing the image - [Berthellina Sp. #1](https://www.karollewall.com/berthellina-sp-2/) - When I first found these tiny side-gilled sea slugs, I assumed they were both juvenile representatives of the rather common Orange Gumdrop or Berthella delicata (sometimes referred to as Berthella citrina). I took several photos in an attempt to capture the visible eyes and shell only to find out when I processed the images that - [Pseudoceros C ??](https://www.karollewall.com/pseudoceros-c/) - This is a questionable identification, as are so many, but the closest I can come to a similar flatworm is one photographed and described by Cory Pittman on John Hoover's Flatworm site. At first I thought this was a variation on a Stella's Flatworm (Pseudobiceros-stellae) due to its dark background and white spots, but this - [Stella's Flatworm, Pseudobiceros stellae](https://www.karollewall.com/stellas-flatworm-pseudobiceros-stellae/) - At first this little flatworm appears to be nothing but a black, flat blob. Initially, I mistook it for the Black Dendrodoris -- a nudibranch of similar colour that also resides in pockets and little niches in rocks during the day. But upon closer examination it is actually quite "stellar" -- its dark blue/black body - [Facelinella or Phidiana semidecora](https://www.karollewall.com/facelinella-semidecora/) - This is a teensy nudibranch, reaching no more than 16 mm and it usually fits in with its surroundings quite well, making it almost impossible to see. The one that I photographed out on a white rock mid-day is showing unusual behaviour, perhaps because the intertidal zone where it was was full of rolling boulders - [Unknown A Flatworm](https://www.karollewall.com/unknown-a-flatworm/) - This semi-transparent flatworm is quite beautiful in its fine lace-like detail -- but I'm not sure what it is. It appears to be a mystery and is fairly rare. My identification relies on Cory Pittman's documentation of a similar worm on John Hoover's Flatworm site. This polyclad was found in under 2 metres of water - [Pilsbry's Headshield Slug, Tubulophilinopsis pilsbryi](https://www.karollewall.com/pilsbrys-bubbleshell-philinopsis-pilsbryi/) - Though these tiny slugs are usually nocturnal and rarely seen, this tiny bubbleshell (25 mm or 1") was found floating mid-water in broad daylight. It could have been injured as it took a lot to get it to settle into a niche in a sandy rock and to get a decent photo of it. Their - [Pseudocerotid J](https://www.karollewall.com/pseudocerotid-j-2/) - This beautiful flatworm remained completely oblivious to my presence for several minutes. It was approximately 15 - 18 mm and was found in less than 2 metres of water in a rubbly area of rock and algae in the Makena area of Maui. It was new to me, but Cory Pittman has documented it in - [Cestoplana rubrocincta](https://www.karollewall.com/cestoplana-rubrocincta/) - This long narrow flatworm with an orange mid-stripe and orange margin was found weaving its way through the rubble in North Kihei, Maui. It is the first of its kind that we know of to be documented east of Australia. It's difficult to say how long it was as it was in a ball when - [Wavy Bubble Shell, Micromelo scriptus](https://www.karollewall.com/wavy-bubbleshell-micromelo-undatus/) - I love these Bubble Shells -- my favourite colours all thrown into one beautiful, tiny slug. Like other members of the Aplustridae species, this slug lacks the ability to withdraw into its shell and is unable to protect itself by shutting the door (its operculum is non-existent). The animals documented here were all found in - [Winged Sea Slug, Gastropteron pacificum](https://www.karollewall.com/winged-sea-slug-gastropteron-pacificum/) - This sea slug is an absolute delight to watch as it makes its way up and down the water column, in and out of seaweed beds, flapping its wings effortlessly one minute and with what appears to be pure exhaustion the next. For the snorkeler or shallow free-diver it is not uncommon to see them - [Dinner Plate Jelly, Solmissus sp.](https://www.karollewall.com/dinner-plate-jelly-solmissus-sp-2/) - [Pacific Sea Gooseberry, Pleurobrachia bachei](https://www.karollewall.com/pacific-sea-gooseberry-pleurobrachia-bachei/) - There are only a few "gooseberry" jellies in the Pacific Northwest and this is perhaps the most common. It's more globe-like, circular form initially differentiates it from the two other less common oval-shaped ctenophores, the Euplokamis dunlapae and the undescribed Cydippida (For more information on plylum Ctenophore, UC Berkeley's Museum of Paleontology offers a quick - [Marine Life . . . etcetera](https://www.karollewall.com/marine-life-etcetera/) - [Redeye Medusa, Polyorchis penicillatus](https://www.karollewall.com/redeye-medusa-polyorchis-penicillatus/) - The Red-eye Medusa used to be a relatively common jelly. But over the past decade I have come across very few in the coves I frequent the most -- perhaps this is due to the demise of their habitat. They tend to feed in the lower benthic area bouncing off the eelgrass and algae, thereby - [Hanging Stomach Jelly, Stomotaca atra](https://www.karollewall.com/hanging-stomach-jelly-stomotaca-atra/) - This jelly gets its common name for obvious reasons. It wasn't until I saw it in action, using its stomach as a kind of sucking vortex on a Clytia Gregaria (see photo in gallery) that I realized that its design made some sense. - [Gregarious Jelly, Clytia gregaria](https://www.karollewall.com/clytia-gregaria/) - Look closely and you may see these tiny jellies boiling at the surface, or photo-bombing well planned underwater shots. They are indeed gregarious -- in a prolific kind of way (especially in Spring and Summer). It is not uncommon to see them caught in the stomachs or tentacles of other jellies and this is well-illustrated - [Cnidaria: Jellies and Ctenophora + the Odd Anemone](https://www.karollewall.com/jellies/) - This page is not meant to be used for identification of species; it's just a lovely gallery of pretty and unusual photographs of jellies and anemones. Links to ID sites of Cnidarians: Jellies and Siphonophores, and Ctenophores (i.e., Comb Jellies) are available through the sub-menu. - [Proboscidactyla flavicirrata](https://www.karollewall.com/proboscidactyla-flavicirrata/) - A rarely found jelly that I know very little about. However, there is a wonderful observation with an excellent discussion available on inaturalist. When I first submitted this image, Claudia Mills mentioned that these tiny jellies were often accompanied by hitch-hiking pandalid shrimp. This inat entry illustrates this well. - [Mitrocomella polydiademata](https://www.karollewall.com/mitrocomella-polydiademata/) - I've mistaken this jelly for a Mitrocomia cellularia (Cross Jelly) more than a few times. But these jellies often have a pinkish tinge to them (particularly around the edge of their bell margin) and they tend to be much more fleshy and are generally smaller. For more information and photos please see inaturalist. Claudia Mills - [Aglantha digitale](https://www.karollewall.com/aglantha-digitale/) - Aglantha digitale is a small but tall thimble-shaped jelly that is not commonly found in the Salish Sea, but is very common in polar regions.. It has numerous tentacles and rather obvious long, thin gonads that hang down from the cavity (in mature individuals). The photos I've included are rather poor --taken while hanging awkwardly - [Greater Moon Jelly, Aurelia labiata](https://www.karollewall.com/greater-moon-jelly-aurelia-labiata/) - A large Aurelia labiata, marked with horeshoe-shaped purple/pink gonads and an equally colourful fringe is a sight rarely forgotten. Seeing an entire bay absolutely full of them, so thick as to suggest one could easily skip across the water on the top of their bells. . .well, that is disturbing. I imagine there are other - [Four Tentacle Jelly, Solmundaegina nematophora (formally Aegina citrea)](https://www.karollewall.com/four-tentacle-jelly-aeginia-citrea/) - Return to Cnidarians: Jellies of the Salish Sea Four Tentacle Jelly is another common name for a jelly that includes several species. Their common feature is their long tentacle roots that run upwards to the top of the bell. The animals documented here all fall under the newly described Solmundaegina nematophora, but - [Catablema multicirratum](https://www.karollewall.com/catablema-multicirratum/) - At first, this jelly looks like a much larger version of a Catablema vessicarium sp. nodulosum but its tentacles are far more numerous and its stomach and gonads are generally lighter. I've included an image of my hand in behind an individual in order to provide a sense of scale. - [Black Spot Nudibranch, Joruna funebris](https://www.karollewall.com/black-spot-nudibranch-joruna-funebris/) - The Black Spot Nudibranch (Joruna funebris) is a fairly common species throughout the Indo Pacific, but is a relatively new species to Hawaiian waters. It is certainly not one that we see very often. The individual here was found in sand, in only a few feet of water as the photographers were exiting a beach - [Curtain Jelly, Eperetmus typus](https://www.karollewall.com/curtain-jelly-eperetmus-typus/) - See description below Return to Jellies of the Salish Sea Eperetmus typus is definitely not a common sight and is a pleasure to see despite its diminutive size. It is not difficult to mistake it for the Clinging or Orange Cross Jelly at first glance, but as Claudia Mills points out, "it lacks the adhesive - [Clinging Jelly (Orange Cross), Gonionemus vertens](https://www.karollewall.com/clinging-jelly-orange-cross-gonionemus-vertens/) - Description is below Return to Jellies of the Salish Sea It is always a treat to spot these small jellies in the intertidal and upper subtidal zone as they tend to hide in amongst the eelgrass, kelp and algae. Their orange gonads form a distinct cross and their multiple tentacles literally "cling" via a - [Fuzzy Onchidoris, Onchidoris muricata](https://www.karollewall.com/fuzzy-onchidoris-onchidoris-muricata/) - Another tiny (15 mm or 5/8" max?) white dorid nudibranch! This is a recent find (March 2021) and I mistook it, at first, for a Janna's Dorid, but the more rounded shape of the tubercles, lack of noticeable brown spot in the middle, bright white marking below gills, and different marginal features made me question - [Imogine sp. A](https://www.karollewall.com/imogine-sp-a/) - This beautiful, rather large worm (2" or 50mm) was spotted off of North Kihei, Maui in approximately 10 ft (3 metres) of water. It was just cruising across the sand in broad daylight. It varies a great deal in colour, so if you find a worm of this general size, with an orangeish margin, and - [Paraplanocera 1](https://www.karollewall.com/paraplanocera-1/) - This beautiful 1.5" (40 mm) flatworm was found swimming above the sand in the Waikuli area of West Maui. These are particularly beautiful images of a translucent species with a lace-like pattern -- a pattern often not fully appreciated when it is traversing the rocky reef or sand.

It also doesn't have the pendant stomach and frilly mouth, which should - [Jellies of the Salish Sea](https://www.karollewall.com/jellies-of-the-salish-sea-3/) - [Berthella pellucida](https://www.karollewall.com/berthella-pellucida/) - This tiny (15 mm) side-gilled sea slug was found in a shallow rocky reef in North Kihei in approximately 2 metres of water (6.5 ft). Look closely and you will see the shell underneath the transparent, cream mantle. More information can be found on the Sea Slugs of Hawaii website. - [Jellies of the Salish Sea](https://www.karollewall.com/jellies-of-the-salish-sea/) - [Thysanozoon or Acanthozoon B](https://www.karollewall.com/thysanozoon-or-acanthozoon-b/) - This tiny white, lightly speckled nudibranch was photographed in the Sugar Beach area of Maui in a few feet of water on a nearshore shelf that forms a tide pool at lowest tides. Not sure, but it could be a juvenile as it was no bigger than 12 mm. At first glance it appears to - [Pseudoceros Leptostictus](https://www.karollewall.com/pseudoceros-leptostictus/) - Back to Flatworms of Maui This beautiful flatworm was found in an area of rubble and worn reef in relatively shallow water off of North Kihei, Maui. For more images that illustrate the variation in colour and size, as well as detailed taxonomy, see John Hoover's flatworm page. - [Unknown Pseudocerotid](https://www.karollewall.com/pseudocerotid-j/) - This flatworm was found in North Kihei, Maui in less than 3 metres (10 ft) of water. Its identity remains unknown, so all we can offer is more information about a similar worm noted on John Hoover's flatworm page. - [Bay Pipefish, Syngnathus leptorhynchus](https://www.karollewall.com/bay-pipefish-syngnathus-leptorhynchus/) - [Pro ImageBrowser](https://www.karollewall.com/pro-imagebrowser/) - [Frontend Image Search](https://www.karollewall.com/frontend-image-search/) - [Pro Sidescroll](https://www.karollewall.com/pro-sidescroll/) - [Pro Tile](https://www.karollewall.com/pro-tile/) - [Basic ImageBrowser](https://www.karollewall.com/basic-imagebrowser/) - [Basic Thumbnail](https://www.karollewall.com/basic-thumbnail/) - [Postulose Phyllidia, Phyllidiella pustulosa](https://www.karollewall.com/postulose-phyllidia-phyllidiella-pustulosa/) - This nudibranch is rarely seen by snorkelers and shallow free divers on Maui.

For more information about this animal , please see Sea Slugs of Hawaii. - [Tom Smith Nudibranch, Ardeadoris tomsmithi](https://www.karollewall.com/tom-smith-nudibranch-ardeadoris-tomsmithi/) - This beautiful little nudibranch (to 28 mm or just over an inch) is fairly common in rocky, rubble areas and is always a pleasure to find. Though it is similar to the White Bump, Imperial Nudibranch and the Trembling Nudibranch, its undulating, wavy yellow and white margin, creamy white bumps, deep blue-tipped rhinophores and deep - [Shopping Cart](https://www.karollewall.com/shopping-cart-3/) - [Cardinal Nudibranch, Phyllidiopsis cardinalis](https://www.karollewall.com/cardinal-nudibranch-phyllidiopsis-cardinalis/) - This is one of those fairly common, rarely seen nudibranchs. It can vary significantly in colour, but maintains its warty appearance, notable yellow rhinophores and bright yellow foot. The 5 cm or 2" individual photographed here was found in approximately 2 metres (6ft) of water in North Kihe, Maui. They are primarily nocturnal, so this - [Black-margined Nudibranch, Doriprismatica atromarginata](https://www.karollewall.com/black-margined-nudibranch-doriprismatica-atromarginata/) - The lighter version of the Black-margined Nudibranch documented here was actually photographed in Raja Ampat. The Hawaiian animal is significantly darker than those generally seen in Australia/Indonesia. Both the images of the small group feeding on brown sponge and the lone Black-margined were found in less than 10 ft or 3 metres of water - [Lees in Covid Times . . .](https://www.karollewall.com/lees-in-covid-times/) - [Hermit Crabs of Maui, Hawaii,](https://www.karollewall.com/hermit-crabs-of-maui-hawaii/) - Hermit crabs only have a hard exoskeleton on the appendages and must conceal their soft body parts within empty gastropod shells. They will exchange shells as they grow and may need to fight other crabs to do so. They are especially active at night and may be seen by the hundreds in shallow tide pools. - [Guam Hermit Crab, Calcinus guamensis](https://www.karollewall.com/guam-hermit-crab-calcinus-guamensis/) - [White Hermit Crab, Calcinus cf. revi ?](https://www.karollewall.com/white-hermit-crab-calcinus-cf-revi/) - Not absolutely sure on this identification, hence the ???. - [Jeweled Anemone Hermit Crab, Dardanus gemmatus](https://www.karollewall.com/jeweled-anemone-hermit-crab-dardanus-gemmatus/) - [Unidentified Acotylean 2](https://www.karollewall.com/unidentified-acotylean-2/) - This is another Unidentified Acotylean. It's colour is a brownish-pink; it almost looks "hairy" and its few eye spots are so concentrated on its short dorsal tentacles that it actually appears to have two solid eyes. The only animal we have found that comes close to this is one that Cory Pittman suggests "may be - [Thysanozoon cf. brocchii? (Juvenile)](https://www.karollewall.com/thysanozoon-cf-brocchii/) - At first I thought this teensy juvenile flatworm was just another sighting of the fairly common Hawaiian Knobby Flatworm (Thysanozoon tentaculatum) with longer papillae. This identification has since been questioned and Cory Pittman has suggested that it is most likely a juvenile Thysanozoon cf. brocchii -- "that species has spindle-shaped papillae and some aspects of - [White-stripe Flatworm, Pseudobiceros 11](https://www.karollewall.com/white-stripe-flatworm-pseudobiceros-11/) - This is quite an attractive flatworm, with its white rolling margin and central white stripe on a gold-flecked background. It's small (about 1' or 25 mm) and can easily be mistaken for a really tiny White-margin nudibranch -- until it moves, undulating acoss the rocks at a speed no glossodoris could possibly replicate. Found in - [Unidentified Acotylean.](https://www.karollewall.com/unknown-flatworm-a/) - I haven't got a clue what this flatworm is. At first I thought it was similar to the worm "Unknown A" on John Hoover's site, but Cory Pittman suggested that it differs significantly from the species he photographed as this worm has dorsal tentacles while his does not. So, once again, nothing is for - [Kathy's Thuridilla, Thuridilla kathae](https://www.karollewall.com/kathys-thuridilla-thuridilla-kathae/) - Thuridilla kathae is a tiny little sapsucker that resembles a few other Elysias and Thuridillas, so make sure you haven't found a Thuridilla carlsoni, an Elysia degeneri, or Elysia lobata . This little one (1/2 inch or 12 mm maximum) was found in 1 metre or 3 ft of water in amongst the rocks and - [Green Sea Turtles](https://www.karollewall.com/green-sea-turtles/) - [Carminodoris bifurcata](https://www.karollewall.com/carminodoris-bifurcata/) - More info to come. In the meantime, please check out Sea Slugs of Hawaii. - [Gold Lace, Halgerda terramtuentis](https://www.karollewall.com/gold-lace-halgerda-terramtuentis/) - Well, this is a fun one -- definitely striking and deserving of its wonderful names. Gold lace obviously relates to its delicate, transparent body etched in gold. Earthwatch? That name ties into the taxonomic name, Halgerda terramtuentis, which means "looking at the earth with care" in honour of the Earthwatch Institute's volunteers who helped chief - [Pseudobiceros kryptos?](https://www.karollewall.com/pseudobiceros-kryptos/) - Found in less than 1 metre (3.3 ft) of water in a surge zone in the lagoons at Makena Landing, S. Maui. Approximately 40 mm? Since this animal has multiple variations in colour and identification was initially difficult, please see John Hoover's Hawaii Flatworms site for other photos and information. - [Bulbaeolidia paulae](https://www.karollewall.com/bulbaeolidia-paulae-2/) - The novice can easily mistake this nudibranch for the Bulbaeolidia alba. Both have pronounced bulbous swellings on their rhinophores. Unlike the alba, the paulae does not rhythmically "click" along, it is more than twice the size at maturity and it has much more defined white tips on its more abundant cerata. It is also rarely - [Leptoplanid sp. ?](https://www.karollewall.com/leptoplanid-sp-1/) - At present I can find no known visual examples of a flatworm that fits this individual's description, but the position of its eye spots and its ability to stretch out significantly suggest a Leptoplanid of some sort. Found under a rock in 1.5 metres of water (4.5 ft), Makena Landing, South Maui. At least 40 - [Night Flatworm, Tytthosoceros nocturnus](https://www.karollewall.com/night-flatworm-tytthosoceros-nocturnus/) - This is a relatively rare flatworm. At first, I thought it was a Stella's Flatworm (very common) and unfortunately didn't take too many photos of it. It clearly lacks the white spots that dot the Stella's, but this particular individual had a couple of white spots on its body. Its tell-tale features, however, are the - [Doris pecten](https://www.karollewall.com/doris-pecten/) - [Okinawa Gymnodoris, Gymnodoris  okinawae](https://www.karollewall.com/okinawa-gymnodoris-gymnodoris-okinawae/) - The intricate patterns on the body of this Gymnodoris are unbelievably complex and beautiful, especially in mature individuals. Younger animals are a translucent creamy/white with orange dots and white spots or markings that are quite pronounced. As they get older the orangey-red lines seem to merge and squiggle, creating a map-like image when combined with - [Tenellia Sp. #1](https://www.karollewall.com/tenellia-sp-1/) - Extremely tiny (7 mm or less than 1/3"), beautiful little aeolid, found in about 5 ft of water off of Sugar Beach, Maui. Until this is updated, please check out the Sea Slugs of Hawaii site for more information. - [Thysanozoon or Acanthozoon A](https://www.karollewall.com/thysanozoon-or-acanthozoon-a/) - Once again I am not sure about the identification of this flatworm. I have turned to the experts and John Hoover's Hawaii Flatworm site will probably just confirm my confusion. Do I have two different species of worms here or a pinkish-red version and a brownish version of the same species? - [Paraplanocera marginata?](https://www.karollewall.com/paraplanocera-marginata-or-paraplanocera-10/) - This is a very pretty flatworm and finding it wandering across rocks and sand in a tidepool was quite the treat. Even as it moved it remained fairly circular in shape and its banded nuchal tentacles and purple-edged, varigated stood out against its white-speckled, goldish/brown body. I hesitate to confirm whether this is a Paraplanocera - [Benthic Ctenophore?](https://www.karollewall.com/benthic-ctenophore/) - At first I thought this was some kind of tunicate, but then it moved slightly. A flatworm? Nope. Apparently it is a Benthic Ctenophore? I'm not sure which kind, but here's some more information on this particular type of Comb Jelly: Benthic (bottom-living) ctenophores A few ctenophores (those in the order Platyctenida) live on the - [Kato's Flatworm, Phrikoceros cf. katoi](https://www.karollewall.com/katos-flatworm-phrikoceros-cf-katoi/) - Initially we assumed this flatworm was a Spanish Dancer, Hexabranchus pulchellus. Who is mimicking whom is a good question, but the similarities are fairly obvious. - [Purse Shell Flatworm, Pericelis 4 or Pericelis hymanae?](https://www.karollewall.com/purse-shell-flatworm-pericelis-4/) - This is a relatively common flatworm, found beneath rocks and generally hiding in or under purse shell oysters (Isognomon perna) during the day. There is some discussion as to whether these flatworms are Pericelis #4 or Pericelis hymanae. - [Julia exquisita](https://www.karollewall.com/julia-exquisita/) - Finding this teensy teensy sapsucker was indeed unexpected. I brushed against a batch of caulerpa sea weed in a shallow, rock filled intertidal zone and noticed that one of the segments was actually moving. These little "exquisite" sacoglossa are no bigger than 7 mm and this one was a little less than that (i.e., no - [Paraplanocera oligoglena](https://www.karollewall.com/paraplanocera-oligoglena-2/) - This is apparently a relatively common flatworm, perhaps because it is easily found by tide-poolers and shallow snorkelers. It is fairly round and can reach up to 70 mm or 3". Both individuals were found at Makena Landing in approximately 6 ft or 2 metres of water in an area of surge and tossed, algae - [Paraplanocera oligoglena](https://www.karollewall.com/paraplanocera-oligoglena/) - This relatively large flatworm (up to 70 mm or 3 ") is apparently fairly common. Perhaps this is because of its size and its general preference for shallow, intertidal areas which are more accessible to the tidepooler and snorkeler. It has rather obvious nuchal head tentacles that are striped and banded by eye spots at - [Pericelus ? A](https://www.karollewall.com/pericelus-a/) - This is a creamish/whitish flatworm with brown splotches that continue nearly to the edge of its body. There is no noticeable margin but it has very obvious marginal tentacles. As it traveled across the rocks at a fabulous speed it took on an oval, round and elongated shape. There is still some debate as to - [Pseudoceros E.

It may be a juvenile as its white speckles have yet to form a continuous central line, and they are much larger in proportion to its body than those photographed by Cory Pittman on John Hoover's - [False Goldrim Flatworm, Pseudobiceros #14](https://www.karollewall.com/false-goldrim-flatworm-pseudobiceros-14/) - This beautiful flatworm can easily be mistaken for the Goldrim Flatworm, but it is far more "ruffly", both marginally and around its pseudo-tentacles. This particular individual (and I have only seen one of these relatively rare flatworms) was found in a backwater lagoon in La Perouse Bay. At one point (when we gently moved its - [Goldrim Flatworm, Pseudoceros paralaticlavus](https://www.karollewall.com/goldrim-flatworm-pseudoceros-paralaticlavus/) - This flatworm can be found (very occasionally) during the day hiding under the edge of rocks or in crevices, though it is primarily nocturnal. All animals photographed here were found in North Kihei, Makena Landing or La Perouse Bay, Maui in less than 2 metres (6 ft) of water. For more images and information, check - [Lined Sea Hare (Stylocheilus striatus)](https://www.karollewall.com/lined-sea-hare-stylocheilus-striatus/) - My first encounter with the Lined Sea Hare involved getting hit over and over again by tiny sticky brown blobs as I walked through a shallow tide pool at low tide. They were everywhere, drifting in the current, catching themselves on rocks and floating algae, and getting washed out to sea as the tide rose. - [Blue Swallowtail Slug, Chelidonura hirundinina](https://www.karollewall.com/blue-swallowtail-slug-chelidonura-hirundinina/) - My first sighting of these tiny headshield slugs involved literally getting hit in the mask with them. I encountered a bloom in a back lagoon and these little black specks were everywhere -- crawling over rocks, clinging to each other, and spinning in the current and waves. Upon further examination, these black spots appeared to - [Decorated Nudibranch, Goniobranchus decorus](https://www.karollewall.com/decorated-nudibranch-goniobranchus-decorus-2/) - [Decorated Nudibranch, Goniobranchus decorus](https://www.karollewall.com/decorated-nudibranch-goniobranchus-decorus/) - Until this is updated, please see Sea Slugs of Hawaii for more information. These tiny animals were both found in less than 1 metre of water, wandering about sand, rubble and spongy reef areas off of North Kihei and Sugar Beach, Maui -- unusual behaviour for a nocturnal nudibranch. - [Mourgona (?) sp. #5](https://www.karollewall.com/mourgona-sp-5/) - The individual documented here was so tiny (3-5 mm) that it was barely visible to the naked eye. It fit into its background so well as to be almost invisible (and indeed was to fellow snorkelers). This little one was found on a ball of algae that was about fist-sized. Its cerata were completely intact - [Polybranchia samanthae](https://www.karollewall.com/polybranchia-samanthae/) - This little sapsucker is a little dificult to spot. It's nocturnal, and if it does happen to be "awake" during the day it blends in so very well with the algae it relies upon for food and camouflage. Look closely and you will see that it has lovely white edging on its translucent cerata -- - [Elysia lobata](https://www.karollewall.com/elysia-lobata-2/) - We have only ever found one of these (apparently common) diurnal animals. Perhaps it is because they are TINY (12 mm) and nearly invisible, as they blend in so well with the rocky, sand, sponge and algae covered areas they feed in. We only have one image, so please see Sea Slugs of Hawaii for - [Polybranchia jensenae](https://www.karollewall.com/polybranchia-jensenae/) - Finding one of these sapsuckers is indeed a treat. They are nocturnal, so discovery generally involves looking very closely at the algae in the shallows and determining whether it's an animal or a plant. The jensenae is often confused with the Polybranchia samanthae or Cyerce elegans. Though they can autotomize their cerata (as seen - [Test for Front Page album](https://www.karollewall.com/test-for-front-page-album/) - [Gymnodoris sp.#2](https://www.karollewall.com/gymnodoris-sp-2/) - I find it nearly impossible to tell the difference between the Gymnodoris bicolor and Gymnodoris sp.#2. According to Sea Slugs of Hawaii, the primary differences are that Gymnodoris sp.#2 has more pronounced nipples on the tips of their rhinophores (often tinted orange), and their genital pore is forward of a more closed horseshoe-shaped branchial plume - [White Gymnodoris, Gymnodoris alba](https://www.karollewall.com/white-gymnodoris-gymnodoris-alba/) - This tiny gymnodoris (less than an inch or 11 mm) has only been found once by our group of snorkelers and free divers -- in an area where Gymnodoris okinawae seem to dominate. It was found in a few feet of water (less than a metre), in a protected area in North Kihei filled mostly - [Noumeaella rehderi](https://www.karollewall.com/noumeaella-rehderi/) - This is an exquisitely beautiful, very tiny aeolid that is pretty much impossible to see unless it is on a stark, contrasting background. The long fringe-like papillae on their rhinophores are stunning, but basically only visible with a macro lense. The animals photographed here were found in both North and South Kihei/Makena area in less - [Noumeaella rehderi](https://www.karollewall.com/noumeaella-rehderi-2/) - [Sphinx Phyllidia, Phyllidiopsis sphingis,](https://www.karollewall.com/sphinx-phyllidiaphyllidiopsis-sphingis/) - This is not a common sight in the shallow waters around South Maui, where we usually snorkel, and so it is a pleasure to find. It is relatively flat and thin with no tubercles, but it can still be mistaken for a juvenile or paler version of the Phyllidia varicosa. This animal was found in - [Scrambled Egg Nudibranch, Phyllidia varicosa](https://www.karollewall.com/scrambled-egg-nudibranch-phyllidia-varicosa/) - This is a rather large and common diurnal nudibranch and it is often found under reef edges and caves or snuggled into holes in spongy/rocky areas. It can be a little difficult for the novice to distinguish between juvenile Phyllidia varicosa and some Sphinx Phyllidia as some varicosa can be entirely missing the identifying marker - [Lilac-spotted Nudibranch, Chromodoris aspersa](https://www.karollewall.com/lilac-spotted-nudibranch-chromodoris-aspersa/) - This is a fairly common nudibranch that seems to be rarely found due to its habit of hiding under rocks during the day. These two animals illustrate the colour-variance in the gills and rhinophores (some orange, some yellow). They were found in about 3 ft (1 metre) of water at low tide, in a relatively - [Egg Eating Nudibranch, Favorinus japonicus](https://www.karollewall.com/egg-eating-nudibranch-favorinus-japonicus-3/) - These animals were all found in less than 4 ft of water in Nth Kihei. Until this is updated, please see Sea Slugs of Hawaii. - [White Spotted Nudibranch, Goniobranchus albopunctatus](https://www.karollewall.com/white-spotted-nudibranch-goniobranchus-albopunctatus-3/) - More info coming soon.

Unlike more scientific sites, I have organized these in a way that may be more novice friendly. When I was first learning about sea slugs I would look for colours and shape - [Trembling Nudibranch, Goniobranchus vibratus](https://www.karollewall.com/trembling-nudibranch-goniobranchus-vibratus/) - The Trembling Nudibranch is another fairly common yellow, white, bluish/purple nudibranch -- sharing its basic colouring and genus with both the Imperial and the Tom Smith. But unlike the Imperial, which has yellow spots against a white mantle, the Trembling is covered in white spots against a yellow mantle. Both have a purple/blue marginal line - [Black Dendrodoris, Dendrodoris nigra](https://www.karollewall.com/dendrodoris-nigra/) - These Black Dendrodoris are fairly common, and once you manage to spot one, it's likely you will spot many. At first, I thought I was seeing small brown sea cucumbers or drab brown Common Sea Hares. But once I came across an older individual covered in spots it became easy to tell the difference. Even - [Red Dendrodoris, (Dendrodoris rubra or Dendrodoris Sp.#1)](https://www.karollewall.com/red-dendrodoris-dendrodoris-rubra/) - We found this relatively rare and largish nudibranch (approximately 7 cm or 3") in less than 1 metre (3 ft) of water in broad daylight on the algae covered reefs of Maui's West side. Although this particular animal is an obvious bright red with yellow margins, the species comes in darker and lighter varieties. They - [Gold Lace (or Earthwatch) Nudibranch, Halgerda terramtuentis](https://www.karollewall.com/gold-lace-or-earthwatch-nudibranch-halgerda-terramtuentis/) - Well, this is a fun one -- striking and, unfortunately, one I have never seen. But the colleagues who have contributed images here have found it floating in the water column, tucked into crevices and out on the sand. It makes one wonder if this species isn't easily dislodged as it is not a "swimmer." - [Uhu Parrotfishes (most commonly seen by snorkelers on Maui)](https://www.karollewall.com/parrotfishes-most-commonly-seen-on-maui/) - Female Ember (Redlip) Parrotfish Scarus rubroviolaceus Male Ember (Redlip) Parrotfish Click on the thumbnails to view galleries or scroll over titles.

This one is often confused with the Dot and Dash or Hyselodoris bertschi as it too can have broken blueish lines and has the tell-tale orange and white-lined rhinophores. See Bill Rudham's post in Sea Slug Forum if you're interested in - [White-spotted Pleurobranch, Pleurobranchus varians](https://www.karollewall.com/white-spotted-pleurobranch-pleurobranchus-varians/) - These side-gilled slugs are fairly difficult to see as they really look like a sponge or bryzoan, especially when lying flat or tucked into a hole or under a ledge. If you look closely, the pattern beneath the white spots is fairly similar to that found on the Polygon Pleurobranch, and given its colour it - [Dot & Dash Nudibranch, Hypselodoris bertschi](https://www.karollewall.com/dot-dash-nudibranch-hypselodoris-bertschi/) - The Dot & Dash nudibranch is apparently one of the most common diurnal nudibranchs found in Hawaiian waters (see Sea Slugs of Hawaii), but we have found others to be far more common in the Kihei/Ma'alaea area. Like the Locust (Pease's), the Danielle's and the Kahuna, this is a small, elongate nudibranch with a white/transluscent - [Violet-gilled Nudibranch, Hypselodoris violabranchia](https://www.karollewall.com/violet-gilled-nudibranch-hypselodoris-violabranchia/) - These beautiful nudibranchs are quite tiny, relatively long and thin. As a size comparison, I've provide an image of a 2 inch Imperial nudibranch making its way over top of a Violet-gilled's gills. They get to be 20 mm or 3/4 of an inch -- so look closely at those tiny tubular shells and bits - [Home 5](https://www.karollewall.com/home-5/) - [Home 4](https://www.karollewall.com/home-4/) - [Glorious Noumea, Verconia Sp.#4](https://www.karollewall.com/glorious-noumea-verconia-sp-4/) - This beautiful little nudibranch is fairly rare, but all individuals seen here were documented in water between 2 and 3 metres and found on relatively exposed rocky reefs or near a broken shoreline. Their unbroken white stripe mid-notum is generally what distinguishes them from the similar (but elusive to me) Verconia varians. Look closely, however, - [Home 3](https://www.karollewall.com/home-3/) - [Bi-colour Gymnodoris, Gymnodoris bi-color](https://www.karollewall.com/bi-colour-gymnodoris-gymnodoris-bi-color-2/) - These little Bi-colour Gymnodorises were all found in a few feet of water wandering about the algae and rocks of a traditional fishpond. At first they appear to be nothing but small orange or yellow elongate blobs (they come in cream and pink too!) but on close inspection they are quite beautiful, with horseshoe-shaped branchial - [Bi-colour Gymnodoris, Gymnodoris bi-color](https://www.karollewall.com/bi-colour-gymnodoris-gymnodoris-bi-color/) - These little Bi-colour Gymnodorises were all found in a few feet of water wandering about the algae and rocks of a traditional fishpond.

For the novice, it seems especially close to the Kahuna Nudibranch and several others: the Locust Nudibranch (Pease's), the Violet Gill, and the Dot and Dash, all have similar long, narrow bodies and colours. The Danielle's seems to be - [White-Margin Nudibranch (Glossodoris rufomarginata)](https://www.karollewall.com/white-margin-nudibranch-glossodoris-rufomarginata-2/) - There are times when the conditions are right and the territory is welcoming that it is possible to see several of these White-Margined Nudibranchs in one day. Despite their commonality, there is something sweet about this caramel-coloured critter that pleases every time. They are generally around 25mm or 1" but I can attest to seeing - [Fellow's Nudibranch, Peltodoris fellowsi](https://www.karollewall.com/fellows-nudibranch-peltodoris-fellowsi/) - This bright white, snow-coloured firmly-mantled nudibranch definitely stands out on the reef. The only individual I have ever seen was in about 10 ft of water, snuggled into a small cave ledge and difficult to photograph. . See Sea Slugs of Hawaii if you are wanting more images and confirmation as to whether it is - [Yellow Margin Nudibranch, Ardeadoris angustolutea](https://www.karollewall.com/yellow-margin-nudibranch-ardeadoris-angustolutea/) - Another relatively small nudibranch! These individuals were no more than 3/4" and some were no more than 10 mm. The darker individuals are easily mistaken for White-margin Nudibranchs when seen from a distance (see bottom two images taken by Bruce W.). But upon closer examination the "Angus", as we typically call them, have a yellowish-white - [Lilac Ceratomsoma, Ceratosoma sp. #2](https://www.karollewall.com/lilac-ceratomsoma-ceratosoma-sp-2/) - I wasn't even certain I had found another nudibranch when I came upon this individual. Ceratosoma sp. #2 are especially tiny, reaching 8 mm (1/3") when mature. It wasn't until I looked closely at the camera image that I realized this little nudibranch was quite beautiful, with a stand out tail, a yellow margin on - [Imperial Nudibranch (Hypselodoris imperialis)](https://www.karollewall.com/imperial-nudibranch-hypselodoris-imperialis/) - The Imperial nudibranch is perhaps the most common nudibranch found in shallow waters off of Maui. It is especially noticeable if it is found trailing another of its kind -- a fairly common sight and one which is not really understood. They have to be thanked for encouraging so many snorkelers to open their eyes - [White Bump Nudibranch, Goniobranchus albopustulosus](https://www.karollewall.com/white-bump-nudibranch-goniobranchus-albopustulosus/) - Another nudibranch of the chromodoris family with white, yellow, and purplish/blue/brown as its signatory colours. It does differ significantly from its look-a-likes however, due to its all-white gills and more brownish rhinophores. It also seems to be far less common -- likely due to its nocturnal nature and preference for dark shady spots. The Imperial, - [Elysia Sp.#2](https://www.karollewall.com/elysia-sp-2/) - This photo of a very tiny Elysia (less than 10 mm -- around 1/3 ") was taken in a shallow protected area of North Shore, Maui. It is apparently a fairly common diurnal species that sometimes jerks and clicks its parapodia -- and it is this movement that drew the attention of the photographer. It - [Sea Slugs of Hawaii: Nudibranchs](https://www.karollewall.com/sea-slugs-of-hawaii-nudibranchs/) - The sea slugs documented below are all members of the order nudibranchia -- those slugs with. . . - [Limenanda confusa](https://www.karollewall.com/limenanda-confusa/) - This tiny nudibranch (12 mm) of the aeolid family was spotted in a few feet of water inside a protected, traditional Hawai'ian fishpond on Maui. According to Cory Pittman and Pauline Fiene this is a relatively common diurnal species, but it's diminutive size and brilliant camouflage makes it rather difficult to see. - [Lilac Dorid, Discodoris lilacina](https://www.karollewall.com/lilac-dorid-discodoris-lilacina/) - Welcome to the confusing and colourful Lilac Dorid, also called the Discodoris lilacina, the Discodoris fragilis, Tayuva lilacina and Doris lilacina. There are three different individuals photographed here -- a very tiny (.3 in or 8 mm) bluish juvenile (close to a blue food sponge), a small, more lilac coloured one (1 in or 2.5 - [fed up](https://www.karollewall.com/fed-up/) - testing to see what happens when I add text - [test of galleries](https://www.karollewall.com/test/) - Testing galleries - [Jolly Green Giant, Miamira sinuata](https://www.karollewall.com/jolly-green-giant-miamira-sinuata/) - So, this is the holy grail of sea slugs. Or one of them. Search for "Holy Grail Nudibranchs" and you'll come up with more than a few. But on Maui I'd say these provide as much of a thrill upon discovery as a Pikachu. And that's pretty significant. They are beautiful. There are not many - [Dendrodoris carbunculosa](https://www.karollewall.com/dendrodoris-carbunculosa/) - When a friend first spotted this nudibranch cruising across the open sand in South Maui, we were all a little baffled. It was clearly a dorid of some sort, but it was a good size (at least 6 inches or 15 cm) and the large, flowery tubercles were something we had never encountered. It turned - [Blue-spot Nudibranch, Dendrodoris denisoni](https://www.karollewall.com/dendrodoris-denisoni/) - I have not been privileged enough to find this nudibranch myself, but it is definitely one that has incited future treasure hunting. Thanks to my fellow "nudi nerds" I have some images to share. These animals come in varying colours of light brown, beige, reddish-brown and white. Their relatively large fleshy turbercles are most notable; - [test 3 sept 12](https://www.karollewall.com/ahihi-kinau-butterflyfish/) - Butterflyfish Galleries of each species of Butterflyfish are coming soon! - [Test page](https://www.karollewall.com/test-page-2/) - [Opisthobranchs: Nudibranchs, Sea Slugs and Sea Hares of Hawaii](https://www.karollewall.com/nudibranchs-sea-slugs-and-sea-hares-of-hawaii/) - This page is set up for those who happen to land here from the outer interweb in hopes of identifying a nudibranch, bubble shell, sea hare, or some variety of sea slug or look-a-like.

Focus hard enough on what you want, dedicate yourself to saving the ocean and its creatures - [Giant Pink Star, Pisaster brevispinus](https://www.karollewall.com/giant-pink-star-pisaster-brevispinus/) - The Giant Pink Star can get as large as the Sunflower star and individuals have been found that were around a metre across (3.2 ft). Most of the mature ones I have seen have been around 2 ft or 60 cms. https://seastarsofthepacificnorthwest.info/giant-pink-star.html - [Snow goddess, Ardeodoris poliahu](https://www.karollewall.com/snow-goddess-ardeodoris-poliahu/) - This is another beautiful nudibranch that I thought had completely eluded me. But on closer inspection of a teensy teensy white bump on some algae, I discovered that I have indeed seen a juvenile of this species. Terrible photo, but it's here anyway. If you look really closely you'll see the "snowflakes" on its notum - [Blue Dragon, Pteraeolidia semperi](https://www.karollewall.com/blue-dragon-pteraeolidia-semperi/) - Apparently, this nudibranch is one of the most commonly sighted aeolids in Hawaii. That's not been my personal experience. I had to fly half way around the world to see one. So two of the images seen here are from Molokini, Maui and the rest are from a mucky, swirly, high current area near Manado, - [Red Spotted Nudibranch, Goniobranchus heatherae](https://www.karollewall.com/red-spotted-nudibranch-goniobranchus-heatherae/) - The Red Spotted Nudibranch - [Glorious Noumia, Verconia sp.#4](https://www.karollewall.com/glorious-noumia-verconia-sp-4/) - This beautiful tiny nudibranch is fairly rare and easily confused with the Verconia varians (also relatively rare). One of the young individuals documented here actually looks more like the varians as it has a broken line, but is consistent with the sp.#4 in that the tips of its rhinophores are orange and its body - [Bubble Shells, Aplustridae](https://www.karollewall.com/bubble-shells-2/) - Click on the thumbnails below for further images and information on each species. - [Bulbaeolidia paulae](https://www.karollewall.com/bulbaeolidia-paulae/) - The Bulbaeolidia paulae is often confused with the Bulbaeolidia alba. It also seems to like protected lagoons and shallow algae-crusted reefs. However, unlike the latter it moves relatively smoothly across the algae, rocks and sand without the telltale jerky movement associated with the "alba." It, too, is small but is generally more than twice the - [Bulbaeolidia alba](https://www.karollewall.com/bulbaeolidia-alba/) - These tiny white Bulbaeolidia alba were all found in protected fish ponds or the shallow algae encrusted reefs of North Kihei, Maui. At first glance they appear to be just another bit of shell or algae moving in the surf as they literally jerk across the rocks and algae covered rock. On the surface they - [Shopping Cart](https://www.karollewall.com/shopping-cart/) - Aloha!

In fact 99.9% of the fish that look like this are more than likely the Forceps Butterflyfish -- a fish that is marked by a shorter, more separated nose, and a lack of black dots on a white patch behind dorsal - [Longnose Butterflyfish (Forcipiger longirostris)](https://www.karollewall.com/longnose-butterflyfish-forcipiger-longirostris/) - [Parrotfish (family Scaridae)](https://www.karollewall.com/parrotfish-family-scaridae/) - [Saddle Wrasse](https://www.karollewall.com/saddle-wrasse/) - [Old Woman or Blacktail Wrasse (Thalassoma ballieui)](https://www.karollewall.com/old-woman-or-blacktail-wrasse-thalassoma-ballieui/) - [Fourlined Wrasse (Pseudocheilinus tetrataenia)](https://www.karollewall.com/four-lined-wrasse-pseudocheilinus-tetrataenia/) - Although Fourlined Wrasses are a fairly common species on Maui, they are rarely seen -- especially by snorkelers. They are small, shy and skittish and tend to hide and dart in and out of the crevices of deeper branching coral. (to about 2.5 inches). - [Multiband or Pebbled Butterflyfish (Chaetodon multicinctus)](https://www.karollewall.com/multiband-butterflyfish/) - The Multiband or Pebbled Butterflyfish is a fairly common sight on the healthier shallow reefs off Maui. Most often they are seen as part of a monogamous pair darting in and out as they nip on coral polyps. Currently, they are not considered to be a species of concern, though higher water temperatures and severe - [Racoon Butterflyfish (Chaetodon lunula)](https://www.karollewall.com/racoon-butterflyfish-l/) - Racoon Butterflyfish are fairly common on Maui. They can be seen hanging out in large aggregations at the edge of reef drop-offs, in pairs under ledges and in caves, or as single individuals in shallow lagoons and tidepools (especially when juvenile). They have a wide range of feeding preferences, including benthic invertebrates and nudibranchs, algae - [Reticulated Butterflyfish](https://www.karollewall.com/reticulated-butterflyfish-chaetodon-reticulatus/) - Reticulated Butterflyfish are quite rare in Hawai'i, so catching a glimpse of one is always a treat. When young, they tend to hang about the same coral heads, often for months. They feed exclusively on coral and it is believed they are particularly dependent on Acropora -- a species that is easily affected by bleaching. - [Ornate Butterflyfish, Chaetodon ornatissimus](https://www.karollewall.com/ornate-butterflyfish-chaetodon-ornatissimus/) - Pairs of Ornate Butterflyfish are a fairly common sight on Maui, especially on healthy coral reefs. It's not too unusual to see small groups darting in and out of coral heads, though I personally have never seen a school of more than eight fish.. Individual juveniles can often be seen in lagoons, especially if the - [Forceps Butterflyfish (Forcipiger flavissimus)](https://www.karollewall.com/forceps-butterflyfish-forcipiger-flavissimus/) - The Forceps Butterflyfish is a fairly common sight on the reefs off Maui, though chances of seeing are far greater at Ahihi Kina'u. They seem to prefer ledges and caves and exposed reefs. Snorkelers will often see them hanging upside down beneath cliffs and sweeping over reef edges, sometimes in fairly strong surge. They feed - [Threadfin Butterflyfish (Chaetodon auriga)](https://www.karollewall.com/threadfin-butterflyfish/) - Reaching 9 inches, the Threadfin Butterflyfish is one of the larger species of butterflyfish on Maui, and one of the most common (to 9 inches). Juveniles are often seen in lagoons, fishponds and intertidal zones, while mature individuals are seen on the coastal coral reefs, as well as on sand and "pavement." They feed - [Blacklip Butterflyfish (Chaetodon kleinii)](https://www.karollewall.com/blacklip-butterflyfish-chaetodon-kleinii/) - Up until the fall of 2014, this snorkeler/photographer had never seen a Blacklip Butterflyfish on Maui. But the summer of 2014 saw a recruitment that boggled some underwater lovers' minds. Blacklips could be seen aggragating in the thousands at the edge of Molokini and in the hundreds at Ulua and Wailea beaches. It can be - [Bluestripe Butterflyfish (Chaetodon fremblii)](https://www.karollewall.com/bluestripe-butterflyfish/) - The Bluestripe Butterflyfish is endemic to Hawaii and is apparently one of the most common and of least concern (IUCN Red List). Perhaps this is the case elsewhere, especially in MPA of Papahanaumokuakea Marine National Monument, but this has not been my experience. A snorkeler is fortunate to see one of these fish on Maui, - [Lined Butterflyfish (Chaetodon lineolatus)](https://www.karollewall.com/lined-butterflyfish-chaetodon-lineolatus/) - The Lined Butterflyfish is not a common sight on Maui -- though it is more common here and on Hawaii (Big Island) than the other main Hawaiian Islands. When it is seen, it is often in surprisingly shallow water. It is the largest butterflyfish on Maui and its size and "dinner plate" shape quickly distinguishes - [Oval Butterflyfish (Chaetodon lunulatus)](https://www.karollewall.com/oval-butterflyfish/) - The Oval Butterflyfish is a fairly common sight on the healthier reefs of Maui, especially South Maui. They are most often seen in pairs, but it is not unusual to see up to 10 individuals chasing one another and darting in and out of coral heads. Juveniles are occasionally seen in lagoons and shallow reefs. - [Milletseed (Chaetodon miliaris) Endemic to Hawaii](https://www.karollewall.com/milletseed-chaetodon-miliaris-endemic-to-hawaii/) - The Milletseed Butterflyfish is endemic to the Hawaiian Islands and Johnston Atoll. It is a fairly common sight on Maui, especially on outer reefs, walls, drop-offs and ledges with strong currents. Unlike most Butterflyfish found in Hawaii, the Milletseed does not feed on coral; rather, it relies on polychaete worms, zooplanton, fish eggs and some - [Lemon or Citron Butterflyfish (Chaetodon citrinellus)](https://www.karollewall.com/lemon-or-citron-butterflyfish-chaetodon-citrinellus/) - The Lemon, Citron or Speckled Butterflyfish is an extremely rare sight on the reefs of Maui. While it is easily mistaken for a Milletseed Butterflyfish at first, closer inspection will reveal some significant differences. These fish are corallivores but they also feed on algae, benthic invertebrates and polychaete worms. The images here were taken of - [Teardrop Butterflyfish (Chaetodon unimaculatus)](https://www.karollewall.com/teardrop-butterflyfish-chaetodon-unimaculatus/) - The Teardrop Butterflyfish is always a pleasure to see. Unfortunately, on Maui, its abundance seems to be limited to marine protected areas such as Ahihi Kina'u, one of the few places in the Main Hawaiian Islands that is experiencing a growth in the coral reef. Teardrop Butterflyfish are primarily corallivores but have been known to - [Teardrop Butterflyfish](https://www.karollewall.com/teardrop-butterflyfish/) - [Goldring Surgeonfish (Ctenochaetus strigosus)](https://www.karollewall.com/gold-ring-surgeonfish/) - The only surgeonfish endemic to Hawaiian Islands, this species is fairly abundant in MPAs and healthy shallow reefs. It is also called the Goldring Bristletooth, likely due to its ability to use its teeth to scrape detritus, small crustaceans and algae from coral, rocks, and "pavement". It is not a fish seen in large schools, - [Convict Tang (Acanthurus triostegus)](https://www.karollewall.com/convict-tang-acanthurus-triostegus/) - Convict Tangs are a common sight for snorkelers and divers on Maui. Juveniles are often seen in tide pools and lagoons and large schools are often seen feeding at the edge of shallow reefs, lagoons and wave swept habitats. Like all surgeonfish, Convict Tangs play a major role in keeping the reefs healthy by cleaning - [Saddleback Butterflyfish (Chaetadon ephippium)](https://www.karollewall.com/saddleback-butteflyfish-chaetadon-ephippium/) - Saddleback Butterflyfish are a rare but beautiful sight on Maui. They can surprise a snorkeler or diver by suddenly popping their heads up over a high coral reef or emerging from a silty fishpond. They feed on everything from coral polyps, small crustaceans and invertebrates, to algae. They can be quite skittish and usually travel - [Racoon Butterflyfish (Chaetodon lunula)](https://www.karollewall.com/racoon-butterflyfish-chaetodon-lunula/) - [Bullethead Parrotfish, Female & Juvenile](https://www.karollewall.com/bullethead-parrotfish-female-juvenile/) - [Bullethead Parrotfish, Male](https://www.karollewall.com/bullethead-parrotfish-male/) - [Stareye Parrotfish, Female](https://www.karollewall.com/stareye-parrotfish-female/) - [Male Stareye Parrotfish](https://www.karollewall.com/male-stareye-parrotfish/) - [Male Spectacled Parrotfish](https://www.karollewall.com/male-spectacled-parrotfish/) - [Male Ember or Redlip Parrotfish](https://www.karollewall.com/male-ember-or-redlip-parrotfish/) - [Female & Juvenile Ember or Redlip Parrotfish](https://www.karollewall.com/female-juvenile-ember-or-redlip-parrotfish/) - [Parrotfish title](https://www.karollewall.com/parrotfish-title/) - [Parrotfish title](https://www.karollewall.com/parrotfish-title-2/) - [Spectacled Parrotfish (Chlorurus perspicillatus)](https://www.karollewall.com/spectacled-parrotfish/) - ENDEMIC to Hawaii. Like all parrotfish, Spectacled Parrotfish begin life (their initial phase -IP) as females. Only a select few will transform into males (terminal phase TP), and even fewer into supermales. Unlike some species of parrotfish that are found in large schools, the Spectacled is generally observed as - [Parrotfishes (scaridae) or UHU in Hawaiian.](https://www.karollewall.com/parrotfishes/) - Click on the image of the Spectacled Parrotfish below and you will be taken to galleries that include the most commonly seen Parrotfish on Maui.
