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 fishpond in Nth Kihei in the fall/winter of 23/24. The smaller, brighter animal was under a ledge at Makena Landing in a surge zone and is likely a juvenile — only a few mm — apologies for the blurred image, but it was the first one known to be documented in Hawaii, and it deserves a place in history.  The mature individuals were approximately 10 mm or less than 1/2 inch.  An added treat:  Pam Madden has an excellent video of this species that she documented in a tidepool off the Big Island.
