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 found in North Kihei/Ma’alaea Bay or Makena Landing, Maui.  They have various common names and the most popular world-wide seems to be the “Caramel Nudibranch” for obvious reasons.  Sea Slugs of Hawaii provides more information and photos, including a very light version (almost white).
