Wow what a beautiful and complicated aeolid nudibranch. Members of this family are characterized with the curious, highly private, I would think, position of their anus. I am not sure I would feel comfortable about someone characterizing me about the location of my dernier, although it is most likely the same as yours.
Internally the radula is characteristic also - a single row of rachidian teeth with long basal limbs and a large pointed cusp flanked by several denticles.
The body has irregular red longitudinal lines along the edge. Opaque white spots cover the body, head, oral tentacles and rhinophores. The bases of the brown cerata have black dashes. Their tips are white. Very cool.
This one is new to me. Thanks Jim.

Jim's photography has been featured in a number of books and publications including Helmut Debelius' Nudibranchs and Sea Snails of Gosliner, Behrens and Williams Coral Reef Animals of the Indo-Pacific. A photo of Jim petting a shark in "Sleeping Shark Caves" off Isla Mujeres Island, Mexico, taken by Amy Foster his significant other, recently appeared in Dave Behrens' Diving Guide to Cozumel, Cancun & The Riviera Maja.
Jim has also been a major contributor to (1) the New Indo-Pacific Nudibranch and Sea Slug Identification book by Gosliner, Valdez, Behrens (NSSI),(2) Tropical Pacific Reef Creature Identification by Humann & DeLoach,(3) Nudibranchs Encyclopedia by Neville Coleman,(4) Reef Fishes of the East Indies by Gerald Allen and Mark Erdmann, And many other publications.
Jim has been a solid supporter of the Slug Site since day one. His countless contributions put him near the top of the list of photographers who have greatly expanded our knowledge of sea slugs. There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!

This new 2nd Edition is updated and reorganized, including 185 new species. Among other features, the new edition includes additional photographs of species, an identification key, and an up-to-date classification reflecting the latest evolutionary relationships. The Indo-Pacific represents the largest expanse of tropical ocean in the world, stretching from the Indian Ocean coast of southern Africa and the Red Sea to the central Pacific of the Hawaiian Islands, Easter Island and the Marquesas.
This region supports the most diverse marine fauna of any place in the world for most groups of marine organisms. The nudibranchs and sea slugs are no exception to this rule; there are about 3,000 described species of these organisms in the world and at least 40% of these have been found exclusively in the Indo-Pacific tropics. This book illustrates 2,138 Indo-Pacific nudibranchs and sea slugs, including many undescribed species.
