Goniobranchus sp. 45 (Undescribed)
Well it's time to begin the next 1000 Nudibranchs of the Week. Here you go Mike, number 1001. Externally, this group of undescribed Goniobranchus certainly doesn't look like chromodorids, but their internal anatomy gives their identification away. We have included three of these unique species on page 231 of Nudibranch and Sea Slug Identification . All three are cryptic on the sponges they feed on. Our species here has a granular texture suggesting sponge oscula, with several high tubercles. The rhinophores have a give-away red-orange band. Jim's specimen here has a few flecks of the same color on the tips of the gill and on the notum. Recall that in the revision of the chromodorids, this genus was separated on the fact that the egg ribbon is a vertical coil attached to the substrate by its edge, rather than flat to the substrate

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 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!
