Goniodoris sp. (undescribed)
Well here is another new one I have not seen anywhere. Gorgeous little thing. And little is right - maybe 5mm in length. Great eyes Jim.
The family Goniodorididae is a confusing group related to Onchidoridiade. Both are more closely related to cryptobranchs than to other phanerobranchs, due to the morphology of the radula and buccal pump. Hard to say is this this species is a Goniodoris or if it belongs to the genus Goniodoriella. I am placing it here as a Goniodoris because it does not have smooth rhinophores, nor elongate extra-branchial appendages.
Like other members of the family this species has a well-developed notal ridge, which forms a lobe shaped extra-branchial appendage to each side of the reduced gill. The color sets it apart from all species in published field guides today. Yellow specks cover the body, with reddish maroon specks forming a marginal band on the notal ridge and a stripe down the tail. The rhinophores are black at the tips, as are the head tentacles. This coloration is somewhat similar to white colored Goniodoris sp 2 in Indo-Pacific Nudibranchs.
Nice find Jim, we will add it to the next edition.

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!
