Janolus sp. 2 (undescribed)
This species has been in Terry Gosliner's to be described bucket for years. Hard to say if it will ever surface, with so many new species being discovered weekly. We refer to it as Janolus sp. 2 in Indo-Pacific Nudibranchs and Sea Slugs.
The body and cerata are cream colored. The cerata have two sub-apical bands - the first is deep purple-blue followed by a light blue band. The tip is yellow-orange.
Jim Black's photo shows amazing detail of the rhinophores and the caruncle, between them. You can clearly see the folded gland within the caruncle suspected of having a sensory function. We still are not sure what the actual function is.
Riding on the head of this particular critter is the commensal shrimp, Periclimenes imperator. Most commensal shrimp stick to a single host species, but P. imperator seems not to discriminate, being commonly found hitch-hiking on various opisthobranch species as well as echinoderms.

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! As an added note, Jim was one of the keynote speakers at the Pittsburgh Scubapalooza, held Saturday, 5/14 at the Pittsburgh Scuba Center, 818 Ann St., Homestead, Pa. Send Jim email at jim.black14@verizon.net WEBMASTER'S NOTES : Another great submission by Jim Black who continues to astound us with his uncanny ability to find and photograph slug images most of us probably aren't going to see in this lifetime!
