Concerning message #13997:
Regarding the unknown Janolus...
There are 3 described Caribbean species, of which "Caribbean Sea Slugs " recognizes 2 of them.
Janolus comis: gray with opaque white spots; cerate swollen with small tubercles; posterior end elongate; rhinophores irregularly lamellate.
J. costacubensis is considered a synonym of J. comis by this publication.
Janolus mucloc: Translucent with a white band down the midline; rhinophores lamellate with white tips; elongate, swollen cerata with white lines along their length and orange subapical spots and clear tips.
This species seems to be similar to J. mucloc (white mid-line band and white tips on rhinophores) but differs in having a much different ceratal pattern (yellow rings with a bordering orange band) and more inflated cerata (as opposed to elongate and pointed). I'd say it was an undescribed species until we get our hands on a specimen.
Thanks for your time,
Ray

I agree. That's why I put it on the Forum 2 years ago as Janolus sp. 7.

Dear Vlad,
From its general shape, this is a species of Janolus. [See Janolus barbarensis from the Pacific coast of Nth America] if you look carefully between the blue and white rhinophores there is a large orange swelling or caruncle which is charcteristic of these animals. In the close-up of the cerata alongside you can see in a few cases, a pair of brown ducts inside each ceras, which are ducts of the digestive gland.
As to a name. As far as I know it doesn't seem to fit any of the species of Janolus, or related nudibranchs, which have been described from the western Atlantic, or for that matter the eastern Atlantic. If anyone recognises it can they please let me know.
Best wishes,
Bill Rudman
