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

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

Best wishes,
