Possibly Caliphyllidae species.

From: Haruo Kinoshita


Dear Bill,
I recently went to Izu Ocean Park, Japan and found the attached animal. I found two individuals at different dive site at February 7 and 8. As for my observation of living animal, dosal papillae was just like sea-squirt. I am feeling that this is possibly one of Caliphyllidae but I can't identify further more.

Dear Haruo,
I am not sure what this is. As you say, it could be a sacoglossan like Cyerce, but the rhinophores seem to have swellings on them like an aeolid nudibranch. Without some more information this is a bit of a mystery.
Best wishes,
Bill Rudman
