Re: Flabellina affinis? from French Mediterranean

Dear Bill,
Thank you for your response. To my knowledge, cerata in Flabellina affinis don't join the body directly. Usually, cerata are put together into 'trunks'. But in my animal it isn't so. Is it different in juveniles ?
Best wishes,
Marina.

Dear Marina,
Identifying juveniles is always difficult and often involves a degree of guesswork. Adults of both F. affinis and Flabellina ischitana have the cerata arising from a common stalk. As I said in my earlier message I can't see the characteristic lamellae on the rhinophores either. On the basis that it is a purple Flabellina from the Mediterranean, and has purple dusting on the cerata, my best guess is that it is a juvenile Flabellina affinis. Sometimes there is not much to be gained debating the identity of the unidentifiable. If you had the specimen and its identity could be confirmed by looking at its anatomy, then the photo could give us an idea as to what a juvenile of that species looks like. But since we can't positively identify it, we can't really say much else.
Cheers,
Bill Rudman
