Dear Bill,
These photos were taken at Moon Islet, CheJu Is, South Korea. I suspect that this is Flabellina bicolor. Can you tell me if this is true and more information.

Dear Dong Bum,
I have included one of your 27 October 2002 photos here. I suspect that we may be mixing more than one species into what we are calling Flabellina bicolor. Your animals seems to have a distinct edge to the mantle, forming a white line down each side between the ceratal clumps. The oral tentacles seem to be a lot shorter and don't seem to form the white terminal 'paddles' seen in more typical examples of the species. Also there seem to be many more rows of cerata than usual. It would be helpful to know what the rhinophores look like more clearly. Are they lamellate? In many ways it reminds me of the Mediterranean Flabellina babai
Best wishes,
Bill Rudman
