Hi Bill

I am hoping you can find a little time to help me id this slug ? i have had a good look through the forum but can't quite seem to match it up.

Locality: Kapalai island, 11 meters, Sabah, Borneo, Celebes Sea, 14 March 2008, Sheltered reef. Length: around 5 mm. Photographer: Richard Swann.

I guess it is some kind of Flabellina but i am just not sure.

Thanks for your help
Kind regards
Richard

Dear Richard,
I have the nagging feeling I have seen this before but I can't remember where. The proportionally huge rhinophores suggest this is a juvenile of a species which grows quite a bit larger than 5 mm but I can't get enough clues from the photo to guess a family. The only think that looks familar is the colour of the head and rhinophores which remind me of the orange colour form of Cuthona yamasui.

If anyone has any ideas they would be very welcome

Best wishes,
Bill Rudman
