Flabellina bilas maybe? from the Red Sea

August 11, 2007
From: Oren Lederman


Hi Bill,

Attached are 3 photos showing two different specimens of a species I couldn't identify. Binyamin Koretz suggested it's a Flabellina bilas.

, ~6 meters, Israel, Red Sea, 11 May 2007. Length: ~5 mm. Photographer: Oren Lederman.

Can you help identify it?

Dear Oren,
I am beginning to wonder now whether Insian ocean animals [messages #10243, #6224] are in fact correctly identified as C. bilas. Overall they look quite like the Pacific F. bilas but the banding on the cerata is not quite the same. Your animals here may be a lighter version of the same thing or perhaps a speckled version of F. bicolor. I see I have identified an earlier find of this animal by Binyamin as F. bicolor [#15504]. I'm afraid there is only so far we can go with photos - this is a case where the animals will need to be looked at internally. For the moment I will tentatively identify it as F. bicolor.

Best wishes,
Bill Rudman
