Okinawan Ceratophyllidia

Hi Bill,
Here is a photo of an Okinawan Ceratophyllidia (africana?) which is very similar to both Valda's recent post of a Ceratophyllidia africana in the Forum and that is seen in Terry's Nudibranchs of South Africa.

The animal was found crawling on the surface of a small patch of open sand in an area of strewn coral rubble. This is the only one I've seen here and it has been deposited with the Calif. Acad. Sciences. Quite a range extension if this is C. africana.

Data: RFB # 3378., TL: 32mm., Collection Depth: 50m (165ft)., Seragaki, Okinawa, 15 March 1995.

Cheers,
Bob

Dear Bob,
Another interesting find. Its background yellow colour looks like Valda's South African photo and the change in colour of the cerata is identical to that seen in Walabha's photo of a 'green' animal from Indonesia.
Best wishes,
Bill Rudman
