Hypselodoris fontandraui ? from mediterranean France

August 6, 2007
From: Laurent Urios

Hi !
I took these pics last month near Collioure (France - Mediterranean Sea) at 10 m depth. I'm sorry for the bad quality. Can you tell me if all are Hypselodoris fontandraui? I have doubts because of the smallest ones that have points along the line that makes me think of H. tricolor. And concerning the lonely one on the other photo, the pattern doesn't seem to be like the ones I have seen in books and on your website (congratulations for this great source of information !).

Locality: Collioure, 10 m, France, Mediterranean Sea, 12 June 2007, rocky coast. Length: between 2 and 3 cm. Photographer: Laurent Urios.

Thank you.
Laurent.

Dear Laurent,

I am pretty sure these are all Hypselodoris fontandraui. They seem to be feeding on the dirty yellow sponge which has bundles of fibres sticking out of conical outgrowths on the colony. This species is reported to feed on Dysidea avara, which looks nothing like this. It is possibly a dying colony but I will have to check with a sponge expert.  The egg ribbon is rather tantalising but its not possible to say if these slugs are responsible for it.

Best wishes,
Bill Rudman
