Chromodoris britoi from French Mediterranean

August 29, 2008
From: Dominique Horst

Hi Bill,

I think this is Chromodoris britoi.  We found it on the sand and mud during our last night dive and its beautiful colours appeared in the light. It was very stressed because it was being attacked by a small worm and crustaceans. I suppose the light was attractive for these small animals.

Locality: Cagnes, 6 m, France, Mediterranean sea, 27/08/2008. Length: 10 mm. Photographer: Dominique Horst.

After a few minutes the dorid seems to "jump" in the current to move away. It's not the first time I've observed this behaviour.

Kind regards,
Dom.

Dear Dom,

Thanks for the interesting behavioural note. Certainly in the upper photo it looks as though some animal has crawled up under the mantle and is clearly 'annoying' the chromodorid. Lifting its mantle skirt up like this could easily allow it to catch a current and drift away.

Angel Valdes [message #3157] suspects that this species and the Caribbean Chromodoris binza are probably the same.

Best wishes,
Bill Rudman
