Concerning message #20026:

Dear Dominique, dear Bill,

I've just taken a picture of an "unidentified" nudibranch. It seems to be a Janolus cristatus too. Compared to the first picture of Dominique, one can see the same pale orange body and the blue extremities. Moreover, it has the same two white lines on the top of the body.

I didn't found any other Janolus during the dive, same colour or another.
The pictures were shot during a dive called "La Pierre à Mouret", south of Les Embiez (France) at approximately 32m on 5th august 2007 (~9:30am) departing from Sanary-sur-Mer with the Club de Plongée de Sanary (www.sanary-plongee.com ).

Locality: La Pierre à Mouret, 32m, Les Embiez (France), Mediterranean Sea, 05 August 2007. Length: approx. 30mm. Photographer: Raphaël Vallotton.

Thanks for sharing your shots.
Best regards.
Raphaël
