Favorinus branchialis from the Mediterranean

From: Sylvie Grall

Dear Bill,
I just don't know this species I found in the Etang de Thau (April 2004).  I found 2 individuals crawling on the muddy bottom (size = 20 mm)

Locality: Etang de Thau. France. Mediterranean. Depth: 5 m. Length: 20 mm. 2 April 2005. Pillars. Photographer: Sylvie Grall.

Thank you for your help.
Sylvie.

Dear Sylvie,
This is Favorinus branchialis. Species of Favorinus are interesting because they feed almost exclusively on the eggs of other sea slugs. Some species, such as F. branchialis, change colour as they move from one egg ribbon to another, the colour of the digestive gland in their cerata changing as the colour of the eggs they are eating changes.
Best wishes,
Bill Rudman
