Flabellina affinis from the French Mediterranean sea

August 16, 2007
From: Dominique Horst

Hello,

As the body of this Flabellina affinis is rather transparent, a white bean is visible in the central position. Could this be the heart or any digestive gland ?

Locality: Cap d'Antibes, 12m, France, Mediterranean sea, 08 July 2007. Length: 25mm. Photographer: Dominique Horst.

Kind regards,
Dominique

Dear Dom,
The only structure I know that gets this opaque white appearance is the ampullar region of the reproductive system where the animal's sperm is stored. It is only noticeable like this when the animal is mature and the ampulla packed full of sperm.

Best wishes,
Bill Rudman
