This single specimen where found on the West coast of Norway, among a huge crowd of mating sea hares. As I was too far away from home to bring Jussi Evertsen a sample. I have never seen anything like it. Do you know what it is?

Locality: Hordaland, Norway. North East Atlantic. Depth: 19 meters. Length: 15 mm. 11 July 2005. very exposed reefs, hard bottom. Photographer: Kåre Telnes

Dear Kåre,
Even from so far away, I am sure your animal is a juvenile Sea Hare. From the way the parapodia are joined at the back I would guess it isAplysia punctata . In juvenile aplysiids the shell is much more exposed than in adults, but it has its characteristic flattened shape. The sperm groove running from the front of the mantle cavity/shell down the right side to the near the front of the head is a sure sign of an aplysiid, as are the four head tentacles. See the Fact Sheet on the aplysiid head for comparision.
Best wishes,
Bill Rudman
