Discodoris atromaculata from Greece

March 19, 2002
From: Fons Sarneel


Dear Bill,
Last year, [31 August 2001], my wife and I were diving near the island Crete, Greece. To be specific, we were at the coast of the isle "Dia", which is an uninhabited "rock" close to the north coast of Crete.

There we saw these slugs (?). I suppose they're known species. We found them at a depth of somewhere between 15 and 25 meters.
Yours sincerely,
Fons Sarneel

Dear Fons,
Thanks for this photo and the other which I'll post separately. This is Discodoris atromaculata which is a fairly common Mediterranean species, often found on its food sponge Petrosia ficiformis. I presume the sponge in your photo is that species. It seems to range in colour from this purple form to an off-white.

In an earlier message there is a photo of a darker form of this slug from Greece. I discuss there an idea that had been proposed suggesting that eastern populations of this species in the Mediterranean were darker than those at the western end. Your animals are as 'white' as any I have seen from the western Mediterranean so they certainly don't fit the theory.
Best wishes,
Bill Rudman
