Eubranchus doriae from French Mediterranean

July 30, 2003
From: Marina Poddubetskaia

Dear Bill,
During one dive in Cerbere I collected a branch of Aglaophenia with Doto floridicola egg-ribbon on it [lower right photo] and a tiny animal which I believed to be Doto. You could imagine my astonishment when I saw in laboratory that this animal was Eubranchus and not Doto !

Here are some photos of it. I think it is Eubranchus doriae. Could you confirm this ID, please ? I kept this Aglaophenia several days in the tank and Eubranchus has never been outside it. And yet it doesn't seem to be its food ?! Moreover, in the lower right photo you can see some small eggs near the larger Doto floridicola egg-ribbon. I didn't see them at the beginning, so I believe they were laid by Eubranchus in the tank.

Dear Marina,
I agree this is most probably Eubranchus doriae. I first thought the eggs just above the Doto egg ribbon were part of that ribbon but the eggs are definitely about twice the diameter of the Doto eggs. Definitely an interesting observation
Best wishes,
Bill Rudman
