Dear Bill and Nishina,
I am glad the old eyes can still spot a sacoglossan. However, I do not feel comfortable about assigning it to either Aplysiopsis or Hermaea. I guess this is another one who needs to have its teeth examined. Aplysiopsis has very characteristic "sabot-shaped" teeth with coarse denticles (sabot means a dutch wooden shoe - like those of Santa Claus), whereas Hermaea usually has blade-shaped teeth, sometimes with fine lateral denticles.

If this animal had had some large cerata, it might have been possible to see a branching vessel on the inner surface of the cerata. These vessels correspond to those seen in Elysia and connect to the pericardium.
Cheers,
Kathe

Thanks Kathe,
I think to be safe I will call it hermaeid sp. 1.
Cheers,
