Dear Bill,
I saw Marina Poddubetskaia' message [#12254] about Elysia tuca from the Southern Bahamas and thought it looked quite like this Elysia from Japan. Is that possible from the viewpoint of distribution?
I would be very happy if I could hear your comment.

Date: 17 Jan 2004
place: Amami-Ooshima Islands, Kagoshima, Japan.
size: approx 15mm
depth: 3 m
temperature: 21 C

Best Regards,
Jun Imamoto

Dear Jun,
Although there is a slight similarity in colour pattern I don't think your animal is related to E. tuca. As you indicate. it certainly would not be a 'natural' distribution for a species to occur in Japan and the Caribbean. Probably of more importance than the colour differences is the probable food of each species. Elysia tuca feeds on the the calcified green algae Halimeda. I am not sure what your animals feeds on, but if it is the algae in your photo it certainly does not seem to be a species of Halimeda.

I have had a quick look through the literature but can't find a species matching the colour of your animal. Perhaps Kathe Jensen will recognise it.
Best wishes
Bill Rudman
