Glossodoris rufomarginata from Japan

September 8, 2001
From: Toshihiro Horiuchi

Dear Bill,
I found this animal at Arasaki, Miura Peninsula, Japan. It had adhered to the sponge on a rock with a depth of 0.5m. Water temperature is 25 degrees and a size is about 20mm.

Mr.Satoru Hori who is my friend also by chance had found the same spacies in Miura Peninsula. I looked looked in the seaslug guide books which I own, and on Internet sites, but was unable to find the same species. I think it is perhaps a species of Chromodorididae. Could you help me to identify this?
Best regards,
Toshihiro Horiuchi

Dear Toshihiro,
This is a colour form of Glossodoris rufomarginata. As you will see on the Forum it is quite variable in colour. If by chance you photographed it on the sponge on which you found it, it would be nice to have a photo of it with the sponge as it might give us a clue to its food.
Best wishes,
Bill Rudman
