Glossodoris cruenta from Solomon Ids

Dear Bill,
I was diving recently [April 2003] on a small boat wreck on the outskirts of Honiara, Solomon Islands when my dive buddy found this Glossodoris cruenta

It would have been about 45mm long, and at about 12 meters deep. This is not a common slug in these parts.

Thanks Bruce,
This doesn't seem to be a common species anywhere - which brings up the question of why some species are common and some are apparently rare. I'm afraid I don't know if there is an answer to that question but it is a useful way to get a discussion going.

I must say this animal is much more orange than usual, but I see an earlier photo you sent is of an animal almost intermediate in colour between the normal yellow colour form and this orange one.
Best wishes,
Bill Rudman
