I suspect these are Platydoris striata. Ii found them on a night dive trailing on a sandy bottom. They seem to be shy animals as they disappeared in a small crevice escaping my dive and strobe lights. There are only 3 postings for this species on the Forum, is this an indication that these animals are rarely seen ?

This is what I have always called P. striata, but a recent publication has considered that species to be a colour form of the red-spotted P. cruenta [see my comments #20542 on why I think we should at least at present retain P. striata].
It's interesting to see another opisthobranch 'trailing'. What appeared to be chromodorid behaviour seems to be quite widespread. Concerning how rare they are, it's a bit hard to say. A lot of these large 'flat dorids' are not that commonly seen. Personally I think they are much more abundant than we think but they are extremely well camouflaged and are often found in loose coral rubble and areas with lots of cracks and crevices. It is surprising how they can squeeze and distort their bodies to fit into seemingly impossible spaces, including the middle of a dead Acropora skeleton. I think we probably just don't see most of them.
