Dear Bill

A friend give me this pictures. First, I believed it's a Discodoris sp. but I don't see the same spines on the mantle in the forum.
Thanks for your answer and for the forum.

Dear Jean-François,

This is almost certainly a species of Thordisa. I have previously identified animals such as this as T. villosa, but a recent publication suggests there are quite a few different species. Until I have time to digest this study by Chan & Gosliner, I can't say what species it is.

Best wishes
