Thordisa villosa? from Nelson Bay

March 14, 2003
From: Dave Harasti

Hi Bill,
I have attached a couple of images that were all taken at night at Fly Point, Nelson Bay NSW, Australia.

I think they are all colour variations of Doriopsilla peculiaris. The unusual thing with this animal is that I have never seen one during the day but when ever I do a night dive at Fly Point they appear to be common! Defnitely a nocturnal species in my view.

Regards,
Dave Harasti

Dear Dave,
I have put the other two photos in a separate message because they are most probably D. peculiaris. This animal though is most probably Thordisa villosa. If you look carefully you can see the tapering papillae on its back. It's not usually so orange in colour but we have a message on the Forum from Ron Greer with a very similar looking animal.
Best wishes,
Bill Rudman
