Hypselodoris carnea at Fly Point

It certainly looks quite like photos I have seen of Hypselodoris carnea. The main colour difference appears to be that the orange-brown lines in your photo are distinct spots in Indian Ocean specimens. Also the border around the anterior end of the mantle in Indian Ocean specimens is an unbroken bluish line, while in your Port Stephens animal there is a row of purplish spots around the mantle edge. These differences may not necessarily be of significance but I would need to have a look at the anatomy of a specimen, including its reproductive system and the shape of its radular teeth, before I could confirm its identity. From the photo I can't even be sure it is a species of Hypselodoris. It could equally be a Chromodoris. Whatever it is it is very interesting and something I have not seen in eastern Australia before...Bill Rudman
