Platydoris sabulosa from Queensland

Hi Bill
Thought you might be interested in a critter I found Saturday [2 June 2007] on the Sunshine Coast, Australia, at a dive site called Old Woman Island near Mooloolaba in 14 m of water from under a rock. It was 140 mm long.

Richard Willan identified it for me as Platydoris sabulosa  It will be preserved for the Museum of Darwin's wet collection. I knew nothing of it until now. I think this is a great find!

Dear Gary,

Yes this is an interesting find. Terry Gosliner has confirmed the identification and so it certainly helps clarify the external features of this species for me. I had wondered before if this species was Platydoris noumeae Risbec, 1928 but Dorgan, Valdes & Gosliner (2002) looked at the holotype of that species and considered it to be a synonym of P. scabra - which certainly fits Risbec's specific description of yellow rhinophores. It's good to add another species to the Forum

Best wishes,
Bill Rudman
