Trippa intecta from New South Wales

Hi Bill

Took this photo of a nudibranch that I've never seen before. Could you help me in identifying it? I've tried the WA, Coleman and Debelius books, and can't find anything (although I may not be looking hard enough).

The slug was seen on the SE-corner wall of Martin Island, off Wollongong, New South Wales, 6 August 1999, in a depth of 25m. Time of day was about 9.00am, water temp was 16C, and visibiliy was about 8-10m.

Appreciate your assistance.

Best regards

Dear Des,
This is Trippa intecta. One reason its hard to find in books is that it is very difficult to photograph, the dark brown colour making it a photographer's curse and a photographic shopkeeper's dream.

The photograph I have put at the top of the page is slightly overexposed, which allows you to see some of the detail of the animal's shape. Trippa intecta is essentially a tropical animal so finding it in the warm temperate waters of Wollongong, New South Wales, far south of the tropics is unusual, but reflects the ability of planktonic larvae to travel considerable distances, and survive, if the physical conditions are favourable.
Best wishes,
Bill Rudman.
