Dear Bill
I found this nudibranch on the outer reef flat at Heron Island in April of this year. I looked through your forum and several books and have been unable to identify it. I would greatly appreciate your help in determining its identrity.
Locality: Heron Island, 20cm, Intertidal, Australia, Pacific ocean, 18 April 2006, Intertidal reef flat. Length: 4cm. Photographer: Simon David Power.
Many thanks,
David

This is Roboastra gracilis, which feeds on other nudibranchs - mainly its close relatives, species of Tambja.
Best wishes,
Bill Rudman
