Hi Bill,
We found these Thecacera pennigera mating. They seem to be on their food. Thought these shots might be of interest. Water Temperature: 19 degrees celcius

Locality: Fly Point Marine Reserve Port Stephens , 10 metres, NSW Australia, Pacific, 12th November 2006, Sandy bottom with scattered sponges, ascidians, bryzoans soft corals and gorgonians.. Length: 15 to 20 mm. Photographer: Leanne & David Atkinson.

Regards,
Leanne & David Atkinson

Dear Leanne & David,
Thanks for these interesting photos. The Thecacera certainly are on an arborescent bryozoan which is almost certainly their food. It is interesting to see two animals with this small-spotted pattern. The small-spotted pattern is the typical Atlantic colour form while in the Pacific larger spots seem more common.

Best wishes,
Bill Rudman
