Dear Bill,

These two individuals come closest to Dermatobranchus ornatus from the samples on the forum but not quite. Can you please confirm ?

Locality: Beach, 12 meters, East Timor, Banda Sea, 08 April 2006, Near shore. Length: 30mm. Photographer: Nick Hobgood.

Dear Nick,
Yes this is Dermatobranchus ornatus. It is one of the few species of the genus in which the mantle is lacking longituninal ridges. I hadn't realised until know just how similar in colour and shape this species is to a soft-coral colony. Each of the tubercles could be mistaken for a half extended soft-coral polyp.

Best wishes,
Bill Rudman
