Chromodoris tinctoria feeding

Hi Bill,
Here are photo`s of three different animals which I have id as Chromodoris tinctoria. All three are similar to the ones in Dave Harasti`s message #8248. I found these animals on the same type of sponge at three different locations around Flat rock (they all appear to be having a good munch).

Locality: Flat Rock North Stradbroke Island, 16-24 m, Queensland Australia, Pacific ocean, 29 December 2005, 24th April 2006, 3rd June 2006. rocky reef with sponges, hard & soft corals . Length: approx 35 mm. Photographer: Bruce Wilkie.

Could you please confirm these are C. tinctoria?
Many Thanks,
Bruce Wilkie.

Dear Bruce,
Very interesting! Three records of this species on the same sponge, and definitely signs of damage in upper right photo. All I need to do now is confirm the sponge's identity. I have been considering this 'form' to be part of one very variable species - C. tinctoria, and their seem to be no easily distinguishable anatomical characters. However it would be valuable to learn a bit more anout this species and its various colour forms so I would welcome photos of egg ribbons and other sponges it has been found feeding on - if anyone has any.
Best wishes,
Bill Rudman
