Concerning message #22718:

Dear Bill,
Following on from the discussion of Chromodoris elisabethina colouration and food here are some photos from North Solitary Island of one with strong colours near a red sponge. As it moved on the surge pushed its rhinophores so you can clearly see the anus amongst the gills. There was also a Chromodoris magnifica about a metre away. Hope this is of interest you didn't have one from the Solitary Islands and this is the second time we have seen one in this area.

Locality: Elbow Cave, North Solitary Island, Solitary Islands Marine Park, 12 metres, New South Wales, Australia, Pacific Ocean, 23 December 2008, Coral Reef. Length: approximately 30 mm. Photographer: David and Leanne Atkinson.

Regards,
Leanne & David Atkinson

Dear David and Leanne,

Thanks for the photos. Red backgrounds can be deceptive as they are often coralline algae, but this is one of those mixed bottoms with sponge colonies as well. Very tantalising. The only sign of feeding I can see are the whitish tangled grooves on the pink coralline algae which I suspect are the feeding tracks of some herbivorous snail.

If you have a photo of your C. magnifica from Solitary Islands it would be an interesting addition because I can't recall a record from that far south.

Best wishes,
Bill Rudman
