Hi Bill,
Thanks for your quick response [#14920]. I do have another photo of the Chromodoris. Unfortunately it is not a good one, but I do think it might have its mouth extended, but whether it is feeding on the sponge or on something in the sand, I don't know.

Locality: Sodwana Bay, South Africa, Indian Ocean coast. Depth: 9 meters.
Length: 4 cm 3 October 2005. Algae/sponge reef. Photographer: Colin Ogden

Also can the photo give more info about the sponge?
I hope this helps
regards
Colin

Dear Colin,
The quick response was because I am trying to finish a manuscript and evrytime I do, I get sent a new tantalising addition. Your photo doesn't show the sponge any better but it does show the buccal bulb extended, indicative of feeding. As I said earlier, I have been pretty sure that C. mandapamensis is a spotted from of  C. striatella, but your photo may suggest differently. The only records I have of C. striatella feeding, are some observations of my own of it on species of Darwinella. I am pretty sure your orange sponge is from a quite unrelated family, which would suggest the two chromodorids are different. What I need now is some more observations of both the species feeding to confirm these differences. As I said earlier - a very tantalising find.
Best wishes,
Bill Rudman
