Chromodoris annae on sponge

From: Roberto Sozzani

Dear Bill,
I found another photo of Chromodoris annae on sponge from Manado (Indonesia), shot in November 2003.
This time, a C. dianae is in the background sharing the same sponge.

Best regards

Thanks Roberto,
From this photo I am pretty sure the unidentified animal in your earlier message is C. annae. I also suspect this sponge is the same species as the one in that message. It is interesting how C. annae and C. elisabethina on these dark grey black sponges have very dull orange pigmentation - in fact they lack the orange pigmentation. It certainly makes them better mimics of the species without an orange border. Perhaps the pigment they require is not available in this group of sponges. We are not sure whether essential pigments are obtained from their food but it is an interesting hypothesis
Best wishes
Bill Rudman
