Hypselodoris festiva feeding

Hi Bill,
I just looked out these pictures of Hypselodoris festiva from Hong Kong, April 1983.

In the second picture you can see an animal which is feeding on what appears to be a keratose sponge. I've noticed that this type of sponge is often eaten by chromodorids, the sponge tissue seems to be taken leaving the spongin skeleton behind.

Thanks Bernard,
From my experience most chromodorids feed on keratose or other sponges without a spiculate skeleton. Unfortunately many references in the literature which suggest otherwise seem to be based on poor sponge identifications.
Cheers,
