Hello Bill,

More chromodorid feeding photos for you. I observed these two Chromodoris clenchi "munching away" on this purple sponge. When they moved away, you can see the area where they had eaten the sponge.

Locality: West Palm Beach,  15 feet, Florida USA, Atlantic Ocean, August 16, 2007. Length: Appx 8 mm each. Photographer: Anne DuPont.

Thanks again for the Forum.

Dear Anne,

Thanks for this valuable observation - which I think is the first feeding record for this species. My guess is that this sponge is as a species of Chelonaplysilla - a Caribbean counterpart to the Indo-West Pacific C. violacea, perhaps. Species of Chelonaplysilla are unique within the Darwinellidae in having sand grains incorporated in their skeleton, which gives them a rough sand-papery feel.

Best wishes,
Bill Rudman
