Dear Bill,
I found this photo of a Chromodoris dianae feeding on something that is not a sponge.

Locality: Gangga Is. Indonesia. Depth: 12 metres. Length: 4 cm. August 2004. muddy slope. Photographer: Roberto Sozzani

I hope this can be helpful for the Forum.

Best wishes

Dear Roberto,
Although I like new discoveries, I would have found a chromodorid feeding on something other than sponges to be a disturbing concept. However looking at your photo close-up I am sure the chromodorid is not feeding on the branching object it is on. I suspect the object is a dead part of the hydroid colony which fills the bottom half of the upper photo. If you look at the head, in the close-up, the mouth is visible between the two pointed oral tentacles and there is no sign of eversion of the buccal bulb or oral tube. The white piece in contact with the dead hydroid branch is thw anterior part of the foot.
Best wishes,
Bill Rudman
