Chromodoris striatella - feeding

April 3, 2003
From: Bill Rudman

To accompany Erwin's message concerning Chromodoris striatella, here are close-ups of two of his photos to show feeding scars on the sponge colony, which I am sure indicate that this animal is feeding on this sponge.

In the upper photo there is a patch right above the animal, in which the sponge layer has been removed. I would assume from the salloped edge that this has been caused by rasping of the radula. In the lower photo the same patch is mostly obscured by the animal but some of it is visible below the right rhinophore.

Data: Philippines, Malapascua Island, divesite "Gato Cave". Size: 28mm. 22 February 2003. Depth: 17 m. Photos: Erwin Koehler.

Best wishes,
Bill Rudman.
