Diaulula sandiegensis food sponge

Hi Bill,
Sorry I didn't include it in my first message: the orange finger sponge is listed in Gotshall's book Guide To Marine Invertebrates as Neoesperiopsis sp. In Pacific Coast Nudibranchs, Behrens states it feeds on Halichondria and Haliclona species, but in Howe Sound and Agamemnon Channel, I have always found them on the Neoesperiopsis type of sponge. In fact, there seems to be a cycle of sponge abundance and depletion in the former location every two years. Until recently, I thought it was due to pollution. I'm starting to think it might be related to these nudibranchs.
