Nudibranch on Caulerpa taxifolia

Dear Bill,
To accompany my message on Elysia on Caulerpa taxifolia, here is a photo of another nudibranch found on C. taxifolia in Botany Bay (Sydney, Australia) at a depth of 3 m. Do you happen to recognise it?
All the best,
Tim Glasby

Dear Tim,
This is the aeolid Spurilla australis . It feeds on sea anemones. I have found it feeding on the little brown anemone Cricophorus nutrix. It is interesting because it is one of a group of nudibranchs which have evolved a symbiotic relationship with zooxanthellae [see Solar powered Sea Slugs Pages], but I'm afraid I can't think of any way it could help with the Caulerpa problem.
Best wishes,
Bill Rudman
