Chan, L., 2001 (Jul 17) Phestilla melanobrachia from Hong Kong. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/4768Dear Leslie,
This is Phestilla melanobrachia. It feeds exclusively on the corals Dendrophyllia and Tubastrea, usually preferring detached pieces of living coral. It has two colour forms, one bright orange, the other black, matching the two colour forms of the coral on which it feeds. In your photo most of the coral tissue has been removed from the skeleton. At top right, the small white dots are its eggs, which are deposited in dorid-like egg ribbons.
Best wishes,
Bill Rudman
