Phyllodesmium colemani ? from the Philippines

December 21, 2003
From: Erwin Koehler

Dear Bill,
Here are 2 shots of 3 Phyllodesmium from the Philippines, Cebu Island, divesite "airplane", which Ingo Burghardt [email] thinks to be Phyllodesmium colemani. Ingo is doing some research on 'solar powered sea slugs' and thought we should ask the person who described this animal to be sure. I collected two of them (as I thought) but in my room I realised there were three. So I took one shot in a dish - ventral view.
Length 28mm [ventral photo], 31 and 72mm, [upper photo]
depth 7m

Dear Erwin,
Sorry for the delay in answering this. If it makes you feel any better you are not the only one with messages which are taking a long time to answer. Even though I named this species, there are so few records of it that I can't admit to being an expert on its identity. Specimens from Lord Howe Island seem to have a rather different colour pattern, lacking the white blotches found in animals from the Philippines, but I suspect that reflects a natural variability rather than different species. The general shape, ceratal arrangement and preference ofr Tubipora musica all suggest it is P. colemani
Best wishes
Bill Rudman
