Phyllidia varicosa from the Great Barrier Reef

G'day Bill,

I took this photograph at Challenger Bay on Ribbon Reef #10 on the Great Barrier Reef

I think it might be Phyllidia coelestis.

Locality: Challenger Bay, Ribbon Reef #10, Great Barrier Reef, 7.3 metres, Queensland, Australia, Pacific Ocean, 20 August 2006, Sandy with coral boulders. Length: ~ 3 cm. Photographer: Andrew Trevor-Jones

Thanks,
Andrew.

Dear Andrew,
It certainly seems to have quite a bit of black on the mantle, like some P. coelestis, but in that species there is a central black band with a ridge on each side of the midline. In your animal we have the opposite with a ridge in the midline, which would make it Phyllidia varicosa.

Best wishes,
Bill Rudman
