Phidiana bourailli from Heron Island

September 19, 2002
From: Julie Marshall

Dear Bill,
Attached are a couple of photos of Phidiana bourailli from Heron Island [Great Barrier Reef, Qld, Australia]. Like the photos of animals from the Marshall Islands that Scott sent you the main colour of the cerata is white although the base of each cerata is black. Both animals were 10 mm and were found in November 1999 and March 2001 respectively. I always find this species under dead coral slabs at the reef crest.

Best wishes,
Julie Marshall

Thanks Julie,
I have added a close-up to show the very characteristic ornamentation on the rhinophores.
Best wishes,
Bill Rudman
