Colour variation in Ceratosoma brevicaudatum

September 14, 2000
From: Stuart Hutchison

Dear Bill,
Here are some Ceratosoma brevicaudatum from around South Australia. They're common here and vary in colour from quite red to very light, as per your other pictures. They seem to reach lengths of about four inches usually, but I have seen one or two up to about six inches long. Depth's range from shallows at 2m to as deep as it gets here (around 30m) on wrecks/sandy bottom. Common but often beautiful.

Dear Bruce,
Thanks for the photos. The one at bottom right on the blue sponge may be an interesting food record. C. brevicaudatum does seem to most common in South Australia, although it can be found from New South Wales around to southwestern Australia.
Best wishes,
Bill Rudman.
