Ceratosoma brevicaudatum from Western Australia

January 30, 2007
From: Bruce Potter

Dear Bill,
Over the past couple of years I saw plenty of Ceratosoma brevicaudatum in Nelson Bay, New South Wales. They were usually quite large and pale in colour. I have now moved over to Western Australia and over the year end I dived under the Busselton jetty, where I saw lots of C. brevicaudatum but they were smaller and much more colourful than the ones I saw on the east coast.

Locality: Busselton, 8 metres, Western Australia, Indian Ocean, 6 January 2007, under a jetty. Length: 55 mm. Photographer: Bruce Potter.

This one was about 55 mm long.
Regards
Bruce Potter.

Dear Bruce,
For some reason, C. brevicaudatum in New South Wales is always quite pale, although there is quite a range in color. Certainly in South Australia and apparently right around the southern coast of Asutralia to southern Western Australia the colours become much more intense. I have no idea why.

Best wishes,
Bill Rudman
