Ceratosoma amoenum from South Australia

April 12, 2010
From: Agnieszka Malkowska

Hello list,

My name is Aggie and I took a photo of this pair while diving on the wreck of Glenelg Dredge, South Australia, sometime in the past year. However I cannot find the common or scientific name of the nudibranch in any book I own.
Please assist with your vast knowledge in identifying these little guys.

Locality: Wreck of Glenelg Dredge, depth approx 20 meters, South Australia, Australia, [6 km west of Adelaide in St Vincent Gulf]. Length: Approx 2-3 cm. Photographer: Agnieszka Malkowska.

Thanks
Aggie Malkowska

Dear Agnieszka,

This a colour form of Ceratosoma amoenum apparently found only in southern Australia. While most species of Ceratasoma are found in tropical waters, this species is found in New Zealand, and southern Australia from New South Wales to Western Australia.

It is nice to get this photo because it shows the species on a species of Dysidea, which is one of the sponges it feeds on.

Best wishes,
Bill Rudman
