Chromodoris cf africana & C. cf. strigata from Exmouth

April 4, 2008
From: Bruce Potter

Dear Bill,

Here is another of the blue black and orange Chromodorids from the Exmouth Navy Pier.

Locality: Exmouth, 10 - 12 metres, Western Australia, Indian Ocean, 5 October 2007, under a jetty. Length: 35mm. Photographer: Bruce Potter.

I think this might be Chromodoris africana but I am not at all convinced I have it right. [see also messages #20980, #20982,#20983,#20984 ].

Dear Bruce,
I think you have two different species here. The large animal is what I am calling Chromodoris cf. africana and I am pretty sure the small animal is Chromodoris cf. strigata. Unfortunately that means you haven't a 'real' name for either of them, but it is a useful bit of information to help sort them out.

Of particular interest is that both these animals seem to be feeding - or showing great interest - in the bluish-grey sponge they have their heads on, which I am pretty sure is a dysideid. Interestingly this is an unusual choice for a species of Chromodoris but we already have a record C. cf. strigata  [message #18512] feeding on a similar dysideid. 

Best wishes,
Bill Rudman
