Chromodoris geometrica feeding

March 28, 2003
From: Mary Jane Adams

Hi Bill,
I photographed this Chromodoris geometrica feeding on a black sponge on a vertical wall at Black Rock, Mergui Archipelago, Myanmar on Feb. 15, 2003. Length: about 25mm, Depth: 5 meters. I wish I could be more helpful, but is impossible to photograph any detail on an all black subject. I think the only way to ID this sponge would be in a lab.

Best regards,
Mary Jane

Thanks Mary Jane,
I assume its the same sponge as as Scott Johnson's series of photos from the Marshall Ids, and probably your recent photo of C. hintuanensis. From experience, these sponges are difficult to collect as they form such a thin layer over the rock or dead coral skeleton. Sponge experts need a whole thickness of the colony so often the only way is to collect the rock as well. Then there is the problem that often there may be two or more different species of sponge growing close together - or sometimes intertwined. After preserving the sponges in alcohol they lose their colour and so the obvious way of distinguishing the interwined colonies is gone. So you can't tell the expert 'I'm interested in the yellow bit' because its all now decolourised. Any way getting lots of photos establishes a pattern, so that when we get the chance to get a good specimen of the sponge, and get it identified, we can hopefully fill in a lot of gaps at once.
Best wishes,
Bill Rudman
