Chromodoris dianae from Malaysia

February 5, 2007
From: Mike Krampf

This one has me stumped as I haven't been able for find one that matches this color pattern. I'm guessing it's a Chromodoris sp but I haven't seen one before with the yellow spots and can't find it in my books or on the Forum. Can you help me ID this one?

Locality: Dive Site - Coral Garden off Mataking Besar Island, 60 Ft, Sabah, Malaysia, Celebes Sea, 03 February 2007, Fringing reef. Length: 3 cm. Photographer: Mike Krampf.

Thanks,

Dear Mike,

This is one of the colour forms of Chromodoris dianae. The other colour form has white gills with yellow tips. Interstingly we have a few records of that colour form feeding on a grey sponge Petrosaspongia [message #12000], and if you look at the lower left close-up you will see a similar sponge in the background which they may be eating. However just to make it difficult, there are another group of chromodorids with this black-lined pattern which feed on red sponges quite like the one being 'examined' by the bigger animal. So all I can say is that it is interesting to find these animals together near these sponges, but it may just be a coincidence.

Best wishes,
Bill Rudman
