Dear Jodi,
As you can see from the photos I have put at the Top of the Page, this species is either quite variable in colour or else there are a number of very closely related species which we have yet to sort out.

From anatomical studies this species is not a species of Chromodoris. It is usually considered a Hypselodoris but it has quite a few similarities to the genus Risbecia, so even its name isn't certain.

I'm afraid we don't know much about its biology either, other than it is a sponge feeder. I have photographed it feeding on an unidentified species of Dysidea, but that's about all I know about it. If anyone has more information and/or photos on any aspect of its biology, colour variation etc., I will be happy to add them to this page.

If you have any specific point you would like me to address Jodi, let me know and I will see what I can do.

Best wishes,
Bill Rudman.
