Ringless Chromodoris annulata?

March 28, 2003
From: Mary Jane Adams

Hi Bill,
I'm not sure what this is. It has some resemblance to other slugs from Thailand that you have called Chromodoris hintuanensis The gills, rhinophores and yellow spots look a lot like Chromodoris annulata. However, the two splotches of purple on the notum have me confounded. This slug was only 15mm long, so it could be a juvenile.

I photographed it at about 15 meters on an un-named divesite in the Mergui Archipelago, Andaman Sea, Myanmar. Feb. 17, 2003.

Best regards,
Mary Jane

Thanks Mary Jane,
I may be wrong but I am pretty sure this is a colour form of Chromodoris hintuanensis. Looking through the photos we now have on the Forum there seems to be quite a series showing a continuum in the colour pattern. Of great interest is the purple sponge your animal is on. It is probably the same as C. geometrica feeds on.
Best wishes,
Bill Rudman
