Re: Colour variation in Gastropteron chacmol

The range of the color variation for Gastropteron chacmol noted by Ann and Marina in earlier messages is now extended to Cozumel, Mexico. This image is the first Cozumel specimen that I have seen that looks like the color variation previously reported from the Bahamas. The tiny nudibranchs are quite common on the sand flats above the reefs and easy to find once you know what to look for.

Locality: Colombia Reef, Cozumel. Quintano Roo, Mexico, Caribbean. Depth: 15 metres. Length: 3 mm. 15 August 2005. sand flat. Photographer: Jim Lyle

Dear Jim,
This is a nice contrast to your earlier photo [#13184] of an unspotted animal.
Best wishes,
