Bill,
Here is a photo of Mexichromis porterae mating which I took last Friday, July 16, 2004, while diving at Sutil Island, just off Santa Barbara Island, California.

Thanks Chris,
It's nice to get photos of this species which is so similar in colour to Chromodoris macfarlandi and Hypselodoris californiensis. We have a group of red-spotted chromodorids in southeastern Australia. All chromodorids have noxious glands in their skin and we think these groups of similarly coloured species have evolved because it is easier for fish predators to learn to avoid just one colour pattern.
Best wishes,
Bill Rudman
