Concerning message #19152:
Dear Bill,
Concerning this message I agree with you about Mexichromis kempfi. Armando's photos from São Paulo and my photos here from Rio de Janeiro match more with the original description of this species, from the northeast of Brazil. There is a color variation in specimens observed here in Rio, but the specimens from the Caribbean region looks so much different and I'm not sure that they belong to the same species.
I don't believe that the bright pink egg ribbon in "Caribbean Sea Slugs" belongs to the slug alongside. I'm sending a picture of an egg ribbon of M. kempfi that were laid in the laboratory, with large, yellow eggs.
I'm looking for specimens from the Caribbean Sea to make anatomical studies and compare to the Brazilian material.
Regards,
Vinicius Padula

The large eggs suggest that this species has direct developing larvae, lacking a planktonic stage. If so, this could perhaps explain the consistent colour difference between Brazilian animals and Caribbean ones.
Best wishes,
Bill Rudman
