Concerning message #19409:

Dear Bill,

These are some pictures from  Rio de Janeiro, Brazil, of color variation in intertidal specimens of Aplysia brasiliana.

As you can see, animals with and without red parapodial border occur together. A lot of specimens, with considerable variation, can be found this month in Rio de Janeiro.

Medina et al.(2005), based on DNA sequence analysis, suggested that A. brasiliana and A. fasciata are synonyms, and that A. cervina is very closely related, if not the same.

Dear Vinicius,
As I discussed earlier [#12545], your previous photos certainly indicated that A. brasiliana and A. fasciata were almost certainly the same species. I'm surprised I missed this paper but very glad that you have drawn my attention to it. I will have to find some way to merge the large lists of messages on the Forum for these two species.

Best wishes,
Bill Rudman
