Hello everyone,
Is the red bay snook more closely related to caquetaia or parachromis?

My understanding is that is only SOME populations of "exCichlasoma" urophathalmus and based on cytochrome b .....mitochondrial DNA, so that would mean only SOME "exC." urophthalmus populations have more recent common ancerstory with Petenia splendida on the maternal side. Given "exC." urophthalmus's salinity tolerance and ability to move up the coast, and hurricane/flooding weather on the Atlantic over 1,000's of years, the chance of some hybirdization event in the past, would seem quite likely. some one correct me if i am wrong??Nuchal Man wrote:Bas is correct that Petenia splendida and 'Cichlasoma' urophthalmus are most closely related to each other according to a number of molecular phylogenetic studies.

So all that really means is that some populations of "exC." urophthalmus and Petinia splendida have common ancestory in the recent past. Consider that exC. urophthalmus has high salinity tolerance and can move up a coastline, and as well the frequency of hurricane and flooding over 1,000`s of years; maybe a hybirdization event might explain their closer relatioship.
