dc.description.abstract Recent genetic evidence has highlighted the possibility of speciation with gene flow. In marine systems, dispersive larvae accompanied by the paucity of marine barriers, greatly decrease the chances for reproductive isolation. Even when a small number of cases of speciation with gene flow have been documented in coral reef fish, this mode could represent an important alternative for explaining the observed diversity in these systems. In this work we present a brief review of the main mechanisms of speciation that operate in the marine environment, examples of groups that are known to hybridize, as well as current genetic techniques for analyzing speciation with gene flow. We give a brief explanation of the molecular work we have done so far with grunts of the Haemulon genus, from the Tropical Eastern Pacific and Western Atlantic. In addition, we highlight the importance of scientific diving for collections in complex environments such as coral reefs, as well as its role in allowing observation of specific behaviors that help elucidate the speciation of fishes. en_US
