Hybridization is not uncommon in marine environments where physical barriers are attenuated. Research conducted on hybridization in coral reefs has grown rapidly, but the majority of studies have focused on parapatric species along biogeographical suture zones. Comparatively little attention has been directed towards sympatric hybridization on coral reefs, despite the large amount of biogeographical overlap that occurs among coral reef species. Here we investigate if the propensity for hybridization along suture zones represents a general phenomenon among coral reef fishes, by focusing on the marine angelfishes (Pomacanthidae). Although hybridization has been reported for this family, it has not been thoroughly surveyed, with more recent hybridization studies focusing instead on closely related species from a population genetics perspective. Here we provide a comprehensive survey of hybridization among the angelfishes, characterize the upper limits of genetic divergences between hybridizing species, and investigate the occurrence of sympatric hybridization within this group. Our results indicate that the marine angelfishes are among the groups of coral reef fishes with the highest incidences of hybridization, not only between sympatric species, but also between deeply divergent, sympatric lineages.
