Data for: Angels in disguise: Sympatric hybridization in the marine angelfishes is widespread and occurs between deeply divergent lineages

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.
