Abstract
Acanthochromis polyacanthus is the only damselfish known not to disper se pelagic larvae. Moreover, it exhibits a color polymorphism among po pulations reported in taxonomic works (black and black/white in the pr esent study). Because of the limitation of gene flow due to benthic la rvae, the impact of such behavior on the genetic structure of the popu lation is of great interest. Genetic structure has been surveyed by en zymatic proteins and exhibited a narrow hybrid zone similar to the mod el of tension zone.
