Description
The black grouper is a large grouper (Epinephelidae) from the western Atlantic Ocean. The species has a robust, olive-grey body with dark, rectangular blotches and grows to over a metre. It is a solitary inhabitant of rocky and coral reefs. As an ambush hunter it feeds mainly on fishes and crustaceans. It is a protogynous hermaphrodite and a valued food fish; owing to fishing pressure it is considered near threatened. Large specimens may carry ciguatera, but the living fish is harmless to humans.
