Description

The star-studded grouper is a large grouper of the family Serranidae from the eastern Pacific. The species has a robust, dark body studded with numerous small white spots, like stars, to which the name refers. It lives on rocky reefs and soft bottoms, sometimes at considerable depth; in the central Gulf of California it is often taken as bycatch in shrimp nets. As an ambush hunter it catches fishes and crustaceans. The species is too rare to be of commercial fishing interest and is harmless to humans.
