Description

The red grouper is a sea bass of the family Serranidae from the western Atlantic Ocean. The species grows to about 1 m and has a robust, red-brown body that can pale and darken. Adults live mainly over rocky and muddy bottoms and are less common around coral reefs; they often rest on the bottom and are usually taken at depths of 70-330 m. Juveniles occur in shallow water. It excavates pits in the bottom and hunts fishes, crustaceans and cephalopods. Owing to overfishing the species is considered vulnerable. It is a sought-after food fish and harmless to humans.
