Ecology of Epinephelus itajara
 
Main Ref. Randall, J.E., 1967
Remarks Occurs in coral reefs, over shallow water. A solitary species (Ref. 26340) occurring in shallow, inshore areas. Found on rock, coral, or mud bottoms (Ref. 5217). Juveniles found in mangrove areas and brackish estuaries (Ref. 5217). Large adults may be found in estuaries (Ref. 5217). Adults appear to occupy limited home ranges with little inter-reef movement. Feeds primarily on crustaceans, particularly spiny lobsters as well as turtles and fishes, including stingrays. Territorial near its refuge cave or wreck where it may show a threat display with open mouth and quivering body. Larger individuals have been known to stalk and attempt to eat divers. Over-fished, primarily by spear fishing (Ref. 9710).
