Diagnosis: large, predatory-looking species; very large mouth and big stout teeth; eye seems very small compared to scaled area of cheek beneath; upper surface of the tip of the premaxilla often extends almost horizontally for a considerable distance when viewed in profile (Ref. 55949).
Found in inshore reef and shelf zones, and offshore in the pelagic zone (Ref. 55949). Few specimens were collected near rocky shores. Occurs in small groups (Ref. 5595). Piscivorous (Ref. 5595, 55949). Female mouthbrooder (Ref. 55949).
