Adults are found mostly on sandy bottoms near shore to 183 m depth. Juveniles are common beyond surf line, larvae settling in bays and estuaries (Ref. 122321). Adults feed during the day (Ref. 9643) on fishes and squids, often well off the bottom. An important sport and commercial fish. They are caught with trammel nets (Ref. 9330). Marketed as fresh fillet (Ref. 9330). Adults migrate to shallower waters to spawn (Ref. 9643). Has very sharp teeth and is known to bite if handled (Ref. 13513).
Distinct pairing (Ref. 205). They are batch spawners that exhibit indeterminate fecundiity and undergo asynchronous ovarian development (Ref. 122336). Spawning interval is between 7 and 14 days while spawning frequency is around 12 to 13 times per year.
