Usually found in the upper layers of warm water above the thermocline, but also capable of descending to rather deep water. Often migrate into near-shore waters. Occasionally form schools or smaller groups of 3 to 30 individuals, but often occur in loose aggregations over a wide area. Feed mainly on small pelagic fishes but also takes bottom-dwelling organisms. Females grow larger (Ref. 4770). Utilized fresh, canned and frozen; eaten steamed (Ref. 9987).
Around Florida in USA, this species often moves inshore into shallow waters where females, swimming sluggishly with their dorsal fins extended and accompanied each by one or more males, may spawn near the surface in the warm season. However, spawning in offshore waters beyond the 100 fathom isobath was also reported from south of Cuba to Carolina, USA. Off southeast Florida, a 33.4 kg female may shed up to 4.8 million eggs in three batches during one spawning season.
