附註 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).
