Adults live in large schools in waters overlying the continental shelf and slope except during the spawning season when they are found several hundred miles seaward (Ref. 1371). A nocturnal feeder (Ref. 6885) that feed on a variety of fishes and invertebrates (Ref. 1371). Important prey for sea lions and small cetaceans (Ref. 2850); also prey of dogfish (Ref. 11384).
