They inhabit
continental shelf waters including estuaries, bays, inlets and also rivers. Juveniles form schools in shallow coastal bays and estuaries; adults move in large schools along shores, and can move over reefs in depths just sufficient to cover their bodies. They form large surface aggregations in deep water, feeding mainly on fishes but also onpelagic crustacean s, especiallykrill , "Nyctiphanes australis ". They also take food from the seabed.Adults are dark blue-green above and silvery below, with irregularly defined spots arranged laterally in indistinct rows. The lobes of the
caudal fin are long and powerful.They fight vigorously when hooked, and sometimes leap out of the water. When gorging on schools of
baitfish they will take any lure including a bare hook.References
