Biology:  Occur in bays and estuaries, but more commonly in deep offshore waters (Ref. 9563). Inhabit sandy substrates. Juveniles feed mainly on crustaceans such as copepods and mysidaceans, whereas larger fishes (11-20 cm) consume more polychaetes (Ref. 6223). Sexually mature below 13 cm SL and rarely exceeds 17 cm in Western Australia. Oviparous (Ref. 205), multiple spawner with asynchronous development (Ref. 12343). The flesh is soft and trawled fish are frequently bruised (Ref. 6205).
