Lateral line gradually curving down toward caudal peduncle. Intestine with 2 folds and 3 limbs. Swim bladder absent. Body covered with small scales. Sides with several poorly defined rows of round spots, larger than pupil but smaller than eye diameter. The inner surface of the pectoral fin is dark blue, the cheeks and belly silvery white, the anal fin and anal finlets light silvery gray, and the dorsal fin black, bright steely blue when fresh.
Found more commonly in offshore, open waters away from reefs and shoals (Ref. 30199). Form large schools which move close inshore along the coast of Queensland, commonly taken between December and April or May.
