簡単な記述 検索表 | 形態学 | 形態計測学
Snout long, narrow, sharply pointed. Dorsal scute row striating from just behind the head and extending to about behind a vertical through the anus, with more than 20 scute. Ventral scute row not reaching anus. Scute keels generally smooth blade-like, without multicuspid tips in small individuals (<30 cm), becoming more multicuspid with size. Scales adherent; belly completely scaled.
Primarily a pelagic feeder, feeds primarily on pelagic copepods, but also takes mysids, shrimps, cephalopods, fish, polychaetes and gastropods (Ref. 1371). Mainly reduced to fishmeal and oil (Ref. 1371).
