簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 47 - 51. Head rather long. Pectoral fin tips usually reaching origin of anal fin. Caudal fin usually truncate, progressively becoming concave with growth. Color is steel gray to blackish on back, silvery white on sides and belly.
頭部相當長的。 胸鰭頂端通常達到臀鰭起點。 尾鰭通常截形的, 漸進地變成凹隨著成長。 色彩是鐵灰色的到黑色的背面, 銀白色在側邊與腹面上。
Feeds mainly on small fishes, and to a lesser extent on crustaceans and cephalopods. Undergoes seasonal latitudinal migrations (Ref. 9709). Spawning takes place in northern areas from January to March (Doutre, 1960), and from October to March (López Abellán and Ariz Telleía, 1993). Marketed fresh or frozen (Ref. 58452). Minimum depth reported from Ref. 26999.
