簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 116 - 123; 臀棘: 2; 臀鰭軟條: 74 - 87; 脊椎骨: 125 - 129. Body very elongate and compressed. Head profile straight or scarcely convex, with sagittal crest strongly elevated. Both jaws have a short dermal process; the lower jaw longer than the upper jaw. The dorsal fin has a few weak anterior spines that hardly differ from the soft rays. Body color silvery, dorsal fin membrane black before the third to the fourth soft ray.
身體非常長與扁長形的。 頭部輪廓直線或幾乎不中凸, 與箭頭形的冠強烈升高。 雙顎有一個短的表皮突起; 下面的頜長度超過上頜。 背鰭有一些剛剛不同從軟鰭條的弱的前面棘。 體色銀色的, 第三個到前的背鰭薄膜黑色第四個軟的鰭條。
Probably benthopelagic from 150 to 400 m, juveniles epipelagic or mesopelagic. Feeds on fishes (including Engraulis mordax and Merluccius productus off California) and squids. Occasionally hooked, captured in nets, or found washed ashore. No special fishery.
可能來自 150 到 400 公尺的大洋底棲性魚種, 稚魚表層帶或中層帶。 吃魚 (包括 美洲鯷〔Engraulis mordax〕 與 Merluccius productus 加州外) 與烏賊。 偶然地鉤住,在網中捕獲, 或發現沖上岸。 沒有特別的漁場。
