生态学
海洋 深海底的; 非迁移的; 深度上下限 395 - 1700 m (Ref. 3587). 深水域; 55°N - 27°S, 26°W - 36°E
Eastern Atlantic: Irish slope to Cape Verde, including the Mediterranean. Occurrence in southern Africa is based only on specimens from off Namibia and not 'west coast of South Africa' as reported by Iwamoto 1986 (Ref. 2800 in FishBase) (Ref. 11953).
東大西洋: 到維德角的愛爾蘭的斜坡, 包括地中海。 在非洲南部的發生只以來自那米比亞外海的標本為基礎而不是 ' 南非的西岸' 當報告 Iwamoto 1986(參考文獻 2800 在 FishBase).(參考文獻 11953)

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.
Body shape (shape guide): elongated.
吻长的，狭窄的，和非常尖的。 背部的鳞甲列 striating 从在头部正后方而且在一个垂直的经过肛门后面延伸至大约, 藉由超过 20个鳞甲。 腹面鳞甲列不达到肛门。 鳞甲龙骨脊通常平滑的刀剑状的, 没有多犬齿顶端在小的个体 (<30 公分) 中, 用大小变成更多的多犬齿。 鳞片追随者; 腹面鳞片覆盖完整。
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).
主要地一个大洋性的捕食者,主要捕食大洋性的桡脚类的动物, 也捕食糠虾，虾，头足类动物，鱼，多毛类动物与腹足动物.(参考文献 1371) 主要地缩小成鱼浆或鱼油了。 (参考文献 1371)
