Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 52.7, range 60 - ? cm
Max length : 110 cm TL 雄鱼/尚未辨别雌雄; (Ref. 35388); 最大体重: 1.7 kg (Ref. 40637); 最大年龄: 54 年 (Ref. 41452)
背棘 (总数): 2; 臀棘 0. Head broad, rather soft; snout broad, rounded, with a large blunt tubercular scute at its tip; chin with small barbel. Scales relatively adherent; spinules dense on body scales, long, thin and recurved, narrowly lanceolate, with longitudinal anterior concavity. Pyloric caeca 29 to 31, long and slender. Color medium brown to grayish; orbits, oral and branchial cavities, and fins blackish to brownish gray.
头部宽的, 相当软; 吻宽的, 圆的, 在它的顶端具有一个大的钝有小瘤的鳞甲; 下巴有小的触须。 鳞片相当黏着的; 小刺密集的在身体鳞片上, 长的，细的与后弯的，狭窄矛尖形, 有纵向的前面凹洼。 幽门盲囊 29 到 31, 长且细的。 色彩普通褐色的到浅灰色的; 眼窝，口腔与鳃室与鳍黑色的到灰褐色。
Benthopelagic to bathypelagic in about 400 and 1200 m depth. Minimum depth from Ref. 1371. Form large schools at 600 to 900 m depth (Ref. 9988). Feed on a variety of fish and invertebrates, but primarily on pelagic crustaceans such as shrimps, amphipods and cumaceans; cephalopods and lantern fishes constitute a lesser portion of the diet. Batch spawner (Ref. 51846). This species is currently facing overexploitation in the North Atlantic. Utilized frozen and for fishmeal; can be fried and baked (Ref. 9988).
在大约 400 与 1200 公尺深中的底栖大洋性到底栖大洋性。 在 600 到 900 公尺深形成大群鱼群。 (参考文献 9988) 捕食多种鱼与无脊椎动物, 但是主要地在大洋性的甲壳动物例如虾，片脚类动物与 cumaceans 上; 头足类动物与灯笼鱼构成食性的较少的部分。 这种现在正在北大西洋中面对过渔。 冷冻使用了与用于鱼粉; 能被油炸而且烧烤。 (参考文献 9988)
