Max length : 110 cm TL 雄鱼/尚未辨别雌雄; (Ref. 247); common length : 75.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 247)
A slim, gray shark with tips of dorsal fins black and edges of pectoral, pelvic and caudal fins white; two dorsal fins each with strong, ungrooved spine at front edge (Ref. 26938).
Body shape (shape guide): elongated.
瘦, 灰色鲨鱼有背鳍顶端黑色与胸鳍，腹鳍与尾鳍白色的边缘; 二个背鳍每个具有强又无凹槽的棘在前缘.(参考文献 26938)
Inhabits continental shelves and uppermost slopes. Found in 60 to 380 m deep (Ref. 26938). Found on or near the bottom in large, dense schools. Probably feeds on bottom fishes and invertebrates. Ovoviviparous, with about 10 young per litter. A huge parasite (isopod) lives in its buccal cavity. Seldom used for food, but taken in commercial catches for its liver which yields oil and vitamins. Maximum depth reported taken from Ref. 55584.
栖息于大陆棚与最上面的斜坡。 发现于了 60 到 380 公尺深.(参考文献 26938) 栖息于近的底部较大时, 密集的鱼群。 可能吃底层鱼类与无脊椎动物。 卵胎生的, 有大约 10个幼鱼每胎。 一个大批的寄生虫 (等足目动物) 生活在它的喷水孔中。 很少用来当作食物, 但是对于产生油与维他命的它的肝脏采自了商业的捕获。 最大的深度报告取自参考文献 55584.
