生態學
海洋 深海底的; 深度上下限 50 - 1400 m (Ref. 247), usually 200 - ? m (Ref. 247). ; 43°N - 43°S
Western Central Atlantic: Gulf of Mexico. Eastern Atlantic: western Mediterranean and Gibraltar to Senegal, Côte d'Ivoire to Nigeria, Cameroon to Angola, northern Namibia. Indian Ocean: southern Mozambique, uncertain records from India; Western Australia (Ref. 6871). Western Pacific: Australia (Ref. 6871); occurrence in Taiwan needs validation.

Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 82.0, range 75 - 89 cm
Max length : 110 cm TL 雄魚/尚未辨別雌雄; (Ref. 27000); 最大體重: 7.3 kg (Ref. 40637)
背棘 (總數): 2; 背的軟條 (總數): 0; 臀棘 0; 臀鰭軟條: 0. A small, slender gulper shark with a long, narrow snout, a short 1st dorsal fin and a high 2nd dorsal fin; pectoral rear tips usually very long; denticles small and flat (Ref. 5578). Brownish-grey above, light grey below (Ref. 5578).
A common deepwater dogfish of the outer continental shelves and upper slopes, on or near the bottom. Adults feed on bony fishes and squid. Males mature by 80 cm TL (Ref. 94782). Ovoviviparous (Ref. 50449). Utilized dried salted for human consumption and probably for fishmeal and liver oil (Ref. 247).
