সামুদ্রিক ব্যথিডিমারসাল সমুদ্র তলদেশবিহারী; গভীরতার পরিসীমা 50 - 1400 m (Ref. 247), usually 200 - ? m (Ref. 247). Deep-water; 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. Validity of this species is uncertain (Ref. 27638, not in Ref. 35766).
Length at first maturity / আকৃতি / ওজন / Age
Maturity: Lm 82.0, range 75 - 89 cm
Max length : 110 cm TL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 27000); সবের্াচ্চ প্রকাশিত ওজন : 7.3 kg (Ref. 40637)
পৃষ্ঠীয় কাঁটা (মোট ) : 2; পায়ূ কাঁটা : 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).
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Number of young usually only 1. Size at birth between 40 and 50 cm (Ref. 247). Distinct pairing with embrace (Ref. 205).
