Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 2; Espinas anales: 0. Dorsal fins with very small spines, very short snout, lanceolate upper teeth and bladelike lower teeth with short, oblique cusps, stocky body that does not taper abruptly from pectoral region, very large lateral trunk denticles with smooth, circular, acuspidate crowns in adults and subadults (Ref. 247). Uniformly golden brown to dark brown in color (Ref. 6871).

Found on continental slopes and abyssal plains (Ref. 6871). Feeds mainly on fish (including sharks) and cephalopods (Ref. 6871), also gastropods and cetacean meat (Ref. 5578). Ovoviviparous (Ref. 205), with 13 to 29 young per litter, born at 27-31 cm (Ref. 26346); 32-35 cm TL in North Atlantic (Ref. 98315). Utilized as fishmeal, dried and salted for human consumption, or as a source of squalene (Ref. 6871).
