Short description

Dorsal spines (total): 2; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A large gulper shark with a short, broad snout, a long, low 1st dorsal fin, short pectoral rear tips, and large, rough, leaf-like denticles (Ref. 5578). Dark grey or chocolate brown in color (Ref. 5578).

Found on or near the bottom of continental slopes; also found pelagically in the upper 1,250 m of water 4,000 m deep (Ref. 31367). Presumably feeds on fish and cephalopods (Ref. 6871). Ovoviviparous (Ref. 50449). Utilized and fishmeal and dried salted for human consumption (Ref. 247); meat and fins (low value) and liver oil (very high value), and occasionally for its mature eggs (Ref.58048).
