Length at first maturity / Size / Weight / Age
Maturity: Lm 126.1, range 110 - 158 cm
Max length : 164 cm TL male/unsexed; (Ref. 58048)
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).
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Young numbers 5-8 in a litter (Ref. 6871). Size at birth 35-43 cm (Ref. 26346). Distinct pairing with embrace (Ref. 205).
