North-western Atlantic, north-eastern and south-eastern Atlantic. Western and eastern Indian Ocean. South-western Pacific, north-western Pacific, and south-eastern Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm 124.5, 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).

Estimates based on models
Preferred temperature (Ref. 115969
): 4.1 - 10.6, mean 7 °C (based on 498 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00155 - 0.00426), b=3.20 (3.05 - 3.35), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.5 ±0.3 se; based on diet studies.
Generation time: 27.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
