Biology     Glossary (e.g. epibenthic)

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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).
