Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

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).
