Biology
Oceanic species that probably approaches land to give birth (Ref. 13574, 58302). Epipelagic (Ref. 58302). Presumably feeds on schooling fishes and pelagic cephalopods (Ref. 247). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). With 2 pups in a litter (Ref. 247). Potentially dangerous because of its large size and big teeth (Ref. 13574). Utilized fresh, frozen, and dried or salted for human consumption (Ref. 247); meat (lower quality), fins (high value in adults), jaws (highly prized), skin and cartilage (Ref.58048).
