Oceanic, pelagic and near bottom at 1->500 m (Ref. 58302). Depth range to at least 500 m (Ref. 247). Feeds on pelagic fishes (lancetfishes, herring, mackerel and small billfishes (Ref. 43278)) and bottom fishes (hake (Ref. 43278)) and squids (Ref. 247). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 43278, 50449). Stuns its prey with its long caudal fin (Ref. 247). Utilized for human consumption, liver oil for vitamins, skin for leather, and fins for shark-fin soup (Ref. 247).
