Eastern Atlantic: Gulf of Gascony, Madeira, Morocco, Mediterranean; also Cape Verde (Ref. 27000). Western Atlantic: Yucatan Shelf, Mexico (Ref. 9939), Brazil (Ref. 53443). Indo-West Pacific: off South Africa and Maldives, Madagascar, southern Japan, Australia, and New Zealand (Ref. 13568). Expected to occur in the Western Central Pacific (Ref. 13568).

Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - 360 cm
Max length : 450 cm TL male/unsexed; (Ref. 89422); max. published weight: 289.0 kg (Ref. 9939)
soft rays: 0. A shark with a short, pointed snout, small eyes, protruding spike-like teeth, and small, equal-sized dorsal and anal fins; first dorsal closer to pectoral than to pelvic fins (Ref. 5578). Grey above, paler below (Ref. 6586); may have red spots on sides (Ref. 5578).
Found on or near the bottom of the continental and insular shelves and upper slopes (Ref. 6871); sometimes in shallow water (Ref. 6871). Tagging showed the species dives up to 2,000 m at Malpelo Island, Colombia (S.Bessudo, pers.comm. 06/09). Feeds on small bony fishes, squids, and crustaceans (Ref. 13568). Uses its long body cavity and large, oily liver to regulate buoyancy. Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). Not implicated in attacks on people (Ref. 247). Flesh utilized for human consumption and liver for its high squalene content (Ref. 247); utilization of fins, jaws and cartilage (Ref.58048).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). Two young born at 105 cm or larger (Ref. 26346). Distinct pairing with embrace (Ref. 205).
