Short description

Dorsal spines (total): 0; Anal spines: 0. A large, spindle-shaped shark with large black eyes, a sharp snout, and large, narrow, hooked teeth with smooth edges (Ref. 5578). Caudal fin lunate, lower lobe strongly developed (Ref. 13574). Dark blue above, white below (Ref. 6581). Tiny second dorsal and anal fins (Ref. 26938).

Oceanic, but sometimes found close inshore (Ref. 6871, 11230, 58302). Usually in surface waters (Ref. 30573), down to about 150 m (Ref. 26938, 11230). Coastal, epipelagic at 1->500 m (Ref. 58302). Feeds on bony fishes, other sharks (Ref. 5578), cephalopods; larger individuals may feed on larger prey such as billfish and small cetaceans (Ref. 6871). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 43278, 50449). With up to 18 young in a litter (Ref. 26346). Tagging in New Zealand indicates seasonal migrations (Ref. 26346). Probably the fastest of all sharks and can leap out of the water when hooked (Ref. 6871). Potentially dangerous and responsible for unprovoked attacks on swimmers and boats (Ref. 13574). Utilized fresh, dried or salted, smoked and frozen; eaten broiled and baked (Ref. 9988). Valued for its fine quality meat as well as its fins and skin (Ref. 247). Oil is extracted for vitamins and fins for shark-fin soup (Ref. 13574). Jaws and teeth are also sold as ornaments and trophies (Ref. 9988). Give birth to 4-16 young, 60-70 cm long (Ref. 35388). 15-18 months gestation period; reproduces every 3 years. Diet consists primarily of small to very large fishes, as well as elasmobranchs, cephalopods and occasionally marine mammals (Ref.58048).
