Littoral and epipelagic, in the open sea or near the bottom at 18-500 m (Ref. 58302). It is quick-moving and aggressive (Ref. 244). Solitary (Ref. 26340); often associated with schools of tuna (Ref. 244). Feeds mainly on fishes, but also squid, paper nautiluses, and pelagic crabs (Ref. 244; 37816). Viviparous (Ref. 50449). Regarded as dangerous to humans (Ref. 9997). Flesh utilized fresh and dried-salted for human consumption; its hide for leather; its fin for shark-fin soup; its liver for oil (Ref. 244). 2 to 14 young, 73 to 87 cm, are born per litter (Ref. 1602).
