A coastal and freshwater shark inhabiting shallow waters especially in bays, estuaries, rivers, and lakes (Ref. 244). It readily penetrates far up rivers and hypersaline bays and littoral lagoons (Ref. 9997, 44894, 81283). Capable of covering great distances (up to 180 kilometers in 24 hours), moving between fresh and brackish water at random (Ref. 44894). Adults often found near estuaries and freshwater inflows to the sea; young enter rivers and may be found hundreds of km from the sea (Ref. 4967, 44894, 58304). Feeds on bony fishes, other sharks, rays, mantis shrimps, crabs, squid, sea snails, sea urchins, mammalian carrion, sea turtles, and occasionally garbage (Ref. 244, 5578, 44894). Viviparous (Ref. 50449). Gives birth to litters of up to 13 young (Ref. 26938, 44894). Size at birth is 56-81 cm TL (Ref. 81623). Sexual maturity is attained after 10-15 years (at a length between 160-200 centimeters) (Ref. 44894). Though not commercially important, this species is a good food fish (Ref. 12484). Utilized fresh, fresh-frozen or smoked for human consumption, fins for soup, hide for leather, liver for oil, and carcass for fishmeal (Ref. 244). Very hardy and lives well in captivity (Ref. 244). This large shark is potentially dangerous to man (Ref. 81283), probably the most dangerous species of tropical shark (Ref. 244), and it is repeatedly implicated in attacks on humans (Ref. 4967, 44894); attacks in fresh water are rare (Ref. 44894).
