shark dive Fiji, Shark Reef, Tiger Shark Galeocerdo cuvier (Péron & Lesueur, 1822). The Tiger Shark can be recognised by its blunt head, serrated cocks-comb-shaped teeth and its colouration. Small juveniles are grey with dark reticulations, which change to vertical bars in fish up to 3 m in length. The bars may be faint or lacking in individuals longer than 3 m. The Tiger Shark grows to at least 6 m in length. It is a scavenger that will eat a wide range of prey and even indigestible objects. Its large size, scavenging nature and shallow-water feeding result in it being dangerous to people. The Tiger Shark occurs worldwide in tropical and some subtropical waters. Although sometimes seen well offshore, it is not an oceanic species.
