Habitat degradation (development, pollution and overfishing) also threatens this species and may largely exclude it from areas, perhaps traditionally utilised for feeding or as nurseries, where it was historically much more abundant.Great White Sharks have been sought as the ultimate species to display in large public oceanaria, but with poor survivorship so far.Great White Sharks also occur, albeit less frequently, at many sites elsewhere (e.g., Brazil, Caribbean, Azores, Hawaii, north-west Africa, east Africa (Kenya, Tanzania), Seychelles, Mauritius, Madagascar, Sri Lanka, northern Australia, New Caledonia and Philippines). Parturition apparently occurs during the spring to late summer in warm-temperate neritic waters.
The majority of females mature at between 450-500 cm total length (TL) (Francis 1996), but have been reported as immature at sizes as much as 472-490 cm long (Springer 1939, Compagno 2001). A broad range of elasmobranchs - sharks and batoids - are eaten by Great White Sharks, as are chimaeroids, chelonians, cephalopods and other molluscs, crustaceans and occasionally sea birds such as cormorants and penguins (Compagno 2001).
Great White Sharks are curious and readily approach boats, scavenge from fishermens' nets or longlines and devour hooked fish taken by rod-and-line or swordfish harpoon.
This vulnerable propensity often results in either their own accidental entrapment or deliberate killing by commercial fishermen.
Directed fishery exploitation of Great White Sharks is primarily undertaken with the aim of trading its teeth and jaws as trophies or curios and its fins for the oriental fin trade.
In South Africa offers of US,000-,000 have been made for great white shark jaws and US0-0 for individual teeth.
