White Shark, Carcharodon carcharias (Linnaeus, 1758)

ANIMAL SPECIES:White Shark, Carcharodon carcharias (Linnaeus, 1758)

The White Shark is one of the most famous (and feared) species of shark. It is one of the few shark species that is dangerous to humans.

Alternative Name/s

Great White Shark, White Death, White Pointer

Identification

The White Shark has a torpedo-shaped body, a pointed snout and large pectoral and first dorsal fins. It has a lunate tail, black eyes and large serrated teeth. It is grey or bronze above and white below.

Size range

White Sharks can grow to at least 6 m in length and weigh 3000 kg.

Distribution

White Sharks are found worldwide in temperate, coastal waters.

In Australia they have been recorded from southern Queensland to north-western Western Australia.

Habitat

Worldwide in temperate, coastal waters.

Behaviour and adaptations

Feeding and Diet

Juvenile White Sharks normally eat squid and fishes such as stingrays and other sharks. As the fish matures, its diet changes. Adults eat seals, sea lions, dolphins and dead whales, although some will continue to eat fishes such as snapper. White Sharks have also been known to eat elephant seals, sea otters, turtles and sea birds.

Life cycle

Females mature at 4.5 m to 5 m in length. It is believed that a White Shark of 5 m to 6 m in length is likely to be 15 to 25 years old. However, the technique of aging sharks by examining growth rings in their vertebrae, is yet to be confirmed as accurate for this species.

Conservation Status (IUCN): VULNERABLE (VU)
Conservation Status (Federal): Vulnerable

Economic/social impacts

Despite Australia's reputation as "the place to go to see White Sharks", they are uncommon. There are no reliable estimates of the number of White Sharks in Australian waters however, evidence suggests that their numbers are decreasing.

This species is now protected in all Australian states and territorial waters. The White Shark is also protected in many places around the world. South Africa was the first to protect this species in 1992, followed by Namibia, the Maldives, Florida and California and Australia. New Zealand gave the White Shark protected species status In 2007.

The White Shark is a powerful predator, which provokes fear in many people. However, this may not be entirely warranted. Scientists are only recently building up knowledge on the biology, movements and vulnerability of this species. A new research project funded by the Natural Heritage Trust, and under the leadership of J. Stevens and B. Bruce, of CSIRO Fisheries, is one such study.
