She was tracked for 30 days after release. She was released because she would not eat and constantly bumped against the walls. [22][23] Similarities among the physical remains and the extreme size of both the great white and O. megalodon led many scientists to believe these sharks were closely related, and the name Carcharodon megalodon was applied to the latter. He was exhibited for 55 days, and was released into the wild on the 25th October the same year. [176][132] In Queensland, great white sharks that are found alive on the baited hooks are shot.
[163], The shark tourist industry has some financial leverage in conserving this animal. This shark is also known to prey upon a variety of other marine animals, including fish, and seabirds. They have bumped or knocked people overboard, usually biting the boat from the stern.

During feeding bouts of 15–20 seconds the sharks removed flesh with lateral headshakes, without the protective ocular rotation they employ when attacking live prey. [121] Another similar attack apparently occurred there in 2000, but its outcome is not clear.

They can go so fast that they completely leave the water. [18], Due to their need to travel long distances for seasonal migration and extremely demanding diet, it is not logistically feasible to keep great white sharks in captivity. A single set of great white jaws can fetch up to £20,000. For example, the government of Queensland has a "shark control" program (shark culling) which kills great white sharks (as well as other marine life) using shark nets and drum lines with baited hooks. [96] White shark predation on other species of small cetacean has also been observed.
Other operators draw the bait away from the cage, causing the shark to swim past the divers. For example, the dive industry in Gansbaai, South Africa consists of six boat operators with each boat guiding 30 people each day. Great white sharks live in almost all coastal and offshore waters which have water temperature between 12 and 24 °C (54 and 75 °F), with greater concentrations in the United States (Northeast and California), South Africa, Japan, Oceania, Chile, and the Mediterranean including Sea of Marmara and Bosphorus. In the 1980s, John McCosker, chair of aquatic biology at the California Academy of Sciences, noted that divers who dove solo and were bitten by great whites were generally at least partially consumed, while divers who followed the buddy system were generally rescued by their companion.

Recording it on video, he said that it weighed about 5,000 lb (2,300 kg), and measured 25–30 ft (7.6–9.1 m), evoking a comparison with the fictional shark Jaws. Ferreira describes the four encounters with the giant shark he participated in with great detail in his book "Great White Sharks On Their Best Behavior".[56]. Delivery is in spring and summer. [143], Great white sharks infrequently bite and sometimes even sink boats. [163] In South Australia, playing rock music recordings underwater, including the AC/DC album Back in Black has also been used experimentally to attract sharks.
[15] It is also protected by several national governments such as Australia (as of 2018). One of the densest-known populations is found around Dyer Island, South Africa. [114] The largest number of pups recorded for this species is 14 pups from a single mother measuring 4.5 m (15 ft) that was killed incidentally off Taiwan in 2019. [6] Adults of this species weigh 522–771 kg (1,151–1,700 lb) on average;[41] however, mature females can have an average mass of 680–1,110 kg (1,500–2,450 lb). [177], As of April 2007, great white sharks were fully protected within 370 km (230 mi) of New Zealand and additionally from fishing by New Zealand-flagged boats outside this range. [80], A 2007 study from the University of New South Wales in Sydney, Australia, used CT scans of a shark's skull and computer models to measure the shark's maximum bite force. [36] Great white sharks, like many other sharks, have rows of serrated teeth behind the main ones, ready to replace any that break off.

The original hypothesis for the great white's origins is that it shares a common ancestor with a prehistoric shark, such as the O. megalodon. [8] According to the same study, male great white sharks take 26 years to reach sexual maturity, while the females take 33 years to be ready to produce offspring. [82] In South Africa, white sharks have a dominance hierarchy depending on the size, sex and squatter's rights: Females dominate males, larger sharks dominate smaller sharks, and residents dominate newcomers. [26][27] One of the densest-known populations is found around Dyer Island, South Africa. Later, Sir Andrew Smith gave it Carcharodon as its generic name in 1833, and also in 1873.
Juvenile white sharks predominantly prey on fish, including other elasmobranchs, as their jaws are not strong enough to withstand the forces required to attack larger prey such as pinnipeds and cetaceans until they reach a length of 3 m (9.8 ft) or more, at which point their jaw cartilage mineralizes enough to withstand the impact of biting into larger prey species. [42][49] However, J. E. Randall believed that great white shark may have exceeded 6.1 m (20 ft) in length.
Prey is usually attacked at the surface. Great white sharks are ovoviviparous, which means eggs develop and hatch in the uterus and continue to develop until birth.
