Great White Shark is the common name for Carcharodon carcharias, a large predatory Shark found mainly in cool-to-temperate coastal waters across much of the world. It is notable for its size, powerful bite, and role as a top regulator of prey populations in nearshore ecosystems. Adults commonly reach 3.4–4.9 m (11–16 ft), with exceptional individuals reported around 6 m (about 20 ft).
As an Apex predator, the Great White Shark influences the behavior and distribution of seals, sea lions, and large fish, shaping local ecology beyond simple predation. It is also one of the most studied sharks thanks to tagging programs that reveal long-distance migrations and repeated seasonal return to feeding hotspots.
The Great White Shark belongs to the family Mackerel sharks (Lamnidae), a group that also includes makos and porbeagles and is adapted for strong, efficient swimming. Its scientific name, Carcharodon carcharias, reflects its serrated “tooth” (odon) morphology and shark-like form.
Adult Great White Sharks typically weigh about 680–1,800 kg (1,500–4,000 lb), with large females often outweighing males. Total length is commonly 3.4–4.9 m (11–16 ft), and mature females in some regions can exceed 5 m (16.4 ft). Their robust, torpedo-shaped body supports sustained cruising and short, high-power bursts during attacks.
The classic coloration—dark gray to brown above and white below—provides countershading that helps conceal the shark from both prey and potential rivals. Great whites have several rows of large, triangular, serrated teeth; functional teeth are continuously replaced, and an individual can shed thousands over its lifetime. Their sensory toolkit includes acute smell, vibration detection via the lateral line, and electroreception that can detect weak muscle-generated fields in prey.
Performance-wise, tagged individuals have been recorded swimming at burst speeds around 40 km/h (about 25 mph) during predatory strikes. Great whites are also capable of deep dives; tracking studies have documented dives commonly in the hundreds of meters and, in some cases, approaching roughly 1,200 m (about 3,900 ft) during offshore movements.
Great White Sharks occur in temperate and some subtropical waters worldwide, with well-known concentrations near South Africa, southern Australia, New Zealand, the northeastern Pacific (California and Baja), the northwestern Atlantic, and parts of the Mediterranean. They often frequent coastal shelves, seal colonies near islands, and productive upwelling zones where prey is abundant.
Although often associated with nearshore hunting, the species also undertakes long migrations across ocean basins. Tagging has revealed individuals traveling thousands of kilometers between feeding and offshore areas, sometimes returning to the same seasonal sites in subsequent years. By moving between habitats, great whites help connect and influence different parts of the Marine food web.
Diet shifts with size and opportunity: juveniles commonly eat fish, rays, and smaller sharks, while larger individuals take marine mammals such as seals and sea lions, as well as large fish and carrion from whale carcasses. In some regions, pinnipeds can be a major energy source for large adults, especially during seasonal seal abundance.
Great whites often hunt with stealth and surprise, approaching from below and behind and striking rapidly. Breaching attacks—where the shark launches out of the water with prey—are most famously observed near seal colonies in South Africa and elsewhere, driven by high-speed upward ambushes. After a major bite, a shark may release and wait for prey to weaken, reducing injury risk from struggling animals.
Behaviorally, great whites are generally solitary but can aggregate where food is concentrated, showing dominance displays and spacing rules rather than stable social groups. They are crepuscular to diurnal in many coastal contexts, adjusting activity to prey movements, water temperature, and human disturbance. Interactions with humans are rare relative to the animal’s range, but bites do occur and are often investigated under the topic of Shark attack dynamics.
The Great White Shark is listed as Vulnerable on the IUCN Red List (2019), reflecting ongoing pressures and relatively slow life history. Individuals mature late (often around 10–15+ years depending on sex and region), produce few offspring compared with many fish, and can live roughly 30 years or more; estimates commonly cite about 30–40 years in the wild, with some individuals potentially older. In captivity, long-term survival has historically been difficult, and documented lifespans are generally far shorter than in the wild.
Major threats include bycatch in gillnets and longlines, targeted killing in some areas, and illegal or unregulated trade of jaws and teeth. Although the species is not typically the main focus of Shark finning compared with other sharks, fin and meat utilization can still occur where individuals are retained, and broader fishing pressure reduces prey and increases mortality risk. Collisions with fishing gear and entanglement also contribute to deaths that may not be fully recorded.
Global population size is uncertain because the species is wide-ranging and sparsely distributed, but the best-supported scientific view is that total numbers are far lower than for most large marine fish. Some regional estimates suggest only a few hundred adults in certain subpopulations (for example, widely cited figures around the northeastern Pacific), underscoring vulnerability to even modest additional mortality. Conservation approaches include legal protections in multiple countries, bycatch mitigation, protection of key aggregation sites, and continued satellite tagging to map critical habitats.
