Great white sharks are one of the most well-known and feared predators in the ocean.
These massive sharks can grow up to 20 feet long and weigh over 5,000 pounds. But where do these apex predators live?
Great white sharks are found in a variety of habitats around the world, from cool temperate waters to warm tropical seas.
They are most commonly found in coastal areas, where they hunt for prey such as seals, sea lions, and dolphins.
However, great whites have also been known to venture out into open ocean waters in search of food.

Habitat and Distribution
Great white sharks are found in almost all major oceans, from temperate to subtropical waters.
They are known to inhabit both coastal and offshore waters, as well as deep-sea habitats. Great white sharks are migratory, and their range can cover thousands of miles.
They are known to migrate to areas with high concentrations of prey, such as seals, sea lions, and other marine mammals.
Great white sharks are commonly found in the waters off the coast of California, particularly around the Farallon Islands and the Guadalupe Island.
They are also known to inhabit the waters off the coasts of Massachusetts, New York, and Florida.
Australia is home to a large population of great white sharks, particularly along the southern and western coasts.
They are known to inhabit the waters off the coast of South Australia, Western Australia, and New South Wales.
South Africa is another popular destination for great white shark sightings. They are known to inhabit the waters off the coast of Cape Town, particularly around Seal Island.
Great white sharks are also found in the waters off the coast of New Zealand, particularly around Stewart Island and the Chatham Islands.
While not as common as in other areas, great white sharks are known to inhabit the waters of the Mediterranean Sea, particularly around the coast of Spain.
Great white sharks are found in the waters off the coast of Japan, particularly around the Ogasawara Islands and the Izu Peninsula.
Mexico is another popular destination for great white shark sightings, particularly around the Guadalupe Island.
Great white sharks are known to inhabit the waters off the coast of Chile, particularly around the Juan Fernandez Islands.
Great white sharks are some of the most well-known and feared creatures in the ocean. They are apex predators, known for their size and strength.
This section will explore the physical characteristics of the great white shark, including their size and appearance, teeth and jaws, and biology and physiology.
Size and Appearance
Great white sharks are one of the largest predatory fish in the ocean. They can grow up to 20 feet long and weigh over 5,000 pounds.
Their bodies are torpedo-shaped and covered in a blue-gray or brownish-gray coloration, which helps them blend in with the ocean’s depths.
They have a distinct white underbelly, which is where they get their name.
One of the most recognizable features of the great white shark is its dorsal fin, which can be up to three feet tall.
This fin helps stabilize the shark as it swims through the water. Great white sharks also have five to seven gill slits on the sides of their heads, which they use to breathe.
Teeth and Jaws
Great white sharks have a powerful set of jaws filled with rows of serrated teeth. They can have up to 300 teeth at any given time, which they use to tear through their prey.
The teeth are constantly replaced throughout the shark’s lifetime, with new teeth growing in to replace old and worn teeth.
The jaws of a great white shark are incredibly strong, capable of exerting a bite force of over 18,000 newtons.
This allows them to bite through the tough skin and bones of their prey, including seals, sea lions, and other large fish.
Biology and Physiology
Great white sharks are cold-blooded, which means that their body temperature is regulated by the temperature of the water around them.
However, recent studies have shown that they may be able to regulate their body temperature to some extent, which would make them partially warm-blooded.
Great white sharks are part of the genus Carcharodon, which includes other species of sharks such as the extinct megalodon.
They are also known for their ability to swim at high speeds, with some estimates suggesting that they can reach speeds of up to 35 miles per hour.
Diet and Hunting Behavior
Great white sharks are apex predators and are known to feed on a variety of marine mammals, fish, and sea turtles.
Their preferred prey includes seals and sea lions, which make up a significant portion of their diet.
These large marine mammals are a vital source of food for the great white shark, and they are known to hunt them in areas where they congregate, such as rocky islands and offshore reefs.
In addition to seals and sea lions, great white sharks also feed on other marine mammals such as dolphins and whales.
They have been known to attack and feed on smaller species of sharks such as rays and other fish such as mackerel sharks.
Great white sharks are known for their stealth and speed when hunting their prey. They use a variety of hunting techniques, including ambush attacks from below and breaching the surface of the water to surprise their prey.
They are also known to stalk their prey from a distance, waiting for the perfect opportunity to strike.
When hunting seals and sea lions, great white sharks will often use their powerful jaws to grab their prey and shake it violently to incapacitate it.
They will then consume their prey whole, often swallowing it headfirst.
Great white sharks are opportunistic feeders and will often scavenge for food when prey is scarce.
They have been known to feed on the carcasses of dead whales and other marine mammals.
Reproduction and Lifespan
Great white sharks are known for their impressive size and power, but they also have fascinating reproductive and lifespan characteristics.
These sharks are slow to mature, with females not reaching sexual maturity until around 15 years of age and males at around 9 years of age.
During mating, male great white sharks will bite onto the female’s pectoral fin and use their claspers to transfer sperm.
Gestation lasts for approximately 12 months, and female great white sharks give birth to live pups. The litter size is typically between 2 and 10, with the average being around 5.
Great white sharks have a relatively long lifespan, with some estimates suggesting they can live up to 70 years in the wild.
However, determining the exact lifespan of these sharks is difficult due to their elusive nature and the challenges associated with studying them in the wild.
Researchers have used various methods to estimate the lifespan of great white sharks, including examining the growth rings on their vertebrae and analyzing the levels of carbon-14 in their tissues.
These methods have suggested that great white sharks can live for several decades, with some individuals reaching lengths of over 20 feet.
Conservation Status and Efforts
Great white sharks are listed as vulnerable by the International Union for Conservation of Nature (IUCN) due to their low reproductive rate and slow growth.
These factors make them particularly susceptible to overfishing and habitat loss. Great white sharks are also protected under CITES Appendix II, which regulates international trade in threatened species.
Conservation efforts for great white sharks include a variety of measures aimed at reducing fishing pressure and protecting critical habitat.
In South Africa, for example, great white sharks are protected within the country’s Exclusive Economic Zone, and the use of baited hooks and other forms of shark fishing is restricted.
In addition, a number of conservation organizations work to raise awareness about the importance of great white sharks and promote responsible shark tourism.
Despite these efforts, great white sharks continue to face significant threats, including accidental bycatch in commercial fishing operations, habitat degradation, and climate change.
To ensure the long-term survival of this iconic species, continued conservation efforts will be necessary.
Frequently Asked Questions
What is the largest great white shark ever recorded?
The largest great white shark ever recorded was a female measuring 20 feet (6.1 meters) long. The shark was caught off the coast of Canada in 1988 and weighed 5,000 pounds (2,268 kilograms). Source
How many great white sharks are estimated to be left in the world?
