The great white shark is notable for its size, with larger female individuals growing to 6.1 m (20 ft) in length and 1,905 kg (4,200 lb) in weight at maturity.
However, most are smaller; males measure 3.4 to 4.0 m (11 to 13 ft), and females measure 4.6 to 4.9 m (15 to 16 ft) on average.
What is the largest great white shark on record?
Divers near the Hawaiian island of Oahu made a rare discovery over the weekend, capturing close-up photographs of what’s believed to be the largest great white shark ever recorded in history. The predator — nicknamed “Deep Blue” and estimated to be 50-years-old — weighs in at 2.5 tons.
What is the average size of a great white shark?
Female: 15 – 21 ft.
Male: 11 – 13 ft.
Where is the largest population of great white sharks?
South Africa is thought to be home to the largest population of Great White Sharks in the world, with False Bay, Gansbaai and Mossel Bay being the best places to see the Great White Sharks in South Africa.
Are female great white sharks bigger than males?
In large ocean fish species, females are almost always bigger than males, because they need more girth to carry their young, Fischer noted. (See great white shark pictures.) However, even a male of Apache’s size is not unheard of among great whites, other experts say.
Are there any great white sharks in captivity?
Since 1955, numerous attempts have been made by aquariums to place great white sharks into captivity. Marine biologists believe that because we are unable to create a suitable artificial environment for great whites in captivity causes them to become depressed. They aren’t at all happy with their new environment.
How long can a great white shark get?
Female: 4.5 – 6.4 m
Male: 3.5 – 4 m
Was the Megalodon the biggest fish?
Earth’s largest known shark, Carcharocles megalodon, ruled the seas for more than 20 million years. The megalodon, which went extinct millions of years ago, was the largest shark ever documented and one of the largest fish on record.
Do great white sharks swim in packs?
Great whites are considered social creatures that travel in a group called a school or a shoal. When one great white wants to take the other’s prey, both sharks will display various slapping demonstrations to discourage each other. They try to avoid fighting because just one bite may disable the shark permanently.
Which state has the most shark attacks?
Yearly Worldwide Shark Attack Summary

How old is Deep Blue?
A 2014 feature on Deep Blue created by Discovery said the shark is the largest great white ever filmed, measuring more than 20 feet and believed to be at least 50 years old. The Smithsonian says the average female great white shark measures between 15-16 feet, while males measure between 11-13 feet.
What to do if you’re attacked by a shark?
If attack is imminent, defend yourself with whatever weapons you can, advises the ReefQuest Centre for Shark Research. “Avoid using your [bare] hands or feet if you can avoid it; if not, concentrate your blows against the shark’s delicate eyes or gills.” A shark’s snout is also said to be sensitive.
Is it true that sharks never stop swimming?
Myth 1: Sharks Must Swim Constantly or They Die! Some sharks must swim constantly in order to keep oxygen-rich water flowing over their gills, but others are able to pass water through their respiratory system by a pumping motion of their pharynx. This allows them to rest on the sea floor and still breathe.
Why do sharks bite when they mate?
Based on observations of other shark species, researchers believe male white sharks must first bite their mates near their heads or pectoral fins, giving them enough leverage to insert their claspers. Impregnated females then migrate for two years, a behavior that’s likely linked to their 18-month gestation period.
Are female whales bigger than males?
Among mammals, male-to-male combat to establish dominance typically makes males larger—think massive elephant seals battling for territory. There are some exceptions, like female baleen whales, which are bigger than males. Humpback whale females can reach 60 feet while males are slightly shorter.
Can great white sharks be in aquariums?
Several aquariums around the world house whale sharks, the biggest fish in the sea, but not one has a great white shark on display. In 2004, it acquired a shark that became the first great white to survive in captivity for more than 16 days.
Are some sharks friendly?
In general, sharks do not eat humans. Despite their scary reputation, sharks rarely ever attack humans and would much rather feed on fish and marine mammals. Only about a dozen of the more than 300 species of sharks have been involved in attacks on humans.
How many great white sharks are there?
When experts reevaluated data from a 2011 study of great white shark populations off the coast of central California, they estimated that there are about 2,400 adult great white sharks in the area—and perhaps, says Burgess, “several times more than that.” Previous estimates put the number at just 219.
Are great whites endangered?
Why are great white sharks going extinct?
Threats. Great white sharks are decreasing in numbers and are rare due to years of being hunted by man for fins and teeth, and often as a trophy for sport fishing. The white shark is often caught as bycatch by commercial fisheries and can also become entangled in meshes that protect beaches.
How big can a megalodon get?
Megalodon could grow up to 60 feet (18 meters) long and had a bite more powerful than that of a Tyrannosaurus rex. The sea monsters terrorized the oceans from about 16 million to 2 million years ago.
Could Megalodon still live in the deep ocean?
‘No. It’s definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,’ notes Emma. ‘If an animal as big as megalodon still lived in the oceans we would know about it.’
Did Megalodon have any predators?
Predators and prey. In addition to being the world’s largest fish, megalodon may have been the largest marine predator that has ever lived. (Basilosaurids and pliosaurs may have been just as large.) Megalodon was an apex predator, or top carnivore, in the marine environments it inhabited (see also keystone species).
Did Megalodon exist?
Megalodon (Carcharocles megalodon), meaning “big tooth”, is an extinct species of shark that lived approximately 23 to 3.6 million years ago (mya), during the Early Miocene to the end of the Pliocene.
How far do great white sharks swim in a day?
The seals swim on the surface and the great white sharks launch their predatory attack from the deeper water below. They can reach speeds of up to 40 km/h (25 mph) and can at times launch themselves more than 3.0 m (10 ft) into the air.
Do sharks travel in schools?
Many sharks, including the whitetip reef shark are cooperative feeders and hunt in packs to herd and capture elusive prey. These social sharks are often migratory, traveling huge distances around ocean basins in large schools. These migrations may be partly necessary to find new food sources.
How many teeth do great white sharks have?
What do sharks hate?

Will great white sharks attack humans?
Out of more than 489 shark species, only three are responsible for a double-digit number of fatal, unprovoked attacks on humans: the great white, tiger, and bull. The oceanic whitetip has probably killed many more castaways, but these are not recorded in the statistics.
How many people are killed by coconuts?

Do killer whales eat humans?
Killer whales (or orcas) are powerful predators capable of killing humans, leopard seals and great white sharks. They have also been recorded preying on usually terrestrial species such as moose swimming between islands. In the wild, there have been no fatal attacks on humans and only one reported bite.
Are polar bears dangerous to humans?
Bear danger is the risk encountered by humans and their pets or livestock when interacting with bears. Although most bears are alpha predators in their own habitat, most do not, under normal circumstances, hunt and feed on humans.
