White Shark can be found in the coastal surface waters of all the major oceans. The white shark also known as the great white, white pointer, the great white shark, or white death. White shark has no known natural predators other than the killer whale. They can perform unique hunting action to attack prey. Here are some facts about white shark that really amazed you.
1. White Shark Performs Breaching For Hunting
White Shark charges from below the prey at up to 40kmph (25mph). This results in huge sharks breaking the surface of the water while grabbing the prey. It can fly up to 3 m (10 ft) above the water. It’s an awesome spectacle.
2.White Shark Does not Prefer Too Bony Human Being as Prey
Sometimes people think that white shark hunted human being, but actually it’s a test bite. Human beings are too bony for a shark. They prefer fat, protein rich prey such as seal.
3.Great Whites Exploit the Sun During Predatory Approaches
Recent research has shown that Great Whites exploit the sun during predatory approaches. They are positioning the sun directly behind the prey and using it to their advantage.
4.Spy Hopping an Interesting Fact about White Shark
Great shark performs an interesting action called spy hopping, a rare occurrence among sharks. The shark actually breaks the surface of the water and looks above the ocean for prey. Some researchers have suggested that spy hopping possibly has to do with smelling for prey. Because smell travels faster through air than water.
5.Carnivorous White Shark
Great White sharks are carnivorous. They are preying on nearly any fish in the ocean. They prefer fat rich animal. Juvenile (before 15 years of age) sharks often hunt and eat small fish. Older sharks hunts larger prey, such as elephant seals, sunfish and even whales. Many juvenile Great Whites have been discovered to have inedible materials in their stomachs, including beer cans, license plates and shoes.
6. The Great White’s Distribution is Widespread
The Great White’s distribution is widespread. They found in every ocean and sea across the world. They are most commonly found as far north as the Upper Atlantic and Pacific, just south of Arctic waters and as far south as the southern tip of Australia. Most sharks stay close to coastal shelves. They prefer to hunt just off the coastline.
7. Mysterious Reproduction
The exact reproduction process of the Great White is still very much shrouded in mystery. Sharks reach reproductive maturity at 15 years. Female hatch their eggs internally then give birth once their pups. They are strong enough and eat the weaker eggs while gestating. The sharks give birth between spring and summer and often have specific breeding grounds. These locations are is barely known to researchers.
8. Fact About Pups
Great Whites have anywhere between 1-5 pups. They have been theorized to take a year off between births. Pups are about 1 ft long when they are born and weigh around 5 kg. Their jaws tend to grow strong enough to kill within their first month of life and only get stronger thereafter.
9. White Shark the Fourth Largest Shark of The Earth
The whale shark is the largest of all shark. Basking shark and Mega mouth shark are also the second and third largest. White shark considered the fourth largest shark of the world.
10. Counter Shading of Body
Their light grey upper body and all white lower half is known as ‘counter shading’. From above, the Great White resembles the murky depths below, and from below, it resembles the light from the surface.
11. White Shark have Triangular, Serrated Teeth
Sharks attack their prey with their knife shaped teeth. They have approximately 35,000 teeth in a lifetime. The number around 3,000 in total, with multiple rows ready to replace those that are broken or fall out.
12. The Ampullae of Lorenzini- Shark’s Special Sensing Organ
Great white sharks, like all other sharks, have an extra sense. The ampullae of Lorenzinigives that. It enables them to detect the electromagnetic field emitted by the movement of living animals. Great whites are so sensitive they can detect variations of half a billionth of a volt. At close range, this allows the shark to locate even immobile animals by detecting their heartbeat.
13. Unbelievable Bite Force
In 2008, a team of scientists led by Stephen Wroe conducted an experiment to determine the great white shark’ jaw power. They find that a specimen massing 3,324 kg (7,328 lb) could exert a bite force of 18,216 newtons (4,095 lbf).
14. Attacks on Boats
Great white sharks bite and sometimes even sink boats. Only five of the 108 authenticated unprovoked shark bite incidents reported from the Pacific Coast during the 20th century involved kayakers. A few cases they have bitten boats up to 10 meters (33 ft) in length. They have bumped or knocked people overboard.
15. Great white sharks in captivity
Prior to August 1981, no great white shark in captivity lived longer than 11 days. In August 1981, a white shark survived for 16 days at Sea World San Diego before being released. Monterey Bay Aquarium housed a third great white, a juvenile male, for 162 days between 27 August 2007, and 5 February 2008.One of the largest adult great whites ever exhibited was at Japan’s Okinawa Churaumi Aquarium in 2016, where a 3.5 meters (11 ft) male was exhibited for three days before dying.
16. Cage Diving
Cage diving is most common at sites where great whites are frequent including the coast of South Africa, the Neptune Islands in South Australia. The popularity of cage diving and swimming with sharks is at the focus of a booming tourist industry. These practices may make sharks more accustomed to people in their environment and to associate human activity with food.
17. White shark Attack More on Human
Of all shark species, the great white shark is responsible for by far the largest number of recorded shark bite incidents on humans, with 272 documented unprovoked bite incidents on humans as of 2012.
18. White Shark can regulate its own body temperature
In contrast to most fish, which tend to be cold-blooded, the great white shark is warm-blooded. It can regulate its own body temperature. That allows it to adapt to different water temperatures.
19. Quick Swimmer
These sharks are very quick swimmers. They can swim at speeds of up to 15 mph (24 km/h).
20. Great white sharks can detect one drop of blood in 25 gallons (100 liters) of water
Great white sharks can detect one drop of blood in 25 gallons (100 liters) of water. They can sense even a little blood up to 3 miles (5 km) away. They use their acute sense of smell to detect blood using an organ called the olfactory bulb.
21. The Great White are Vulnerable
The great white shark is listed as vulnerable by the IUCN Red List. But it is going to be labeled endangered due to over fishing very soon.
