The great white shark is the most incredible, terrifying, misunderstood creature in the ocean. Great white sharks are frequently portrayed as violent creatures who enjoy attacking humans because the 1975 Steven Spielberg film Jaws made them famous. With just 72 attacks worldwide over five years, they pose a much more significant threat to people than people do to them. This number is insignificant when we consider that 100,000 people per year pass away from snake bites.
1) Great White Sharks Are Huge Species
Great white sharks can weigh several tonnes and reach lengths of up to 20 feet.
Their torpedo-shaped bodies enable them to go through the water at high speed. Together with their conical facial structure and broad, tooth-ringed jaws, they aid their ability to ambush prey. They rush in rapidly and bite to deliver a lethal blow.
2) Their Most Significant Threat Is from Humans
For food, people hunt a variety of shark species. Great white shark teeth are hunted and sold as jewelry because of their fame and size. Like other sharks, great whites are caught and finned, which involves hacking off the dorsal, lateral, and tail fins of the caught shark. Usually, still alive, the shark is returned to the water where it drowns since it is unable to swim and settles to the bottom of the ocean.
The fins are simpler to transport and sell, and they are frequently worth more than the entire shark. Particularly in China and communities of the Chinese diaspora, they are sold for use in soup and traditional treatments. Great white sharks are also unintentionally trapped in commercial fishing nets, where they frequently perish, and shark fin prohibitions in the United States and other nations have come under fire for not having a significant enough impact to help save shark populations8.
Great white sharks are apex predators that eliminate sick and frail creatures from their habitats, indirectly maintaining a healthy and balanced fisheries population. One of the numerous reasons why ocean experts worldwide wish to see them protected is due to this.
3) Great White Sharks Are Vulnerable Creatures
The two main risks to the populations of great white sharks are overfishing and being trapped in fishing nets. Despite the lack of comprehensive global population statistics on great white sharks, scientists concur that this species’ population are declining. Great white sharks are still classified as vulnerable and not yet endangered by the IUCN despite the amount of data it has gathered on diverse regional populations.
4) They Can Leap from The Water Like a Whale
Since jumping out of the water necessitates a significant amount of energy, great white sharks only do so when attempting to get their preferred prey: seals. However, these enormous sharks are perfectly capable of leaping out of the water and into the air when they are on the hunt.
5) Their Scientific Name Is Relative to Teeth
The great white shark’s scientific name, Carcharadon Carcharias, has an intriguing breakdown: Greek terms for sharp teeth and point or kind of shark are how the great white shark earned its Australian name of “white pointer.”
They don’t chew their food despite having big teeth; instead, they use their teeth to kill and capture their prey before tearing it into pieces that are easier to swallow.
6) They Possess Specialized Muscles that Maintain Core Body Heat
Due to a unique adaption, great white sharks can survive in waters that are too cold for other predatory sharks. Their ability to store heat produced by their muscles while swimming is known as regional endothermy.7 Their circulatory system then transports this heat to colder portions of their body, resulting in great white sharks having a warmer body temperature than the water they swim in. Great white sharks are the largest fish with this feature, which distinguishes them from the majority of fish, which are cold-blooded.
7) The Potential of Smell in Great White Sharks
Although you may have heard that great whites can detect blood from a mile away, this is untrue. But even in 100 liters or nearly 26 gallons of water, they can find a single drop of blood. 5 They frequently discover other sharks, seals, dolphins, sea turtles, sea lions, sea birds, and other species higher up the food pyramid.
8) To Find Prey up Close, They Use Electric Sensors
The smell is excellent, the white sharks are pretty strong, and they also have a sensor that can detect electricity. Sharks have a system that detects the electrical fields of other creatures’ hearts. It is known as the Ampullae of Lorenzini.
It’s inside their noses, a tiny chamber packed with nerves that are enclosed in a tube filled with gel and have a pore that opens into the surrounding ocean. Great white sharks typically use this sense to locate their prey near them.
9) They Don’t Genuinely Have Black Eyes
Sharks’ vision in dim light is enhanced by a reflecting layer of glossy cells behind the retina. They can see practically everything because, unlike most other predators, their eyes are situated on either side of their heads. As if their noses, teeth, and bodies weren’t already well-suited for hunting, their eyes also have a blue rim hidden under the black exterior.
10) They Are Poisoned from Within
Other than great white sharks and orcas, great white sharks are not particularly threatened. The amount of arsenic and mercury found in great white sharks’ blood would be fatal to practically any other mammal in the world! However, if anything courageous enough to take a bite out of a shark in the wild would undoubtedly come to regret it.
11) the Risk of White Sharks Being Killed by Other Creatures Is Low
Great white sharks are currently listed as a vulnerable species on the IUCN Red List due to the overfishing and illegal hunting of these magnificent creatures. Great white sharks are unlikely to be eaten by other marine species because they are at the top of the food chain. Sadly, human activity poses a severe threat to them.
12) Approximately Everywhere, White Sharks Are Found
The world’s primary oceans have them, and Antarctica is the only continent where they do not reside and hunt. White shark populations are frequently concentrated in very productive temperate coastal seas, such as off the shores of Chile, northern Japan, southern Australia, northeastern and western United States, New Zealand, southern Africa, and the Mediterranean. Although some white sharks may venture into tropical or far-off waters on their own, field research reveals that most return to these peaceful feeding grounds every year.
13) There Is a Threat to The Great White Shark’s Extinction
They have been classified as vulnerable because their numbers have drastically decreased in recent years. This is a result of human activity, with overfishing and unintentional entanglement in fishing equipment being two of the main contributors.
Great white shark extinction, according to biologists, is mainly caused by overfishing, pollution, and habitat damage. Additionally, because great white sharks take a while to reach maturity, there are fewer fish that can reproduce, which slows down population growth. Although there are no accurate data available, scientists agree that the population of large white sharks is quickly dwindling. Their two main dangers are accidental entanglement in fishing nets and overfishing.
14) Sharks Predate Dinosaurs by A Large Margin
Sharks have existed in some form for more than 400 million years, a remarkable evolutionary feat. Shark fossils can be found as early as 450 million years ago, which indicates that these animals existed at least 90 million years before trees and 190 million years before dinosaurs. Great whites may have doomed the giant shark that has ever existed.
15) They are Impatient
White sharks are sophisticated, inquisitive apex predators with intricate behavioral patterns. Sharks are, in reality, curious about the things in the water and their surroundings. One researcher remembers observing great whites approach brightly colored objects on numerous occasions and frequently nibbling on them. Humans are at the top of the marine food chain despite being targeted by humans and lacking any natural predators. White sharks are consequently self-assured and intensely interested, especially the larger species.
16) White Sharks Have up To 300 Triangular, Serrated Teeth
These teeth are 3.81-6.35cm long and are arranged in 5 rows. They can develop up to 200,00 teeth in a lifetime and constantly lose and replace them. Probably some of the most feared marine animals are great white sharks. Given that their fangs can reach a maximum length of roughly two and a half inches, this dread is understandable. Serrations on the blade of great white teeth are rougher.
The great white shark’s teeth turn inward when the jaw is closed and outward when the mouth is open. The great white shark’s teeth have pressure receptors and sensory nerve cells, which give them a highly developed sense of touch.
17) Orcas Attack Them
Orcas, often known as killer whales, are frequently thought of as engaging in some type of competition with great white sharks. This results from an overlap in food choices because the prey that both marine animals seek is very similar.
However, the typical size of an orca is significantly larger than that of a great white shark, providing orcas with a significant size advantage. There have been several incidences that imply orcas are a great white shark’s predator.
Orcas are a source of fear for great white sharks, and for a good reason—killer whales will hunt and consume any sharks they come across. They would even extract a shark’s liver with almost surgical precision since they know that great white sharks rely on their livers for buoyancy. To consume the liver and heart of great white sharks, orcas chase them. Because the liver and heart are significant energy sources, orcas hunt great white sharks for their meat. Large sharks have been seen being caught, killed, and eaten by orcas.
18) Rarely Do They Sink Boats by Biting Into Them
With their razor-sharp teeth and powerful jaws, great white sharks have been known to sink rubber sailboats that are up to 10 meters (33 feet) long. People have been bumped or thrown overboard by them, and they typically bite the boat from the stern. A crew member was thrown into the water in one instance in 1936 when a giant shark ultimately charged the South African boat, Lucky Jim.
19) in The Womb, Shark Embryos Consume Their Siblings
In the womb, shark-fertilized eggs will consume their younger or weaker siblings. To continue growing, they also consume their moms’ unfertilized eggs. Thus, the sharks that survive after emerging from the womb are the strongest and most likely to persist.
20) White Shark Food
Large fish and seals are two of a great white shark’s favorite diets. Great whites that are fully matured primarily hunt animals like sea lions and earless seals.
Along with other aquatic animals like dolphins and huge crustaceans, great whites also hunt and consume a variety of fish species, including tuna, rays, and even other sharks. Smaller and younger great white sharks will stick to smaller fish species for food and avoid larger prey that is too difficult to hunt. Although great white sharks usually hunt alone, they occasionally congregate in packs to take down larger prey.
21) White Sharks Are Camouflaged
When viewed from above, their bodies’ tops merge with the rocky coastal sea floors. Because of their white bellies, they appear to be part of the sun when viewed from below.
22) They Can Hunt from Birth
Pups are the name for baby sharks that first develop inside eggs and then hatch while still in the womb. They are fully prepared for life when they are born, measuring 4-5 feet. They immediately swim away and begin to seek little aquatic creatures.
23) White Sharks Have Six Senses
Sharks have six senses, including
- hearing
- electroreception
- sight
- touch
- smell
- taste.
24) White Sharks Don’t Have Eyelids
To defend themselves from harm when attacking food, Great White sharks roll their eyeballs back into their heads rather than having eyelids, which is fascinating. When attacking prey, some sharks’ third eyelids provide helpful protection. The eyeballs roll back under the actual eyelids if there is no nictitating membrane, giving one the “white-eyed” appearance. Great male whites are prepared to breed when they measure about 3.8 metres in length.
25) They Use Their Tongues to Taste-Test
They use a form of cartilage known as basihyal to make their tongue. They taste-test food using this tongue to check if they enjoy it.
26) They Act Like Hands with Their Teeth
Sharks use the flexibility of their teeth within their jaws to understand what they are biting.
27) Feeding Pattern
White shark pups eat fish and other sharks as food. As they age, sea turtles, seals, sea lions, porpoises, dolphins, and small whales are among their prey. Prey is typically pursued via ambush, where the shark tries to rush the prey by surprise and deliver a swift, decisive, deadly bite. Often, this initial surge is so powerful that the hard-hit could knock the prey out of the water or if it misses the target, could launch the shark into the air. The phrase “bite and spit” or “bite and wait” refers to this attack in which the sharks retreat and wait for the prey to perish swiftly.
28) Amount of Food Consumed by White Sharks
Let’s look at how much food a great white shark needs daily now that we know the types of foods they consume. A great white shark typically consumes 1% to 3% of its body weight while feeding. This can amount to up to 50lbs of food per meal, depending on the shark’s size! However, great whites often only eat once or twice per week when hunting. This equates to more than 11 tonnes of food over a year! For comparison, the typical human consumes about half a tonne of food per year. Because of their size and power, great whites must consume these enormous meals to maintain their vast bodies.
29) Ways how White Sharks Hunt Their Prey
Given how much food they need, it is no surprise that great white sharks are skilled hunters. Great white sharks are the top predators, using their incredible power and speed to quickly grab and destroy their prey. Sharp teeth are one of a great white shark’s most potent weapons. Up to 300 triangular teeth, each serrated and highly sharp can be found in great white sharks. A bite with these teeth readily takes away sizable parts from the meat due to the shark’s huge, gaping mouth; as a result, the prey frequently dies from blood loss and has little chance of escaping.
But a great white shark’s teeth aren’t its only weapon; in addition to their enormous power, speed, and razor-sharp teeth, great whites also possess a keen sense of smell that allows them to locate a single drop of blood in the ocean from a distance of more than half a kilometer away. This compensates for their poor eyesight and enables them to monitor their long prey distances. Great whites have excellent hunting skills, making it simple to capture the prey required to satiate their enormous appetites. When a great white captures its food, it utilizes its strong jaws to break off significant portions of the animal before swallowing the remaining pieces intact.
Great white shark packs will take turns attacking their prey to overload it with frequent strikes when attempting to take down a larger target, such as a whale. The shark will swim in rapidly, bite its target, and then swim away before repeating the attack. This is known as a hit-and-run attack.
Great white sharks are highly effective hunters who can quickly dispatch most of their victims. And virtually nothing can stand (or swim!) against a bunch of great whites when they cooperate.
