What animal has the strongest bite. Who has the most powerful jaws? Shark bite pressure test

The jaw is probably the most common weapon in the animal kingdom. True, it is worth noting right away that the list is inaccurate due to the fact that there is no data on the bite of some animals.

For example, there is only theoretical data about the bite of a great white shark, and the most powerful bite in relation to its own size has Tasmanian devil, vaguely reminiscent of a wolverine in its habits and power.

In this list, you can get acquainted with the rating of the most powerful bites in the animal world.

10. Leo

Jaw strength - 41 atmospheres.

It may seem strange that this mighty predator and part-time King of beasts, occupies only the tenth position. The lion is the only social cat in the world. Lions prefer to hunt collectively, and perhaps for this reason, the jaws have not evolved as much as the jaws of some other cats. In addition, lions, attacking their victims, as a rule, suffocate them by simply biting their trachea, for which there is no special need for a strong bite.

Lions hunt both at night and during the day, although they hunt large prey mainly at night. They prefer to stay close to water, although they can live without it for up to five days.

9. Tiger

Jaw strength - 71 atmospheres.

Tigers are the most major representatives families of cats and, moreover, solitary hunters. In length, they can reach 3.5 meters, and weight up to 320 kilograms. The tiger goes hunting at night. Like lions, tigers prefer to choke their prey by the throat, cutting off the blood and air supply to the animal's brain. The bite of a tiger is much more powerful than a lion's bite, which may be due to the fact that they lead a solitary lifestyle. IN wild nature there are almost no tigers, the reason for which is excessive hunting. Tigers usually avoid humans, but attacks on humans have been recorded around the world.

8 Spotted Hyena

Jaw strength - 75 atmospheres.

Most sources say that the bite force of the spotted hyena is seventy-five atmospheres, but others indicate a much higher figure, which unfortunately cannot be verified. But one thing is for sure: the hyena has one of the most powerful bites in the animal world, and its jaws are so strong that they can even crush the bones of a giraffe. The probable reason that the hyena has formed such powerful jaws, lies in the fact that the hyena needs to somehow cope with the remnants of lion meals and what remains after other large predators.

Despite the fact that the hyena looks like a dog, in fact they are much closer to cats. In any case, hyenas are included in the cat-like suborder, like the cat family. Hyenas have been found to be capable of killing a dog with a single bite to the neck. It is a common misconception that hyenas steal prey from lions, but in fact, hyenas are much more successful hunters than lions and it is the lions who steal their prey for an hour. Just like lions, hyenas are very social animals and are excellent at cooperating with each other.

7 Grizzly Bear

Jaw strength - 81 atmospheres.

The grizzly bear is a North American subspecies of the brown bear and is distinguished large sizes and aggressiveness. True, biologists say that this is just fiction and that grizzlies are practically no different from those living in Eastern Siberia brown bears. Despite its considerable weight, the grizzly can reach speeds of up to fifty-six kilometers per hour. For the most part they feed on nuts, berries and other vegetation, but they can also hunt. IN national park Yellowstone grizzlies were caught on video while hunting.

Compared to other bears, grizzlies are considered more aggressive. It has been suggested that because of their huge size, grizzlies cannot climb trees. For this reason (also presumably) a powerful mechanism of aggression has developed in them, which allows not only to get their own food, but also to effectively resist any competitor. Presumably this one evolutionary path led to the fact that the grizzly formed such powerful jaws, with which he can cope with wolves and other intruders living in his possessions. Average weight the largest living in Alaska, the grizzly is about 450 kilograms. Contrary to the popular myth about super-dangerous killer bears, the grizzly bear does not consider a person as prey and will only attack in case of old age, illness, or being provoked to do so.

6 Gorilla

Jaw strength - 88 atmospheres.

It will seem strange to many that this herbivore is on the list of owners of the most powerful jaws. However, the gorilla is one of the rather formidable inhabitants of the jungle. With a height of about 170 cm, the weight of an adult male can reach 235 kilograms, despite the fact that these animals do not tend to accumulate excessive fat deposits and most of their weight falls on powerful muscles. IN scientific literature it was noted that individual male gorillas can reach a height of two meters and twenty centimeters!

The gorilla not only has very strong jaw but also powerful limbs. They almost never fight each other and limit themselves to demonstrating their power. They never attack other animals, but can defend themselves if necessary. Strong jaws evolved as an adaptation to eating hard plant food such as bamboo. The length of the fangs is 5 centimeters and, despite the overall colossal power, the muscles of the jaw and neck, which provide the gorillas with such powerful bite.

In the old days, gorillas were portrayed as huge monsters, but in Lately their image has become softer thanks to scientific research. After the chimpanzee, the gorilla is our closest relative. Unfortunately, these animals are on the verge of complete extermination, and there are only about seven hundred of them in the wild. They climb trees well, but prefer to live on the ground, huddle in groups of up to thirty individuals with a dominant male at the head. Completely safe for humans.

5. Hippo

Jaw strength - 124 atmospheres.

The hippopotamus is one of the most powerful herbivores. Although public attention has been drawn mainly to large predators like lions and leopards, as well as elephants and rhinos, perhaps it is the hippopotamus that is the most dangerous animal in Africa, which can only be surpassed by the black mamba or mosquitoes.

Hippos tend to defend their territory, and during mating season male hippos become extremely aggressive. It happens that a furious hippo will attack even small boats along with their passengers. Unfortunately, the scientists failed to measure the bite force of the male due to their excessive aggressiveness. As for the females, their bite force is given above. It is worth considering that females are not only less aggressive, but also inferior to males both in body weight (by about ten percent), and in size and sharpness of fangs.

The word "behemoth" itself comes from the Greek phrase "water horse", which was caused by incredible love this animal to the water. In the past, it was believed that the closest relatives of the hippopotamus are pigs, but more recent studies have shown that these are whales.

In addition, the hippopotamus is included in the order of artiodactyls, so goats and camels are also its relatives.

4. Jaguar

Jaw strength - 136 atmospheres.

The jaws of the jaguar are the most powerful among all members of the cat family. Moreover, we can safely say that its bite is superior in strength to the bite of any other mammal.

From Argentina to Mexico, the jaguar is the real king of the jungle. The jaguar kills its prey by biting its head. Like most cats, the jaguar is a solitary hunter. The jaguar even attacks the anaconda and caiman. The strength of his jaws is so great that he is able to bite through even a turtle shell. Although the jaguar is inferior in size to its cousins ​​living in Asia and Africa, they are the largest cats in America. The most numerous populations of jaguars, according to the latest data, live in Belize.

3. American alligator

Jaw strength - 145 atmospheres

American alligators are one of only two surviving alligator species (the other being the Chinese alligator). The American alligator has a population of about five million, with over 1.2 million living in Florida. Another part of the population lives in Alabama, Georgia, South and North Carolina, Louisiana and Texas.

American alligators share this territory with crocodiles. Their diet consists mostly of small mammals, turtles and fish. Recent studies, during which the bite force of this animal was measured, showed that this reptile occupies an honorable third place, and its bite force is 145 atmospheres. True, it is worth considering the fact that these data were obtained in the study of rather small alligators, therefore, in the case of more powerful individuals, the bite force can be noticeably higher.

2 Saltwater crocodile

Jaw strength - 251 atmospheres.

The saltwater crocodile was ranked first in the studies mentioned above for the strength of its bite, but again the bite strength of smaller specimens was measured. According to experts, if the strength of these small crocodiles is translated into the strength of a mighty six-meter giant, the strength of his bite can reach 480 atmospheres. These monsters live in Northern Australia, South-East Asia and East India.

Almost everything that he meets will be suitable as food for the saltwater crocodile. The inhabitants of Australia affectionately call these reptiles "salties", but in the event of a meeting with them, they, of course, would prefer not to meet such a salty. Saltwater crocodiles are responsible for most of the recorded attacks on humans, in any case, they are much more dangerous lion. True, it is worth noting that, like other animals, they do not consider a person as a prey and will not hunt him specifically. And since the habitats of these reptiles are designated as dangerous or completely prohibited for walking and swimming, a meeting with this giant does not threaten a cautious and law-abiding person.

1. Nile crocodile

Jaw strength - 340 atmospheres.

In the same experiment that measured the bite force of the saltwater crocodile and the American alligator, the Nile crocodile came in second, giving the palm to the saltwater crocodile. However, most sources claim that the force of his bite is three hundred and forty atmospheres! In size, the Nile crocodile practically does not differ from the saltwater crocodile.

Accordingly, it can be assumed that the strength of its bite is approximately in the same range as that of its marine counterpart. It should be noted that the Nile and saltwater crocodiles are interchangeable champions in terms of bite force, and their performance will vary quite markedly depending on how exactly the measurements were taken in the case of a particular crocodile. feed on Nile crocodiles mostly fish, but like their brethren they tend to attack any animal that is careless enough to cross their path. Mostly zebras, and even birds and small hippos.

A shark bite is dangerous because in most cases it is fatal. The shark rarely leaves prey bitten. An evolutionary arms race has provided the bull shark with a wide head and the most powerful bite force of any.

"It's all because of the width of the jaws that bulls have very huge heads," says marine biologist Philip Mott of the University of South Florida Tampa.

In a study by Maria Habegger, Mott and colleagues, scientists measured bite force in 13 species. "It's not that easy," they say.

In direct comparison, they got: a 2.7 meter bull shark has a bite force of 216 kg, a 2.4 meter great white 163 kg.

“A 5.4m big white will have a more powerful bite than a 3.3m bovine, simply because of the size,” says Mott.

A bull shark of the same size will have more strong bite

Evolution

How so? The buildup of evolutionary weapons is seen among juveniles. Research shows that having a stronger bite is necessary to gain an advantage over other species in being able to take on larger prey at a younger age. The growth of bite force is fast among juvenile fish, then it "evens out" in adults.

"They feed in murky coastal waters where they have to hold on to their prey," he says.

Some species, such as great whites, prefer to grab their prey and let it bleed out instead of holding it like bull sharks.

As it turns out, the image of a monster biting everything in its path is largely unfounded. Their bites are not as strong as we might imagine.

For years, information about the power of a shark's bite was largely mythical. Based on reports of bull, great white and tiger shark attacks, we know that many species produce enough force to dismember the human body. But no exact figures have been associated with these facts.

Shark bite pressure test

The first test to determine the pressure exerted by a shark bite was carried out in 1965 by two researchers who created a sensor consisting of a rigid aluminum tube wrapped in PVC with ball bearings inserted around the outside of the invention. [source: Martin].

The researchers wrapped the device in mackerel and gave it to the sharks to eat. Since different species have adapted to different kind food, the strength should be different.

Some species, such as the whale shark (the most large view) has thousands of teeth but does not use them. Instead, they have tissue that filters out plankton and small fish right in their stomachs.

Scientists have found that the black species (about 1.5 m long) has about 110 kg of force on the hind jaws.

This is not much, as a 1995 study found that the average bite force of 22 dog breeds was approximately 26 kg [source: Lindner]. But what about big guys like brindle, bull, big white? We talked about them above. It is indeed the teeth that cause the most damage.

If a person had the power to strike a praying mantis shrimp, he could launch a ball into space!

Most researchers have concluded that the number of deaths from great white shark attacks is disproportionately small compared to the number of attacks. Researchers at the University of New South Wales believe the species is dangerous because of its incredibly sharp and dense teeth, rather than the strength of its jaws [source: Live Science].

Teeth

Despite their destructive effect, shark teeth are easily lost. They don't have bones (supporting structures are made of cartilage), so their teeth don't attach to their jaws. While teeth can break off easily, they have the ability to re-grow them.

Thanks to the work of dog breeders, there are more than four hundred dog breeds today. Some representatives, such as the Pekingese, have seen the rise and fall of ancient empires, others have appeared more recently. A separate place is occupied by guard dogs, they are out of time and fashion, people love them as true friends and reliable guards.

When choosing a breed of dog that will play the role of a “security guard” or a house watchman, special attention is paid to speed, distrust, and the ability to make independent decisions. Not the last place is occupied by the moment, who has the strongest jaws. What dog breed has a powerful bite that can stop an intruder?

Not with teeth alone

Which dog bites the most? The one that really wants to bite. It looks like a joke, but only partly. The strongest jaws in dogs are not yet a guarantee that they will be used. There are breeds in which aggression is genetically absent - Labrador, Golden Retriever. Although they are not inferior to the German Shepherd in their strength and mass, these dogs are not capable of attacking a person.

Among representatives of guard breeds, it is rare, but still there are good-natured specimens that do a poor job of protecting the owner or property. In this case, the problem lies in education, under the guidance of an experienced dog handler in a Rottweiler, or perhaps awakening the inherent potential.

Anatomy of a bite

In fact, a dog is a construction of bones and muscles. Considering it purely from an engineering point of view, you can determine which dog breed has the strongest jaws. There is a clear correlation of physiological features.

For "biting" the pet must have a massive head with a large mouth. To maintain balance, such a muzzle should be attached to a short neck, which reduces the load on the spine. The optimal ratio is equal in size to the cranial and maxillary regions. In this case, the grip is quite deep and strong. In breeds with an elongated muzzle, for example, Russian Borzoi, with the strength of chewing muscles equal to the Doberman, this is why the bite will lose.

Bulldogs have short jaws great strength, but at the expense special structure they have a so-called "dead grip". Reduced grip and bite area. Breeds with a shortened nasopharynx have a weak sense of smell, and clinging to the enemy, they lose maneuverability and become vulnerable. It's hard for them to move quickly.

Golden mean

Knowing the aspects that affect the bite, one can understand that the strongest jaws in dogs of those breeds that have a fairly large head with a wide opening of the jaws. In addition, the guard must have a sufficient level of aggression and courage to use his formidable weapon. It was this rule that people were guided by, deducing protective guard breeds to protect a person and his property. In addition, guard dogs must have a calm disposition, be easy to train, and be devoted to the owner's family. An overly excitable dog does not respond well to commands and can turn from a protector into a troublemaker.

Dogs have the strongest jaws. Top rocks

There are breeds that are recognized as the best guards. They have the power of bite and the desire to protect the owner, his property successfully complement each other. Some of them appeared in the course of life, the main breeder was nature itself, living conditions did not allow puppies with insufficiently strong jaws and character to survive. Others were bred by man, but are not inferior in protective qualities and the ability to prove with their teeth to the enemy of the owner that he committed stupidity by encroaching on his property.

The strongest jaws in dogs of this breed are combined with large body sizes. The height of the male at the withers is 70 cm or more.

In addition, the blood of the herding and fighting breeds flows in the representatives of the CAO, which makes them vigilant, but balanced guards. Nature carried out selection in harsh conditions, and people polished the result. As a result, the dogs turned out to be ideal family members, kind to children and other animals, they are merciless to large predators and uninvited guests. On distant teeth, the bite force is at least 300 kg.

Cane Corso

Speaking about which dog has the strongest jaws, it is impossible not to mention this breed. True guards clearly divide the world into “us” and “them”.

They can safely be trusted with a child, a cana will lay down his life to protect the master's offspring. Defeating a dog consisting of 50 kg of iron muscles, possessing agility, fearlessness and incredibly sharp fangs is not an easy task. In the family circle, the animal is calm and good-natured.

Able to scare away with one look. Huge, lion-like dogs are able to make independent decisions and act according to the situation.

They must not be allowed to dominate, in which case the "Caucasians" are obedient and manageable. They do not have excessive aggression, but no one is allowed to offend the owner or encroach on his property. In terms of bite strength, it is not inferior to the two previous breeds - 13.5 atmospheres.

Rottweiler

More like a bodyguard than a watchman. He is focused on people, needs their society. Order is strictly observed in the controlled territory.

Sustained, calm, adequate, independent in decision-making. This breed needs a strict but friendly environment and thorough training. Great companion for adults and older children. The Rottweiler is friendly to kids, but may not distinguish between play with rudeness and react too violently. Compression force - 146 kg.

Excellent scent, lightning-fast reaction, sensitive ears and strong jaws - features breeds. It is worth adding here a remarkable mind, love for work and learning - and we get the perfect dog.

Sheepdog does not choose one owner, she perfectly obeys all family members. She must have a job - to guard the house, look after the children, accompany the owner. Without this, she misses, the character of the dog deteriorates. Force of pressure of teeth - from 120 to 315 kg.

Do not forget about pit bulls, bull terriers and American Staffordshire terriers. The strength of the jaws of these dogs is 120 kg or more. They have a strong grip, quick reaction, extremely maneuverable. Escaping them will not be easy. However, dogs of these breeds, with adequate education, are absolutely not hostile to humans and will not attack without a serious reason.

It is impossible to say unequivocally which breed has the strongest jaw in a dog. There are dozens of breeds in the world suitable for protection. And a representative of any of them in dangerous situation can set a record that no one will know about.

The main force of a human bite falls on the chewing teeth and muscles, it is extremely powerful and reaches a maximum pressure of over 113.4 kg. In general, the average human bite force in kg is 45-68. Some sources report that people do not use their full force when chewing food.

In fact, our teeth are strong enough and the force of a human bite is enough to chew on a cinder block. Amazing, right?

The bite of a person by a person is obvious, but in some cases the victim does not know
(for example, when the victim was drunk) or does not want to tell others who bit him (for example, due to a hand injury during a fight).

Be careful of cuts over the joints if they occur in combat, especially when the cuts are from another person's mouth being punched.

How dangerous is a human bite?

1. Let's start, of course, with the lions. These are incredibly beautiful and graceful cats are real killing machines. No one can feel at ease being near them. Lions attack even adult hippos. Nothing is impossible for them. At the same time, the bite force of a lion by African standards is very small - only about 40-50 atmospheres.

2. Cheetahs don't have the most strong bite, but incredibly sharp fangs and incisors leave no chance for the victim ...

3. Note: The cheetah's head is designed by nature to take up most of the respiratory system allowing you to run at great speed. There was no room left for large teeth.

4. Another cat that can kill an animal much larger than itself, and then drag the carcass up a tree - a leopard.

5. In terms of bite strength, the leopard is the most strong cat in Africa - according to various sources, from 100 to 125 atmospheres.

6. The hippopotamus has the most powerful jaws. And although it feeds mainly on grass, the hippopotamus needs a powerful jaw for battles with other hippos and for protection from predators. They are said to be able to bite into two parts of a huge crocodile. The bite force of these fat men reaches 125 atmospheres.

7. There are legends about the power of the jaws of a crocodile. And not in vain. These cutest creatures have a bite force of 340 atmospheres and this is the highest among all African animals.

9. Hyenas easily gnaw through strong bones and are even able to gnaw through steel bars of cages.

10. The strength of a hyena bite, according to various sources, ranges from 70 to 90 atmospheres, but incredibly strong and sharp teeth give power to the bite.
