The strongest bites in the world! The strongest jaws of the animal world Which crocodile has the strongest bite

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 most strong 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 sizes body. 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.

Everyone knows what cats are. When we hear this word, a picture of a domestic cat merrily frolicking with a ball is drawn in our head. But they are different: the largest are tigers weighing 350 kilograms, and the smallest “rusty” cats reach a weight of only 1.5 kilograms. Today we will look at the 10 scariest facts about wild and domestic cats.
So let's get started!
1. You can't run away from them! As you know, the most common domestic cat can reach speeds of up to 13.5 m / s while running,

By comparison, the fastest sprinter can run at a maximum speed of 12.5 m/s. I suppose there are few among us who can boast that he is an Olympic champion in running? But any "murka" living next door to you may well.

2 Have you already climbed higher, where the feline will not reach you? You can get off!

African leopards and cougars can make the highest jump. They are able to jump onto a tree branch (or rock ledge) located at a height of 5.5 meters. In general, cats jump up to five times their height.

3 Well, goosebumps ran down your back? Ah, you have no time, a Bengal tiger is chasing you?

Then it will be useful for you to know that this type of cat has the longest fangs (about 10 cm)! Running, as mentioned earlier, is useless, look for tall tree, perhaps the tiger will be too lazy to get you out of there.

4 Another great fact about bites. Do you know who has the strongest jaws? Look around.

Yes, yes, this cute tiger that follows you around. The force of his bite is 1000 pounds per inch (that's about 450 kilograms). It's impossible to get out of his grip. For those who stay at home, and the tiger does not threaten them, I note that the domestic cat has thin and long fangs. When bitten, it can harm not only soft tissues (muscles, ligaments), but also joints (just bite through it).

A cat's hearing is 20 times more acute than a human's. They can hear sounds that we bipeds can't.

6 The length of the claws itself major representative the cat family reaches 10 cm.

So don't let the softness and fluffiness of their paws fool you.

7 If a cat decides to hunt, then its victim will know about it at the very last moment.

All representatives of this species, except for the cheetah, use the surprise factor during the hunt. They sneak up on the victim as close as possible and attack unexpectedly. The innate noiselessness of their gait allows them to sneak up on them. Thanks to soft pads and wool on the paws, all possible sounds from their steps are muffled.

8 This type of mammal reproduces at an amazing rate, especially the subspecies of domestic fluffies.

One cat is capable of giving birth and raising more than 100 kittens in one life. Reference: on average, cats live 10-15 years.

9 Do not try to hide from a cat in a dark room or sneak up on a predator during a night safari!

They have a vision of 200 degrees, a person has only 180. Yes, and rods in the retina, which are responsible for the ability to see in the dark, they have more than 20 times more.

10 I Hope The Previous 9 Facts Already Scared You And Dreams Of Becoming An Animal Animal large predators or the second Kuklachev left you.

I'll get it last. Cats are always watching you! Even during sleep, one half of their brain is constantly fixing where you are.
I hope that after reading this you will be more careful with the representatives of the cat family.

The cat swims in the bath

They are able to gnaw through steel, eat huge crocodile or bite through the thick skin of a hippo... Let's look into the mouth of those who are capable of this thanks to their powerful jaws.

Photos and text by Alexey Osokin

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 big 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.

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 5.4 meter large white will have 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.

We bring to your attention the ten animals with the strongest bites in the animal world. There are animals that would most likely fall into this top ten, but the strength of their bites has not yet been measured due to the complexity or high cost of measurements. Eg, White shark, which should have the strongest bite, but accurate measurement it does not exist except for theoretical estimates. Tasmanian devil has the strongest bite relative to its size - 13.6 atmospheres (14 kilogram-force per square centimeter), which is only a little more than that of hyenas.

10. Leo
42 kgf per sq. cm

An unexpectedly low place for the king of beasts. Lions are the only social felines in the world. They almost always hunt together, which is probably why they didn't have to develop strong bites during their evolution. Another reason may be that they kill their prey by biting the trachea, which does not require a strong bite. Lions hunt at any time of the day, but most often at night. They can go five days without water, but prefer to drink daily if possible.

9. Tiger
74 kgf per sq. cm


Tigers are the largest members of the cat family and hunt alone. The sizes of tigers reach 3.3 meters and weigh about 300 kilograms. They hunt mainly at night. Like lions, they usually kill their prey by clutching the throat, thereby blocking the flow of blood and air. They have a strong bite that is almost twice as strong as a lion's bite. On this moment the number of tigers in captivity is greater than the number of wild tigers. They usually avoid humans, but in some conditions they may attack humans and livestock.

8 Spotted Hyena
77 kgf per sq. cm


Hyenas have one of the strongest bites in the animal kingdom - 77 kgf per square centimeter. With their bite, they can even bite the bones of giraffes. Most likely, the fact that hyenas are scavengers determines their strong jaws. To get to the bone marrow, which is not of interest to large predators, you need strong jaws.

Although hyenas look like dogs, they are actually closer to cats and belong to the feline suborder, not canids. Hyenas can kill a dog with one bite. Despite popular belief, hyenas still hunt themselves, and lions, ironically, often steal prey from them. Like lions, hyenas are social animals.

7. Grizzly
84 kgf per sq. cm

This subspecies brown bear residing predominantly in North America, is known for its enormous size and aggression. Despite their size, grizzlies can reach speeds of 56 kilometers per hour. Mostly grizzlies eat nuts and berries, but sometimes they hunt. In Yellowstone National Park for example, they prey on other animals.

Grizzlies are considered more aggressive than other bears. This is due to the fact that, due to their size, they cannot climb trees, and therefore they have developed such a kind of protective mechanism. In addition to aggression, during the course of evolution, grizzlies have also developed strong jaws that help them defend themselves against wolves and other predators. Grizzlies weigh between 300 and 500 kilograms. They can be dangerous to humans if they come across a mother with cubs, but grizzlies do not consider humans as prey.

6 Gorilla
91 kgf per sq. cm

Gorillas eat plant food, so it's strange to see them in this top ten. In fact, there is little surprise here. Gorillas feed on plants as tough and durable as bamboo - for this they had to develop strong jaws and neck muscles.
Gorillas used to be seen as big scary beasts, but in Lately increasingly they are seen as "gentle giants". They are our closest relatives (closer only to chimpanzees), and their population is rapidly declining (only 700 mountain gorillas remain in the wild). Gorillas can climb trees, but most often they prefer to be on the ground. They usually live in communities of 30 individuals, led by a dominant old male. Gorillas are predominantly delicate creatures and do not pose a danger to humans.

5 Hippo
128 kgf per sq. cm

Hippos are large and strong representatives of herbivores. They are one of the most feared animals in Africa. Hippos are aggressive and defend their territory by capsizing small boats and attacking humans. The bite of a female hippopotamus was measured, as the males are too aggressive, but even the force of her bite reached a huge value of 128 kgf per square centimeter. The word "hippo" comes from Greek and means "water horse". The closest relatives of hippos are whales and cows. They belong to the artiodactyl order, which also includes horses, camels and goats.

4. Jaguar
141 kgf per sq. cm


Jaguars have the strongest bite among felines and mammals in general. They live mainly in the North and South America. Jaguars kill with a bite to the head of the victim. Like many other big cats, jaguars hunt alone. Jaguars have been known to kill anacondas and caimans. Jaguar bites are so strong that they can even bite through the shell of a tortoise. The word "jaguar" comes from the language of the American Indians and means "killing with one jump." Although smaller than their African and Asian relatives, jaguars are the largest felids in the Americas.

In the southern United States, jaguars are thought to have disappeared for over 100 years, but recently there have been rumors that their population in Arizona may develop. The largest number Jaguars live in Belize, in the Cockscomb Basin.

3. Mississippi alligator
149 kgf per sq. cm


The Mississippi alligators are one of only two species of alligators that have survived (the other being the Chinese). Their population currently stands at 5 million individuals, of which 1.2 million live in Florida. Their natural ranges are Florida, Texas, Louisiana, North and South Carolina, Georgia and Alabama. Crocodiles also live in these areas. They feed mainly on fish, turtles and small mammals. In a recent National Geographic study, an alligator bite was estimated at 149 kgf per square centimeter, but their bites can be even stronger, since this study did not measure the largest member of the species.

2. Salted crocodile
260 kgf per sq. cm


Saltwater (or saltwater) crocodiles have the strongest bite of any specimen in the National Geographic study. True, they did not choose the largest crocodile either. If you estimate the bite force of the largest crocodiles, you will most likely get a bite force of 500 kgf per square centimeter.

The range of combed crocodiles runs from eastern India to southeast Asia and northern Australia. Their "diet" includes buffaloes, fish and even sharks. Australians affectionately call these crocodiles "salts", but there is nothing gentle about these giants. They are responsible for more attacks on humans than any other crocodiles (other than the top ten).

1. Nile crocodile
352 kgf per sq. cm


In a National Geographic experiment, the bites of Nile crocodiles were weaker than those of saltwater crocodiles, but most other sources state that Nile crocodiles bite with a force of 352 kgf per square centimeter. Nile crocodiles usually about the same size as combed ones, and have the same bite force. Both of them can take first or second place in this list, since it is difficult to choose which individuals to test and difficult to get how to conduct the experiment correctly.

Nile crocodiles mainly feed on fish, but like their relatives, they will attack any animal that is nearby, such as zebras, birds and small hippos.
