The strongest bite. Who has the most powerful jaws? Dogs have the strongest jaws. Top breeds

A shark bite is dangerous because in most cases it is fatal. A shark rarely leaves its prey bitten. An evolutionary arms race has given the bull shark the widest head and greatest bite force of any species.

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

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

In a 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 great white will have more powerful bite than a 3.3m bull, simply because of the size,” says Mott.

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

Evolution

How so? An increase in evolutionary weapons is observed among young individuals. The study shows that having a stronger bite is necessary to gain an advantage over other species in being able to take larger prey at a younger age. The increase in bite force is rapid among juvenile fish, then “levels off” in adults.

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

Some species, such as great whites, prefer to grab their prey and let it go, allowing it to bleed out rather than being held 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 many years, information about the strength of a shark's bite was largely mythical. Based on reports of attacks by bull, great white and tiger sharks, we know that many species produce enough force to dismember a human body. But no exact figures were associated with these facts.

Shark bite pressure study

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 solid 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 sharks to eat. Since different species have adapted to different types food, the strength should be different.

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

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

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

If a person had the punching power of a mantis crab, 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 frequent teeth, rather than the strength of its jaws [source: Live Science].

Teeth

Despite their destructive effect, shark teeth are easily lost. They have no bones (supporting structures are made of cartilage), so their teeth are not attached to their jaws. While teeth can break off easily, they have the opportunity to grow them back.

The main force of a human bite comes from 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 bite force of a person is enough to chew on a cinder block. Amazing, right?

A human being bitten by a human is obvious, but in some cases the victim is unaware
(for example, when the victim was drunk) or does not want to tell others who bit him (for example, because of a hand injury during a fight).

Be careful with cuts above the knuckles if they occur in combat, especially when the cuts were caused by another person hitting the mouth.

Why is a human bite dangerous?

Is it possible to become infected with HIV through a human bite? In addition to tissue trauma, infections due to oral flora are added, this becomes a serious problem for the body.

Everyone knows who cats are. When we hear this word, a picture of a domestic cat happily 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’ll 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 of being an Olympic champion in running? But any “murka” living next door to you may well do so.

2 Have you already climbed higher, where the feline animal cannot reach you? You can get down!

The highest jumps can be made by African leopards and pumas. They are able to jump onto a tree branch (or rock ledge) located at a height of 5.5 meters. In general, cats can jump up to five times their height.

3 Well, did you get chills down your spine? Ah, you don’t have time, is a Bengal tiger 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 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 most strong jaws? Look around.

Yes, yes, that cute tiger that follows you around. Its bite force is 1000 pounds per inch (that's about 450 kilograms). It is impossible to escape from his grip. For those who sit at home and are not threatened by the tiger, 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 (simply bite through it).

Felines' hearing is 20 times sharper than humans'. They can hear sounds inaccessible to us bipeds.

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 find out about it at the very last moment.

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

8 This species of mammal reproduces at an amazing rate, especially the domestic furry subspecies.

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

9 Don’t try to hide from a cat in a dark room or sneak closer to a predator during a night safari!

They have a vision range of 200 degrees, while humans have only 180. And they have more than 20 times more rods in the retina, which are responsible for the ability to see in the dark.

10 I hope the previous 9 facts have already scared you, and your dreams of becoming a trainer large predators or the second Kuklachev left you.

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

1. Let's start, of course, with lions. These are incredibly beautiful and graceful cats- real killing machines. No one can feel calm when they are around them. Lions even attack 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 cannot boast of the strongest bite, but incredibly sharp fangs and incisors leave no chance for the prey...

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 significantly 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 a huge crocodile in two. The bite force of these fatties reaches 125 atmospheres.

7. There are legends about the power of the crocodile’s jaws. And for good reason. These cutest creatures have a bite force of 340 atmospheres and this is the highest among all African animals.

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

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