Which animal do you think has the strongest bite? A lion? Hyena? Turtle? Or maybe someone smaller, like a piranha? The answer may surprise you. There is a famous saying that says: "A big fish eats a small fish" and if you look at how nature works, there is a lot of truth in this statement. It is especially true in the animal kingdom, where most animals survive using a wide range of tactics and evolutionary characteristics. As you probably guessed by now, bite strength is one of the many characteristics that help animals not only in their search for food, but also in self-defense. It is for this quality that today we will compile a list of the most "successful" representatives of the animal kingdom. Bite strength means a lot - from the beautiful Siberian tiger to the terrifying polar bear, here are the 25 most powerful bites in the animal kingdom.
25. Killer Whale, PSI: 19000 ~ Unknown
Until now, it has been impossible to accurately measure the bite force of a killer whale. However, based on incidents involving captive killer whales, it can be assumed that their bite force could exceed 19,000 PSI. Since this is just a guess, the killer whale is only getting 25th place at the moment.
24. Piranha, PSI: Unknown 
If we talk in the context of boxing, then the piranha would have come out as the absolute champion in its weight. The force of her bite exceeds her body weight by 30 times, it is simply unheard of in the animal kingdom. However, her exact strength has never been measured.
23. Leopard, PSI: 300-310
The leopard is one of the five "big cats" of the panther genus and is found in many parts of the world, such as parts of sub-Saharan Africa, Western Asia, the Middle East, South and Southeast Asia and even Siberia. Known for its athleticism and speed, the bite of a leopard is definitely something to avoid.
22. Tiger shark, PSI: 325 
This marine animal is arguably one of the ocean's most deadly predators, and it certainly looks very intimidating. However, her bite strength is only 325.
21. Hyena dog, PSI: 340
The Hyena Dog is endemic to sub-Saharan Africa and is considered the largest of its kind in Africa. Do not let her appearance deceive you, in terms of bite strength, she can compete with cougars.
20.Puma, PSI: 350
The cougar is considered the largest wild land mammal in the Western Hemisphere and one of the fastest animals. They do not have the strongest bite, however, they have muscular jaws and long fangs that are adapted to bite into meat, tendons and muscles.
19. Wolf, PSI: 406
The wolf is one of the most famous and well-studied animals. They also have some of the most paradoxical relationships with humans. The wolf is a great hunter, they usually hunt in packs to overwhelm animals that are much larger than them. The wolf boasts an impressive 406 PSI bite force.
18. Mastiff, PSI: 556
The Mastiff has the strongest bite of any domesticated dog. Not even a Rottweiler, Pit Bull or German Shepherd can compare with him.
17. White Shark, PSI: 669
Although sharks should generally have the strongest bite of any fish, this shark's bite is surprisingly weak. However, this may be due to the fact that sharks do not need a strong bite, as they do most of the damage with their teeth.
16. Leo, PSI: 691
It was sad to see the "king of beasts" in such a low place, but it is obvious that his bite is not his main advantage. However, lions have a fairly strong bite, which has secured them a spot on this list of the 25 most powerful bites.
15. Jaguar, PSI: 700
The jaguar is terrible not for its powerful bite, but for the way its teeth are constructed: they can pierce the skull and are able to pierce the shell of a turtle. For comparison, jaguars have the strongest bite in relation to body weight among the entire feline family.
14. Brown bear, PSI: 850
The humble brown bear lives in forests and mountains in northern North America, Europe and Asia. It is the most widespread bear in the world with an impressive bite force of 850 psi.
13. Kodiak, PSI: 930
Kodiak lives on the islands of the Kodiak archipelago in southwestern Alaska, from which it borrowed its name. It is the largest subspecies of the brown bear and one of the two largest representatives of the bear genus. The second is the polar bear.
12. Amur tiger, PSI: 950
Amur tigers have not only incredibly powerful jaws, but also very sharp teeth, with which they dig into the throats of their victims.
11. Snapping turtle, PSI: 1000 
According to a bite strength test done by Dr. Brady Barr of National Geographic, the snapping turtle has a bite strength of approximately 1000 PSI.
10. Bengal tiger, PSI: 1050
Bengal tigers are the largest felines and are renowned for their strength and power. Despite their formidable reputation, most tigers avoid humans, but the few that do not are responsible for many deaths in India where they live.
9. Hyena, PSI: 1100
This not very cute and scary animal, which we learned about in childhood while watching The Lion King, has teeth that are specially adapted for eating rough food, as well as crushing and digesting large bones. Their milk is high in calcium due to the sheer amount of bones in their diet.
8. Polar bear, PSI: 1235
Polar bears are some of the strongest and toughest mammals on the planet, and as such, they also have a very powerful bite. Their diet consists mainly of seals, which are by no means soft skin, but their teeth are also adapted for a vegetable diet.
7. Grizzly bear, PSI: 1250
The grizzly bear is a majestic and dominant symbol of wild and primordial strength. They are omnivorous and have very strong teeth. Their incisors are relatively large, as are their canines. Unlike most other animals, their teeth are also adapted for a vegetable diet.
6. Blunt shark, PSI: 1250 
Blunt sharks have the strongest bite of any fish, but their strength is only half as strong as they also have very sharp teeth.
5. Gorilla, PSI: 1300
The teeth of typical male gorillas are white and large, but not very sharp. However, they have a very strong neck and jaw muscles which make their bite very strong.
4. Hippopotamus, PSI: 1821
Hippos may not look like they have a strong bite, but the truth is that these huge animals have very strong jaw muscles. Despite the fact that they are herbivores, their bite is considered to be the strongest of all mammals.
3. Mississippi Alligator, PSI: 2125
The Mississippi alligator is a rare endangered animal breeding success story. This species was saved from extinction. The Mississippi alligator is one of the most vicious and deadly carnivores in the world, and its bite is the third on our list.
2. Nile crocodile, PSI: 5000
The Nile crocodile has a well-deserved reputation as one of the most vicious cannibals in all of Africa. The exact number is difficult to say, but it is estimated that about 200 people die in the mouth of the Nile crocodile every year. It ranks second on our list.
1. A combed crocodile, PSI: 7700
To put it bluntly, the combed crocodile is the largest reptile living on our planet at the moment. It is also the largest land and coastal carnivore in the world. The length of the males of this species can reach 6.7 meters, and the weight is 2000 kilograms. They also have the strongest bite of any animal in the world.
Thanks to the work of dog breeders, today there are more than four hundred dog breeds. Some representatives, for example, the Pekingese, saw the rise and fall of ancient empires, while others appeared more recently. A special place is occupied by guard dogs, they are timeless and fashionable, people love them as loyal friends and reliable guards.
Choosing a breed of dog that will play the role of "security" or watchman at home, special attention is paid to speed, distrust, the ability to make independent decisions. Not least is the moment who has the strongest jaws. What breed of dog has a powerful bite that can stop an intruder?
Not by 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 a guarantee that they will be used. There are breeds in which aggression is genetically absent - Labrador, Golden Retriever. Although they are not inferior in strength and mass to the German Shepherd, these dogs are not capable of attacking humans.
Among the representatives of guard breeds, it is rare, but still there are good-natured specimens that do not cope well with the protection of 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 to awaken the inherent potential.
Bite anatomy
Basically, a dog is a construction of bones and muscles. Considering it from a purely engineering point of view, you can determine which breed of dog has the strongest jaws. There is a clear relationship between physiological characteristics.
To "bite" the pet must have a massive head with a large mouth. To maintain balance, such a muzzle should be attached to a short neck to reduce stress on the spine. The optimal ratio is the cranial and jaw regions of equal size. In this case, the capture turns out to be quite deep and strong. In breeds with an elongated muzzle, for example, Russian canine sighthounds, with the strength of the chewing muscles equal to the Doberman, this is why the bite will lose.
The short jaws of bulldogs have great strength, but due to their special structure, they have a so-called "death grip". Decreases the grip and bite area. Breeds with a shortened nasopharynx have a weak sense of smell, and grabbing onto an enemy, they lose maneuverability and become vulnerable. It is difficult for them to bounce quickly.
Golden mean
Knowing the aspects affecting the bite, one can understand that the strongest jaws are in 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 in battle. It was this rule that people were guided by, breeding protective guard breeds to protect a person and his property. In addition, guard dogs are required to have a calm disposition, be easy to train, and be loyal to the owner's family. An overly excitable dog does not respond well to commands and can turn from a defender into a source of problems.
The strongest jaws in dogs. Top breeds
There are breeds that are recognized as the best guards. They have the power of a bite and the desire to protect the owner, his property successfully complement each other. Some of them appeared in the course of life, nature itself was the main breeder, living conditions did not allow puppies with insufficiently strong jaws and character to survive. Others were bred by man, but they are not inferior in guard qualities and the ability to prove to the enemy of the owner with his teeth that he had done a stupid thing by encroaching on his property.
The strongest jaws in this breed are combined with large body sizes. The growth of a dog at the withers is from 70 cm and more.
In addition, the blood of shepherd and fighting breeds flows in the representatives of the CAO, which makes them vigilant, but level-headed guards. Nature carried out selection under 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 the 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 "strangers".
You can safely entrust the child to them, the kane will lay down his life to protect the master's offspring. It is not an easy task to defeat a dog, consisting of 50 kg of iron muscles, possessing agility, fearlessness and incredibly sharp fangs. 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 should 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. It is people-oriented, needs their society. The order is strictly observed in the controlled territory.
Restrained, calm, adequate, independent in decision-making. This breed needs a strict but friendly atmosphere and careful training. Great companion for adults and older children. The Rottweiler is friendly to babies, but may not distinguish between playing with rudeness and react too violently. Compression force - 146 kg.
Excellent scent, lightning-fast reaction, sensitive ears and strong jaws are the distinctive features of the breed. It is worth adding to this remarkable intelligence, love of work and training - and you 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. Teeth pressure force - from 120 to 315 kg.
Don't forget about Pit Bulls, Bull Terriers and American Staffordshire Terriers. The jaw force of these dogs is 120 kg or more. They have a strong grip, quick reaction, extremely maneuverable. It will not be easy to escape them. 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 for sure which breed has the strongest jaw in a dog. There are dozens of breeds suitable for protection in the world. And a representative of any of them in a dangerous situation can set a record that no one will know about.
Recall that 1 atmosphere = 101 325 Pa.
Leo - 40 atmospheres. Oddly enough, the bite of the "king of beasts" is considered not the strongest when compared with other representatives of big cats. However, it is quite enough to hold the prey, and then tear it to pieces.
Tiger - 71 atmospheres. The largest representative of big cats and one of the most impressive predators on the planet. The mass of some Amur tigers reaches 380 kg, and their bite is almost twice as strong as that of a lion. 
Spotted hyena - 74 atmospheres. Hyenas' jaws are among the most powerful among mammals and are specially designed to crush bones. Hyenas easily eat the cleanly gnawed remains of the prey of other predators, even gnawing the bones of a giraffe if necessary. 
Grizzly bear - 81 atmospheres. The largest subspecies of American brown bears are found in Alaska. Their weight can exceed 450 kg, and the jaw strength exceeds that of many large cats. Brown bears usually do not hunt humans, but they often show aggression while defending their territory. 
Gorilla - 88 atmospheres. Fortunately for most of the gorilla's natural neighbors, they are vegetarians. But to protect their group, the largest of the monkeys use not only their paws, but also the most powerful jaws that can bite into almost anything. 
Hippopotamus - 124 atmospheres. Surprisingly, many still consider hippos to be the good-natured lugs from children's books. In fact, these are some of the most dangerous animals in Africa, incredibly aggressive and territorial. With one bite, they can kill a lion or a crocodile, what can we say about a person caught in the tooth? 
Jaguar - 136 atmospheres. The winner in bite strength not only among all big cats, but also among all mammals on the planet. Jaguars are the only predators that kill prey by breaking their skull with their jaws. Moreover, they often hunt cows. 
Mississippi alligator - 144 atmospheres. For crocodiles and alligators, there is nothing more important than a properly delivered bite, so they take three prizes. Mississippi alligators are large enough to attack humans, but they rarely do so, preferring to feed on fish and turtles. 
A combed crocodile - 251 atmospheres. Heavy artillery was used. The largest reptile planets grow up to 7 meters in length with a mass of up to two tons. Sometimes they attack pleasure boats, biting through them. 
Nile crocodile - 340 atmospheres. Those same "big evil crocodiles", because of which children, and not only them, should not go for a walk in Africa. Nile crocodiles are slightly inferior in size to combed crocodiles, but more than compensate for this with a truly monstrous jaw strength. Intense crocodiles can kill and eat even adult male lions, not to mention other savannah predators. 
A shark bite is dangerous because in most cases it is fatal. Shark rarely leaves prey bitten. The evolutionary arms race has provided the bull shark with the widest head and the greatest bite force among others.
“It's all because of the width of the jaws, the bovine has 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 strength in 13 species. “It's not that easy,” they say.
In direct comparison, they received: 2.7 meter bull shark has a bite force of 216 kg, 2.4 meter large white 163 kg.
“A 5.4 meter large white will have a more powerful bite than a 3.3 meter bull, simply because of the size,” says Mott.
A bull shark of the same size will have a stronger bite.
Evolution
How so? The buildup of evolutionary weapons is observed among young individuals. Research shows that a stronger bite is necessary to gain an advantage over other species in being able to capture larger prey at a younger age. The growth of bite strength is fast among juvenile fish, then “leveled off” in adults.
“They feed on murky coastal waters where they must hold on to their prey,” he says.
Some species, such as great whites, prefer to grab and release prey, letting it bleed instead of holding 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 bite has been largely mythical. Based on reports of attacks by bull sharks, great white sharks 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 rigid aluminum tube wrapped in PVC with ball bearings inserted around the outside of the invention. [source: Martin].
Researchers wrapped the device in mackerel and gave it to sharks to eat. Since different types have adapted to different types of food, the strength must be different.
Some species, such as the whale shark (the largest species), have thousands of teeth but do not use them. Instead, they have tissue that filters plankton and small fish right into 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 showed that the average bite force of 22 dog breeds was approximately 26 kg [source: Lindner]. But what about big guys like brindle, bullish, big white? We talked about them above. These are indeed the teeth that do the most damage.
If a person had the power of the blow of a mantis shrimp, he could launch a ball into space!
Most researchers have concluded that the number of deaths from attacks by great white sharks is disproportionately small compared to the number of attacks. Researchers at the University of New South Wales believe this species is dangerous because of its incredibly sharp and frequent teeth, not the strength of its jaws [source: Living Science].
Teeth
Despite their destructive effect, shark teeth are easily lost. They have no bones (supporting structures are made of cartilage), so their teeth do not attach to their jaws. While teeth can break off easily, they have the ability to regrow them.
