If you have ever been walking through the woods and worried about what animal has the strongest bite, you may just be safer in the woods than a swamp. While any animal bite can be scary, wild animals may seriously endanger your life. If you have ever been nipped by a domestic dog, cat or your pet hamster, this is nothing compared to the bit of a wild animal. Animal bites are actually measured in “pounds per square inch”  (psi) which is the force that their jaw closes down when biting. The weight of the animal delivering the bite is also taken into consideration. These two factors will give you the bite force of an animal. To put what animal has the strongest bite into perspective, a domestic dog has a bite force of around 200 to 300 psi. There are wild animals out there that deliver a much more powerful bite. Come and find the strongest bite force in animal kingdom!

What Animal Has the Strongest Bite?

Our top contender for the strongest bite force is actually a crocodile. They are known for one of the strongest bite forces among all living animals. It is believed that their bite force may rival that of a T. Rex.

Saltwater Crocodile

Bite Force: 3700 to 7700 psi

Average Size: 17 feet (male)

Average Weight: 1,000 pounds

Average Life Span: 70 years

Found in: Brackish and fresh water in eastern India, southeast Asia and northern Australia

The saltwater crocodile, the largest living crocodile on earth is the most likely animal to eat humans. These very large animals feed on monkeys, sharks, water buffalo and wild boar. They have an ability to leap from the water using their tail as a spring, grab their victim in their jaws, dragging it under water and drowning it.

The saltwater crocodile has a jaw force that can crush a full grown cow's skull with its jaws. This animal has an incredibly strong bite force because of the nature of the jaw structure. The skull contains a very large and stiff jaw muscle that resembles bone when touched. This muscle is so hard that it almost blends in the actual skull. It is situated for clamping and contrary to what you might think. They actually have a harder time opening their jaws than closing them.


Nile Crocodile

Bite Force: 5000 psi

Average Size: 16 feet

Average Weight: 500 lbs

Average Life Span: 45 years

Found In: Swamps and freshwater marshes in the Nile Basin, Madagascar Rivers and Sub-Saharan Africa

This is Africa’s largest crocodile and has a reputation as a man-eater. They usually dine on fish, but have been known to attack anything in their way like zebra, hippos, cheetah, jackals, birds and even lions. They do have teeth, but they do not use them to tear the flesh of their prey. The teeth are used for holding the pretty in place. It is the force of the jaw that grips their dinner and pulls it into the water for drowning and dining by other crocodile.


American Alligator

Bite Force: 2125 psi

Average Size: 10 to 15 feet

Average Weight: 1,000 lbs

Average Life Span: 35 to 50 years

Found In: Mostly swamps, rivers, marshes and lakes in the southeastern United States. Heaviest population in Louisiana and Florida and sparsely in other states

Interestingly enough, there are only two species of alligator in the world and the American alligator is one. The other surviving species is the Chinese alligator. Their diet is mostly made up of snakes, turtles, fish and other small animals. They have been known to eat humans and pets. These alligators have very sharp teeth along with powerful jaw muscles that grab prey. They can sometimes prey and bite humans and often cause severe injury and infection.

Other Animals with Powerful Bites

When looking at what animal has the strongest bite, it is also important to consider other animals that can deliver powerful bites. Here is a list of a few animals to steer clear of when you’re out and about in the wilderness.


The Jaguar has a bite force of 700 psi and can pierce the skulls and brains of any animal it preys on. They kill by primarily biting the head and the bite is so powerful that it can even pierce the shell of a turtle.



The hippopotamus delivers a bite with a whopping bite force of 1, 821 psi. The hippo’s closest cousins are cows and whales. They are actually herbivores, but aggressive and territorial by nature. 



Gorillas are vegetarian, but can deliver quite a bite. They are gentle and non-threatening, but their jaws are designed to chew through tough plants like bamboo stalks. Their bite measures 1,300 psi. This comes from powerful jaw and neck muscles.


Grizzly Bear

These bears are omnivores, meaning that they eat both meat and plants. They tend to be very aggressive, but not hunt all the time. Their powerful jaws can bite with 1,250 psi. They are only dangerous to humans if they have cubs. They have very big incisor teeth that can rip apart flesh, but they often just pick and eat berries.


Spotted Hyena

The Hyena delivers a bite with 1,100 psi. They have a very strong jaw that can crush the bones of a giraffe. They are predators and tend to go after the bones that other predators have left behind.



This species of cat is a hunter by nature. They hunt during the night and bite with 1,050 psi usually at the throat of the prey. This bite is twice the bite force of lions. Their teeth are very strong and the powerful jaws can strangulate their prey.


Great White Shark

The movie “Jaws” caused a huge outpouring of fear for these sharks. There has also been a rise in the number of documented shark attacks on humans in recent years. While the great white shark only delivers a bite force of 669 psi, only a little more than a domestic dog. The actual damage from a shark bite is they have very sharp teeth that rips flesh apart.

    Are You leaving Lions out?
  • kiran Moses Nov.16 10:21
    I thought that hyena was the animal with the strongest jaws.
  • miss rizzyOct.28 05:34
    the crocodile is the animal with the strongest bite
  • Nicholas WelchMay.23 18:47
    A hippo has like 12,000 to 15,000 bite force sooooo..... This guy is stupid
  • DarrenMay.3 20:52
    Load of rubbish. I have an old shark survival video and the bite psi of a mako shark was 8,000lb psi

    sharks have gills and animals don't "schoolboy error "
  • LickerpoetApr.5 16:37
    @ : No animals have gills? Then what is a fish? A vegetable?

    What a load of bullshit, rosswind idiot. Tiger hold the record of biggest bigcat canine, generally tiger and lion skull are similar in every aspect, but again, the biggest and heaviest bigcat skull ever recorded by scientist belong to tiger. Anyway, bigger skull doesn't really mean bigger bite force. What determine the bite force is the ratio of skull weight and muscle. Jaguar have smaller canine and smaller skull than both lion and tiger, but their bite force was recorded and accepted by many expertiesto be stronger than both lion and tiger. In conclusion, tiger could have stronger bite force than lion or Vic versa, it's individual cases, but tiger theoretically, is going to have a bigger bite force than lion due to the fact that they hunt more than lion = jaws muscle are more used.
  • The killer whale or orca have also very POWERFUL bite force it be estimated about 5 times the great white which is 3000 psi
  • christianDec.11 01:20
    the black piranha has stronger bite force than great white
  • bigsharkdudeApr.4 01:45
    @ : It's the strongest in the world stronger than a T. rex

    A LON'S BITE FORCE IS AT LEAST SIMILAR BUT COULD BE GREATER THAN A TIGER The old lion's bite force measurement was done on a young lion and compared with a full grown tiger. Since weight is related to force bite, tests should happened between equal sizes and age cats. Was this an honest conclusion? There is the motivation factor to consider too. Because lions are social animals they grow slower and get to maturity later than tigers. The measurements was only redone a few years ago. The new measurements shows that hyenas, lions, and tigers all have about the same bite force of 1,000 psi (National Geographic 2012) In contrary to other predators, it's is very difficult to measure the mature male lion's true bite force. Science only found out lately that lion's only used the bite force needed. The lion is very energy conservation minded. He as a tendency to preserved his canines and needed a great motivation to used a greater bite force. Lions have the particularity of sparing the life of small animals, they usually don't bother hunting them unless very hungry. Knowing this, a small piece of meat his not a great motivation for a big lion even more if he is not very hungry to make an accurate bite force measurement. The more hungry the lion and the larger the piece of meat would motivate more an adult male lion than a little snack. Since the lion's canines are close to 300 psi stronger than the tiger's, it is very prudent to say that in theory a very motivate male lion bite force may well pass the 1,000 psi. THE LOGIC A lion's skull is in average larger than a tiger's, in theory there are more space for muscles. The lion vs. tiger bite force big differences had no sense, particularly with the fact that male lions are large preys specialists. Being said, in combat between two powerful big cats, the bite force and canine sizes differences is a very little to no factor at all. CANINES SIZE You will found many contradictions about the lion's and tiger's canine size. In lions and tigers, the length of the canines are individual. It is not specific to a specie. However, the base of the lion's canines are wider and proven in laboratory to be about 300spi more solid.
