The strongest bite force in the world has been discussed multiple times, as has the strongest bite force of any dog. Now, let’s take a look at the strongest bite force of any animal in the United States. Some of the contestants might come as a surprise to you. Most of the animals’ bite forces in this article are measured by force per square inch, but you must also take into account the size of the animals inflicting the bite force. Some of the smaller animals may have a more impressive bite force than some of the largest animals on the list.
18. Mountain Lion

Mountain lions come in last place on this list, but their bite is much more impressive than a human’s at 162 psi.

Bite Force: 350 psi
Size: 64 – 220 pounds and 2 – 3 feet at the shoulder, with a length of 6.9 – 7.10 feet in length.
The bite force of a mountain lion is more than enough to get the job done, especially when you take into consideration their speed, size, and claws. Mountain lions are also excellent at stalking, which is how they are able to land such hefty prey. They also sneak up on their target on foot, by swimming, and in trees, which makes knowing where to look difficult, especially in the dark.
17. Grey Wolf

Bite Force: 406 psi
Size: 66 – 180 pounds, 30 inches at the shoulder, and up to 6 feet long.
The grey wolf may not have as strong a bite force as some of the animals on this list, but what they lack in bite force, they make up for in other ways. Pack numbers, assisting in the attack, size, and age of the wolf, speed, and power ultimately play into how severe a grey wolf’s attack might be.
16. Humboldt Squid

The Humboldt squid is sometimes referred to as the giant flying squid because it can launch itself out of the water to avoid predators.

Bite Force: 600 psi
Size: 100 pounds and up to 8.2 feet long.
These are certainly some very large and potentially frightening squid, but what can further their advantage in the wild is the number of squids that hunt with them. These deep-sea beasts are armed with lots of sharp teeth, speeds up to 15 mph, and a whole bunch of sticky suction cups. They are also sometimes called the red devil squid because they change to a bright red color when caught or evading predators. They really aren’t someone you want to mess with.
15. Cane Corso

The Cane Corso is a massive dog with huge jaws that ranks higher than the mountain lion on this list.

Bite Force: 700 psi
Size: 88 – 110 pounds, 23 – 28 inches at the shoulder, and 41.5 – 55 inches long.
The cane corso is a very large dog with an impressive bite force, though it isn’t too far from the strongest bite force of a dog, belonging to the Kangal at 743 psi. The Corso is a dog that requires specific training and handling to ensure the safety of the owner.
14. American Bandogge

American Bandogge is a cross between an American pitbull terrier and a mastiff, or an American bulldog and a mastiff.

Bite Force: 730 psi
Size: 85 – 150 pounds, 25 – 29 inches tall at the shoulder, and 22 – 33 inches long.
The American bandogge is simply a mixed-breed dog with a very powerful bite. The breeds used to create it are known to be affectionate and very protective. Specific training is important for these types of dogs, as is the education of the owner on what it takes to ensure the health and happiness of one.
13. Kangal

Kangals have the strongest bite of any dog breed.

Bite Force: 763 psi
Size: 90 – 145 pounds, 28 – 32 inches at the shoulder, and 37 – 44 inches long.
The kangal is the dog with the strongest bite force. Humans have fought against lions, which would still be an unfair fight because the lion is bigger, stronger, and has claws. These are technically livestock guardian dogs that kill wolves, but have since become pets. They are loyal and gentle, but like all dogs, they should be watched around children.
12. Brown Bear

Bite Force: 850 psi
Size: 180 – 1300 pounds, 2.3 – 5 feet tall at the shoulder, and 4.6 – 9.2 feet long.
The brown bear is not the bear with the most bite force or even the strongest bear, but it ranks close to midway on this list of the top bite forces, which isn’t bad at all. They are enormous and can run at speeds of up to 35 mph, which makes this one a strong and ferocious animal you can’t outrun.
11. Alligator Snapping Turtle

Bite Force: 1,004 psi
Size: 62 – 249 pounds and is 22 – 29 inches long.
Anything with “alligator” in its name is someone you may want to avoid, especially when swimming barefoot! This snapping turtle is massive and enjoys making farm ponds its home, which can be a death sentence for the livestock using the pond.
10. Grizzly Bear

It’s hard to believe a grizzly bear has only a slightly higher bite force than an alligator snapping turtle.

Bite Force: 1,160 psi
Size: 250 – 700 pounds, 40 inches tall at the shoulder, and 74 – 95 inches long.
Grizzlies have a lot going for them in the “things to fear” category. They are massive creatures, with claws that can kill and the ability to run 40 mph in short sprints. There isn’t much that will mess with a grizzly bear except another grizzly bear. With the amount of sheer terror surrounding grizzly bear encounters, one would think they would rank higher on this bite force list. It doesn’t make them much less scary, considering their 2 – 4 inch claws capable of ripping a tree to shreds.
9. Polar Bear

Polar bears may look sweet and huggable, but they are the most dangerous bears in existence.

Bite Force: 1,200 psi
Size: 400 – 1700 pounds, 2.4 – 5 feet at the shoulder, and 8 – 10 feet long.
Polar bears are known to kill humans and can easily take one’s head off with a well-aimed swipe, but they are apex predators doing what they need to in order to survive. These bears can also sprint 25 mph for short distances when needed.
8. Bull Shark

The bull shark is a shark that has laid claim to many unprovoked attacks on humans.

Bite Force: 1,350 psi
Size: 200 – 500 pounds and are 7 – 11 feet long.
What makes bull sharks so dangerous is not necessarily their size or even their bite force; it’s their elevated testosterone levels that make them aggressive. One bite from a bull shark with its razor-sharp teeth is all it would take. They can also swim in bursts of 25 mph. The bull shark and their not-so-distant relative, the tiger shark, are known for their aggression towards humans and make up more attacks on humans than most other types of sharks. Bull sharks have been found with license plates and a myriad of strange, not-so-tasty items in their stomachs, suggesting they will literally eat anything.
7. Jaguar

Known for their massive jumping ability, the word jaguar means “he who kills with one leap.”

Bite Force: 1,500 psi
Size: 150 – 200 pounds and up to 7 feet long.
Jaguars are the biggest cat in the Americas and have a much more severe bite than the mountain lion. These beautiful cats can reach speeds of 50 mph, so you’d better have a better plan than outrunning one. They are also very good swimmers and climbers, making them an excellent apex predator. Jaguars are the big cats with the highest bite force, though they are not nearly as dangerous as their cousins, the tigers. This is mostly due to the tigers’ proximity to humans versus the human-timid leopard.
6. Pacific Walrus

A walrus can weigh as much as a large pickup truck, with males reaching up to 4,400 pounds.

Bite Force: 1,850 psi
Size: 1,800 – 4,400 pounds, and up to 12 feet long.
Walruses aren’t exactly quick on their flippers at 7 mph, but they do have a serious bite for anyone who decides to fight them. They can run at bursts of 22 mph if needed. They fight other males with their enormous tusks, which humans poach them for. These huge creatures prefer to eat mollusks like clams and lie in the sun, or on an ice shelf. In the United States, Pacific walruses can only be seen in the wild along the coastal areas and islands of Alaska.
5. American Alligator

Any standing body of water in Florida could house a gator, making swamps, rivers, lakes, and drainage pools all potentially dangerous.

Bite Force: 2,125 psi
Size: 9 – 15 feet long, and up to 1,000 pounds
There is a good reason why alligators have been in the world for so long, and it isn’t because they are weak or slow. These enormous lizards can run up to 25 mph on land and swim 20 mph, which is faster than the bottlenose dolphin. The alligator can chomp animals or humans with its impressive bite force and snap our bones like twigs, literally. They can also bite through steel. These clever and mega stealth reptiles have another trick up their swampy sleeve, like their cousins the crocodile, they can snap down on a human’s leg, then go into the destructive death spin, and then drag the victim to the bottom of the bayou and drown them. Many times, a limb comes off when a gator goes into a deadly spin.
4. American Crocodile

The crocodile won’t win any races but they can run up to 10 mph and swim 20 mph, making them even more terrifying.

Bite Force: 3,700 psi
Size: 300 – 2000 pounds and is 8 – 20 feet long
The American crocodile is one Florida creature that tops even the bull shark and alligator in bite force. Once their mouth is shut, it is next to impossible to force it open. They even swallow rocks to aid with digestion and help them sink to the bottom when in water. The bite force of a Tyrannosaurus rex is currently estimated at around 8,000 psi. The prehistoric “limosine crocodile’s” bite force of 23,100 psi is more than the orca and even the least weasel, if it were bigger.
3. Great White Shark

The great white shark is the biggest predatory fish in the oceans.

Bite Force: 4,100 psi
Size: Up to 4,500 pounds and is 11 – 20 feet long.
The great white shark is a top apex predator for its size, speed, sense of smell, and razor-sharp teeth. It can swim in short bursts up to 35 mph. They are not as aggressive as the bull shark but do have one of the top bite forces in the U.S. They also have 300 teeth arranged into seven rows, which is enough to do some deadly damage, even if their bite force is minimal.
2. Orca

The orca is a toothed whale that belongs to the oceanic dolphin family, where it is the largest member.

Bite Force: 19,000 psi
Size: 8,000 – 11,000 pounds and is 18 – 33 feet long
The bite force is an estimated guess by marine biologists and scientists, though it could be even more. The orca has the highest psi of bite force of any other animal in the U.S. They are capable of swimming up to 35 mph, which is the same as the great white. The orca is commonly called the killer whale because it is a whale and is definitely a killer. These whales have been filmed torturing other marine life for fun and have started attacking yachts, which you really can’t even blame them for doing.
1. Least Weasel

This tiny weasel is the animal with the strongest bite force when compared by weight to the other apex predators and strong biters around the U.S.
©Keven Law / Creative Commons – Original
Bite Force: 1,000 psi
Size: 1 – 8.8 ounces, 1.8 – 2.75 inches tall at the shoulder, body length is 4.5 – 7.5 inches long with a tail that measures another .5 – 3.4 inches long, and their width is 1.6 – 2.6 inches.
These tiny mammals are anything but “least” when it comes to bite force and ability to kill animals much larger than themselves. The only other animal with a higher bite force for its size is the Tasmanian devil, which is one you would expect. The least weasel only weighs a couple of ounces and is capable of crushing the spine of prey animals much larger than it is, like; chipmunks, rabbits, mice, squirrels, rats, voles, shrews and whatever else it can catch and take down. Their top speed is 7 mph, which isn’t bad for such a tiny creature.
The least weasel’s bite force is just about the same as that of the alligator snapping turtle. Take into consideration that the alligator snapping turtle weighs an average of 175 pounds, whereas the least weasel only averages 2 ounces. If the least weasel were a bigger creature, we would all be in big trouble.
