25 Animals with the Most Powerful Bites to Avoid

Posted by , Updated on March 22, 2024

Which animal do you think possesses the most powerful bite? Is it the Lion, Hyena, Snapping Turtle? Or maybe is something smaller like a piranha. The answer, may surprise you. There’s a famous proverb that says the “big fish eats the little fish,” and if one takes a closer look at how nature works, one will see that this is not far from the truth. This is especially true in the animal kingdom where most animals survive by employing a wider range of tactics and evolutionary traits. As you have probably guessed by now, a powerful bite force is one of the many traits that help animals not only in their quest for food, but also in their battle for protection. For that reason, today we’ll rank the most “accomplished” members of the animal kingdom based on what else? Their bite force. From the beautiful Siberian tiger to the intimidating Polar bear, these are 25 most powerful bites in the animal kingdom you definitely want to avoid.



Killer Whale, PSI: 19,000 ~ Unknown

So far it has been impossible to measure the bite force of a killer whale with accuracy. However, based on captive killer whale incidents it’s estimated that their bite force could exceed 19,000 PSI. Since this is mere speculation, the killer whale, for now, comes in on #25 as a special mention.


Piranha, PSI: Unknown

In boxing terms the black piranha would be the absolute “pound for pound” king of the animal kingdom when it comes to bite force. The piranha is able to exert a force of up to thirty times its body weight, a feat that is unheard of in the animal kingdom. However, its exact bite force hasn’t been measured.


Leopard, PSI: 300–310

The leopard is one of the five “big cats” in the genus Panthera and can be found in many parts of the world such as certain areas of Sub-Saharan Africa, West Asia, the Middle East, South and Southeast Asia, and even Siberia. Known for its great athleticism and speed the leopards’ bite is something you definitely want to avoid.


Tiger Shark, PSI: 325

This sea beast might be one of the most deadly predators of the oceans and definitely looks very intimidating but its psi bite force is only 325.

The African wild dog is a canid native to Sub-Saharan Africa and is considered the largest of its family in Africa. Don’t let it’s cute appearance deceive you, in terms of bite force, it competes with cougars.

The cougar, also known as the puma, is considered to be the greatest of any large wild terrestrial mammal in the Western Hemisphere and one of the fastest land animals, period. They don’t have the most powerful bite force but with extremely muscular jaws and long canine teeth which are adapted for cutting meat, tendon, and sinews; you really don’t need that much bite force.


Gray Wolf, PSI: 406

The gray wolf is one of the world’s best known and well researched animals with probably one of the most paradoxical relationships with humans. The wolf is a formidable hunter, normally hunting in packs to tackle animals much larger than itself. It also sports a respectable bite force of 406 PSI.


Mastiff, PSI: 556

The Mastiff has the highest bite force among domesticated dogs. Not the Rottweiler, American pit bull, or the German shepherd.


Great White Shark, PSI: 669

Even though sharks in general are supposed to have the strongest bite among fish, surprisingly the great white’s PSI isn’t all that great. This, however, could be attributed to the fact that great whites don’t necessarily need a strong bite force, because much of the damage they do is inflicted by their teeth.


African Lion, PSI: 691

We were kind of disappointed to see the “king of the jungle” ranking so low but apparently his mighty bite isn’t one of his greatest weapons. However, lions have a strong-enough bite to give them a position in our top twenty-five list.


Jaguar, PSI: 700

The scary thing about jaguars isn’t just their powerful bite force but the way their teeth are constructed: they can pierce through skulls and can also pierce through turtle shells. For the record, jaguars have the strongest bite by far in relation to size among the cat family.


Brown Bear, PSI: 850

This not so pretty and intimidating animal that most of us ’90s kids learned about from watching The Lion King, has teeth that are specialized for consuming coarse food and crushing and digesting large bones.

Polar bears are some of the strongest and toughest mammals on the planet and as such they have a very powerful bite force as well. Their nutrition consists mainly of seals—which don’t exactly have soft skin—but their teeth are adapted for a vegetable diet as well.


Grizzly Bear, PSI: 1250
