The 10 Strongest Animal Bite Forces In the World


Highly aggressive and unpredictable, often charges other animals or humans. Weighs between 3,000 to 8,000 pounds, grows up to 14 feet long, and lives for 40 years. Capable of generating 1,800 PSI of biting force.

American Alligator

Teeth and jaws change significantly as they develop. Found in the Southeastern U.S. Lower jaw and teeth fit entirely within the upper jaw, leaving no lower teeth visible when mouth is closed. 

Nile Crocodile

Agile predator that can wait for hours, days, or even weeks to ambush prey. Nile crocodile specimen measured around 8 feet long, but average Nile crocs grow to 16 feet. Bite strength estimated to exceed 3,000 PSI.

Saltwater Crocodile

Largest living reptile, ambushes prey before drowning or swallowing it whole. Weighs 1,000 pounds, with the most powerful bite in the world. Responsible for 3,000-5,000 human deaths per year. 

Great White Shark

Not humans' preferred prey, but responsible for the largest number of unprovoked shark attacks. Bite force difficult to measure accurately, but a 21-foot shark registers approximately 4,000 PSI.

Grizzly Bear

Grizzly bears have a bite force of almost half a ton and 975 PSI of crushing power. They mainly eat nuts, berries, fruit, and vegetation, but can also bring down prey as large as moose.

Spotted Hyena

Spotted hyenas have a bite force of 1,100 PSI, almost double the strength of lions. They hunt in packs and use their bite force to crack bones and consume every part of their prey.

Polar Bear

Polar bears have an estimated bite force of 1,200 PSI, making them the strongest bear species. They primarily eat seals but can also feast on whale carcasses, fish, and berries. Their white fur helps retain heat in the harsh.


Gorillas have a strong bite force of 1,300 PSI. They mainly feed on plants, shoots, and fruit, using their strong jaws and large molars to chew through fibrous material. Gorillas are critically endangered.


Jaguars have the most powerful bite in the Panthera genus, with a jaw power of 1,500 PSI. They crush the skulls of their prey, including turtles, by biting right through them. Jaguars are solitary apex predators.
