Strongest Bite Force in the Animal Kingdom (Ranked by PSI)
The saltwater crocodile has the strongest measured bite force of any living animal at around 3,700 PSI. Here are the hardest-biting animals on Earth, ranked.
Global Animal Guide · June 9, 2026
Quick answer
The saltwater crocodile has the strongest measured bite force of any living animal, at roughly 3,700 PSI (pounds per square inch). It is followed by the Nile crocodile, the hippopotamus, the jaguar (the hardest-biting big cat), and the gorilla. For comparison, a human bites at only about 150-200 PSI.
Last updated: June 2026 — bite-force figures come from measurements and modelling and vary between studies.
The hardest-biting animals, ranked by PSI
- Saltwater crocodile — ~3,700 PSI. The record-holder among living animals. Its jaws snap shut with crushing force, though the muscles that open them are surprisingly weak.
- Nile crocodile — ~3,000-5,000 PSI (estimated). Africa’s largest crocodile rivals or exceeds its saltwater cousin in some estimates.
- Hippopotamus — ~1,800 PSI. One of the most dangerous animals in Africa, with enormous tusks and a bite that can split a small boat.
- Jaguar — ~1,500 PSI. The hardest-biting big cat for its size. Uniquely, it often kills by biting directly through the skull.
- Gorilla — ~1,300 PSI. A plant-eater whose powerful jaws and teeth evolved for grinding tough vegetation, not hunting.
- Great white shark — ~600-4,000 PSI (estimated). Bite-force estimates vary enormously, but its serrated teeth and sheer size make it one of the ocean’s most formidable predators.
- Spotted hyena — ~1,100 PSI. Strong enough to crack open large bones to reach the marrow inside.
Why PSI doesn’t tell the whole story
Bite force in PSI measures raw pressure, but it isn’t the only thing that matters. Tooth shape, jaw speed, and how an animal uses its bite all count. A jaguar bites with less raw force than a hippopotamus, yet its short, powerful jaws and pointed canines make it a more efficient killer. Sharks like the great white shark rely on serrated, replaceable teeth that shear rather than crush.
Built to crush, built to survive
A powerful bite is expensive to grow and maintain, so it almost always serves a clear purpose: crushing shells and bones, subduing large prey, or competing with rivals. The crocodilians at the top of this list have changed little in tens of millions of years — proof that their crushing bite is a winning design.
