From sharks to alligators to bears, there are a variety of animals on our planet with dangerously sharp teeth and powerful jaws. Some animals you might not expect to make this list, like gorillas, which primarily eat plants, but others are renowned predators, like jaguars.

Measuring the bite force of an animal is no easy feat, and while some of these numbers have been recorded in scientific studies, others are estimates or have only been recorded once. Regardless, all these animals have extremely powerful biting capabilities.

There are a few different ways in which an animal's bite strength can be determined. Some studies measure force, others measure pressure (the amount of force applied over a certain area), and some take into account body mass in proportion to force. While Tasmanian devils don't make the top 10 list for strongest bite, they do have one of the strongest bites in proportion to their small size.

Despite the size and strength of the animals on this list, many are considered vulnerable or endangered. IFAW is working with people around the world to protect wildlife, by preserving habitats, fighting wildlife crime, and advocating for policy decisions that benefit animals and people.
