Top 5 Strongest Animal Bite Forces in the World


The bite force of an animal is a measure of its jaw strength and can vary depending on factors such as the size, anatomy, and feeding habits of the animal.

Here are five animals known for having exceptionally strong bite forces:

  1. Nile crocodile (5,000 PSI)
  2. Saltwater crocodile (3,700 PSI)
  3. American alligator (2,125 PSI)
  4. Hippopotamus (1,800 PSI)
  5. Jaguar (1,500 PSI)

1. Nile crocodile

The bite force of a Nile crocodile (Crocodylus niloticus) is estimated to be around 5,000 pounds per square inch (psi). This remarkable bite force allows the Nile crocodile to exert immense pressure when capturing and subduing its prey. With their powerful jaws, they are capable of clamping down with great force, making them highly effective predators in their natural habitat. Their bite force, combined with their size and agility, enables them to capture and overpower a wide range of prey, including large ungulates, fish, and other aquatic animals.

2. Saltwater crocodile

The saltwater crocodile, also known as the estuarine crocodile or Indo-Pacific crocodile (Crocodylus porosus), is widely recognized as having the strongest bite force among living animals. It is estimated to have a bite force ranging from 3,700 to 7,700 pounds per square inch (psi), or 16,460 to 34,000 newtons.

The tremendous bite force of the saltwater crocodile allows it to capture and overpower large prey such as water buffalo, wild boars, and even other crocodiles. With their powerful jaws and sharp teeth, they can deliver a crushing bite that immobilizes and dismembers their prey.

3. American alligator

The American alligator (Alligator mississippiensis) is a powerful reptile known for its formidable bite force. It has one of the strongest bite forces among living animals. While the precise measurement of an American alligator’s bite force may vary, studies have estimated it to be around 2,900 pounds per square inch (psi) or approximately 13,000 newtons. This immense bite force allows the American alligator to capture and overpower its prey, which primarily consists of fish, turtles, birds, and mammals. It is worth noting that an alligator’s bite force may vary based on factors such as the size and age of the individual, as well as other ecological and environmental factors.

4. Hippopotamus

The bite force of a hippopotamus, specifically the common hippopotamus (Hippopotamus amphibius), is estimated to be around 1,800 pounds per square inch (psi). This makes them one of the animals with the strongest bite forces in the animal kingdom.

Despite having relatively small jaws compared to their massive size, hippos have large and robust teeth, particularly their incisors and canines. They use their formidable bite force primarily for defense, as their herbivorous diet consists mainly of vegetation.

While hippos are herbivores, they can become extremely aggressive and territorial, especially if they feel threatened or if their young are endangered. In such situations, they can use their powerful jaws and bite force to defend themselves or attack potential threats, including humans.

5. Jaguar

The jaguar (Panthera onca) is known for its powerful bite force, which enables it to deliver a quick and decisive kill when hunting. While specific bite force measurements for jaguars may vary, it is estimated to be around 1,500 pounds per square inch (psi).

This bite force allows jaguars to deliver a crushing bite to the skull of their prey, piercing through the tough hides and bones of animals such as caimans, turtles, capybaras, and other large mammals. Jaguars have robust jaws and well-developed muscles that provide the strength needed for their formidable bites.

The strong bite force of jaguars, combined with their agility and stealth, makes them highly effective predators in their natural habitats, which include dense forests and wetland areas of Central and South America.

Other animals with the strongest bite force are:

  • Gorilla (1,300 PSI)
  • Polar bear (1,200 PSI)
  • Spotted hyena (1,100 PSI)
  • Bengal tiger (1,050 PSI)
  • Grizzly bear (975 PSI)
  • African lion (650 PSI)
  • Gray Wolf (400 PSI)

The bite force of an animal refers to the pressure it can exert with its jaws. The creatures mentioned in this list have developed remarkably strong bite forces as an adaptation for hunting, self-defense, or both. Crocodiles, for instance, rely on their robust jaws to capture and subdue prey, utilizing their powerful bite to secure a meal. On the other hand, hippopotamuses employ their formidable bite force as a means of protection against potential predators.
