KEY POINTS

  • Nile crocodiles are estimated to kill about 200 people each year and have the strongest bite in the animal kingdom
  • Great white sharks possess multiple rows of teeth and are capable of ripping chunks of flesh off their prey's body
  • Hippos have the strongest jaws among herbivores

The average strength of a human bite is said to be about 162 pounds per square inch (PSI). This force, however, is no match to the horror that is a Nile crocodile's bite.

Lurking in sub-Saharan Africa is a 20-foot-giant with jaws unlike any other. The Nile crocodile can weigh up to 1,650 pounds and is often found in rivers, freshwater marshes and mangrove swamps in Madagascar and the Nile Basin.

Though its diet mainly consists of fish, it tackles and devours almost anything that crosses its path, according to National Geographic.

Crocodiles are known to have the strongest bite in the animal kingdom, with the Nile crocodile surpassing the bite force of any other living creature in the world. With a PSI of about 5,000, its bite is eight times more powerful than that of a great white shark, Science Focus reported. This force is also estimated to be 15 times stronger than the bite of a Rottweiler.

Estimates have found that the Nile crocodile kills about 200 people each year, National Geographic noted. As carnivores, they will not hesitate to feed on any living animal found within their hunting grounds -- unfortunate humans included.

The predator is said to be aggressive and extremely territorial and relies heavily on stealth and ambush. These crocodiles are capable of eating up to half of their body weight at a time and can survive for months without food, according to the Africa Wild Trails.

Nile crocodiles aren't the only predators to be feared. Great white sharks are regarded as a terror in the ocean, and for good reason too. With a bite force that could potentially reach up to 4,000 PSI, the animal can rip chunks of flesh off its prey's body in just one bite due to its razor-sharp teeth.

Great whites can grow up to 20 feet long (three times the size of a human), according to Ocean, and possess multiple rows of teeth.

Following closely behind the jaws of a great white shark is the hippopotamus, with a bite force reaching 1,800 PSI. This animal's jaws are the strongest of any herbivore on Earth and can crush a full watermelon like a grape without even breaking a sweat.

Aside from their mouths that can open 180 degrees, hippos are characterized by their tusks that can grow up to 2 feet long. According to Popular Science, one bite from the massive creature can break a 10-foot crocodile in half.
