World's Deadliest: Crocs Kill With Strongest Bite
CROCODILE PREDATORS

Weighing in at up to a ton, the Nile crocodile is the top predator in Africa's rivers. And that's not all - it has the strongest bite in the animal kingdom, which spells doom for these grazers trying to cross the river.

The mighty crocodile.

Found lurking in the warm waters of five continents.

It looks like an orthodontist's nightmare.

But these gnarly teeth make it one of nature's sharpest predators.

The Nile croc is Africa's biggest reptile-and the top predator in its rivers.

It grows longer than 18 feet and weighs more than a ton.

Crocs have the world's strongest bite.

More than 5,000 pounds of force per square inch.

They use that grip to kill prey-by holding it underwater to drown it.

They have up to 68 teeth-shed and replaced all their lives to keep them sharp.

But the croc's jaw isn't built for chewing.

Instead, crocs grip the carcass and torque their bodies to twist off flesh.

The urge to migrate drives creatures like antelope to venture into the jaws of death.

But there's no hope against a team of hungry crocs.

By feeding together and gripping in unison, they help dismember the carcass.

Mighty as those jaws are, they have one weakness.

The muscles to open the jaws are so weak, you could hold them shut...if you dared try.
