Crocodiles kill around 1,000 people per year and Nile crocodiles – found mostly in Egypt – are the deadliest, with an estimated 200 people falling victim to their prehistoric-looking jaws each year. But they don’t set out to hunt humans – it’s simply that to a croc lurking in the river, pretty much any flesh is fair game, from fish to zebra. And few stand a chance. The reptiles weigh up to 1,650 pounds (748kg) and are capable of biting with a force of 3,700 pounds (1,678kg) per square inch, rivaling the jaws of a T. rex.
