A merciless killer

Crocodiles use their powerful tails to swim at up to 25mph.

In Africa alone there are several hundred crocodile attacks on people each year, up to half of which result in fatalities.

Crocodile attacks are far more common than shark attacks, but because many take place in small and impoverished communities they often go unreported.

Poking a crocodile’s eyes or hitting its nose can save you during an attack because both are sensitive areas.

Crocodiles first appeared 240million years ago and can live for 80 years.
