Yeehah cheetah!

A stunning sequence of photos shows a cheetah riding on the back of an antelope on the Kenyan savanna before bringing the beast tumbling to the ground.

The ferocious big cat leapt up and sunk its claws into the hind quarters of the topi - one of the fastest antelopes - hauling it down before his brothers joined in and surrounded the frantic prey.

Renowned for their keen eyesight and dazzling speed, cheetahs are the world's fastest land mammal, reaching speeds of 60mph in approximately three seconds. By comparison, topis are no slouches and can easily reach speeds of over 50mph - but the creature's fleet feet weren't fast enough to save it on this occasion. (Daily Mail)
