If there's one thing a hippo doesn't like it's being interrupted while having lunch. This gamekeeper in Uganda runs for his life after disturbing a hungry beast having its favourite meal of grass. He fled as the angry three-ton beast - which can outrun a man - charged at him.
The keeper, armed only with a walkie-talkie at the Murchison Falls National Park, somehow managed to escape on this occasion. The hippopotamus is one of the most aggressive creatures in the world and is often regarded as the most ferocious animal in Africa. Hippo jaws are capable of biting a 10-foot crocodile in two.
They regularly attack humans and boats. Despite their stocky shape and short legs, they can reach speeds of 30 miles per hour and can easily outrun a human. They are the third-heaviest land mammal. Males can weigh up to 4,000 lbs and measure 17-feet long.
Adults think nothing of taking on crocodiles, which often live in the same pools and rivers.
