PHOTOS: Shocked Gamekeeper Runs For His Life From 3 Ton Hippo, 2009
"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."
Speaking of hippo jaws:
Wikipedia says hippos are "threatened by habitat loss and poaching for their meat and ivory canine teeth." I guess you can sport spectacular canines and still be an herbivore.
