This video shows the moment a hippo burst through the surface of the water after pursuing a speedboat that was moving through the Chobe River, Botswana.
Hippos, despite looking less than athletic can easily outrun a human, charging up to 19 mph on land. Adult hippos are more dangerous in Africa than lions, killing up to 3,000 people every year.
There's nothing like getting too close for comfort when you're far away from land!
