Stephen Fry narrates a documentary about hippos, the most dangerous animals in Africa and also some of the most bizarre. They spend most of their life in water, but cannot swim. They eat mainly grass, but are not afraid to challenge a lion for its share of a kill. And a three-tonne bull can charge at 30 kph.

But hippo lives are also full of tenderness and even comedy. Show less
