Why Hippos Are One Of The Most Dangerous Animals

The hippopotamus – fat and cuddly vegetarian or fearsome and aggressive killer? This eye-opening documentary special reveals a shocking side to these almost cartoon-like creatures who are responsible for killing more people in Africa than any other creature. Violence is central to hippo society – female hippos are hugely protective mothers as males often kill their young, and with only one in 10 males ever getting the chance to mate, fights between males are often to the death.
