The hippopotamus (from the Greek for “river horse”) is a semi-aquatic mammal inhabiting river, lakes and mangrove swaps. A territorial bull will preside over a stretch of river and groups of 5 to 30 females and young.
Hippos are the third largest land mammal by weight and can weigh between 1.5 and 3 tonnes. Despite its stocky shape and short legs, a hippo can easily outrun a human and they have been recorded running at speeds of 30km/h over short distances. They are regarded as one of the most dangerous animals in Africa.
