Dangerous lawnmowers: Hippos

They live in water, but are very bad swimmers. Their home is sunny and hot, but they get sunburnt. They are heavy and lumbering, but are considered one of the most dangerous animals in Africa: the hippopotamus. More amazing facts about these animals? They produce a kind of reddish mucus against sunburn, which works like sun milk and protects their skin. They are more closely related to dolphins and whales than to horses. They are nocturnal and use the cooler hours to mow the shore. Curtain up for the hippos of the German Digital Library!
