Today I want to tell you about the docile, or so it might seem, animal: the hippopotamus. And to show how a hippopotamus is able to fight against a lion, a rhino, a crocodile and even a shark! Hippos are considered the most dangerous animals in Africa, but they pose a danger only to those who are trying to threaten them. It's all about their size and aggressiveness. More people die from THEIR attack than from any other animals (including crocodiles and lions).
