African Lion
The African Lion is no doubt one of the fiercest predators on the planet. They are not only fearless but they are also fast and strong. In Africa, an average of 250 people dies from African Lion attacks. It is advised that you do not turn your back and run when you encounter an African Lion. In fact, your best chance is to stand your ground and show no fear. If the lion sees that you do not fear him, he will have second thoughts on attacking.

But did you know that African Lions who attack people are actually the sick and elderly ones? African lions prefer feasting on animals over humans but since the older ones are unable to hunt their natural prey effectively, humans are seen as an easy kill and an alternative food source.
