African Elephant
The African elephant is the world’s largest animal and is one you don’t want to mess with. This elephant has been known to trample even a rhinoceros to death. It has the capacity to display bouts of rage and has been a part of activities that were interpreted as vindictive such as razing entire villages.
Cassowary
This massive bird is the deadliest one on earth with its huge talons that are capable of disemboweling a human being. Not only that, but these birds won’t hesitate to act on that strength as they’re known to wander onto beaches and even into homes in search for food. If they don’t manage to find food, they will turn aggressive and fast.
