Well, there’s no doubt about this one. The Cheetah has always been known as the swiftest animal on land. This ‘purring’ member of the cat family is physiologically meant to reach breakneck speeds considering the fact that they have enlarged nostrils, heart and lungs. Cheetah’s are known to reach a maximum speed of an unbelievable 70 miles per hour and a constant speed of 60 miles per hour. One fun fact about the insane speed of this animal it’s running technique which sees the predator stay more in the air than on its feet enabling to cover much more distance.
