Which animal is the fastest?

A cheetah is the fastest animal. The cheetah is found mainly in eastern and southern Africa and a few parts of Iran. The cheetah is characterized by a slender body, deep chest, spotted coat, a small rounded head, black tear-like streaks on the face, long thin legs and a long spotted tail. Its lightly built, slender form is in sharp contrast with the robust build of the big cats, making it more similar to the cougar.

Though taller than the leopard, it is notably smaller than the lion. Typically yellowish tan to greyish white, the coat is uniformly covered with nearly 2,000 solid black spots.
