What is the Fastest Animal in the world? science and knowledge

If you asked About fastest animal in the world? what would you answer? Cheetah?
If you answer like that, you are wrong answers.
Why? Not that one big cat species that live on the African plains had a super running speed of 70 mph (114 km / h)?
Assuming you are wrong. There are even faster, ie a bird whose name is The Peregrine Falcon (Falco Peregrinus) with a recorded speed: 242.3 mph (390 km / h)! Much faster than a cheetah.
Unfortunately, populations of animals that have spread throughout the continent except Antarctica threatened with extinction due to destruction of habitat in which they live by human activity.
