What Animal Is The Fastest?

I think it is the cheetah.

Yeah it is the cheetah I HAVE A WILDLIFE BOOK.

The fastest land animal is the cheetah, who can run around 60 or 70 miles per hour, but only in short bursts. The fastest bird in flight is the peregrine falcon, who can fly around 120 miles per hour for long distances. The fastest water animal is the sailfish, which can swim about 70 miles per hour. There are other animals and insects that hold "the fastest:" records, such as the fastest wing beats, the fastest evolving, the fastest mating speeds, fastest burrowing animal and so on and so forth. I hope you were just looking for a general answer and that I have answered that question.
