You might be surprised when it comes to learning what the fastest land animal on Earth is. It turns out that a tiny mite holds the new record for running speed as measured in body lengths per second. In fact, this measure shows that the mite runs 20 times faster than a cheetah.
The mite in question is called Paratarsotomus macropalpis. It's no bigger than a sesame seed, but can run up to 322 body lengths per second. In comparison, a cheetah running at 60 miles per hour only runs at about 16 body lengths per second.
