How fast can a bat fly

Mammalian flight speed, after all, paled in comparison to birds. Or so it seemed. In 2016, a paper published by University of Tennessee researchers found that the Mexican free-tailed bat could reach speeds up to 100 mph, making it by far the fastest mammal on earth.

A study published in the journal Royal Society Open Science shows that the Brazilian free-tailed bat can achieve flight speeds of 100 mph (160 km per hour) — faster than those previously documented for any bat or bird.

A. Previous studies suggested the birds fly faster than bats, with the common swift being the fastest bird on record for level flight at 111 kilometers per hour, says Gary McCracken, of the University of Tennessee in Knoxville, as reported in New Scientist magazine.

Some species can fly distances up to 200 miles. To start flying, a bat drops from its perch. If it is on the ground it usually crawls to some height until it can drop into the air.

Lions can run 50 mph

These awesome cats can run as fast as 50 mph and leap up to 36 feet. Because of their lack of stamina, lions can only reach top speeds in short bursts.
