Fastest Animal in the World
If you want to know the record holder for the fastest animal in the world, then you're in the right place. If we include birds into this list then the fastest animal in the world is the Peregrine Falcon, a cosmopolitan bird of prey in the family Falconidae. The Peregrine is renowned for its speed, reaching speeds of over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest extant member of the animal kingdom.
The fastest land animal is the cheetah. The cheetah achieves by far the fastest land speed of any living animal — between 112 and 120 km/h (70 and 75 mph) in short bursts covering distances up to 500 m (1,600 ft), and has the ability to accelerate from 0 to over 100 km/h (62 mph) in three seconds. If we include fish, then the Sailfish is the fastest fish. Sailfish has been clocked at speeds of up to 110 km/h (70 mph), which is the highest speed reliably reported in a fish.
