Fastest animal in the world: Peregrine falcons are the

Peregrine falcons are the fastest birds and the fastest animals on Earth today—they reach these top speeds while diving during flight. These birds of prey are quick for their large size. The peregrine falcon is the fastest animal in the world, attaining speeds of up to 240 mph when it dives. The black marlin, a type of fish, is capable of swimming at velocities reaching 82 mph. The peregrine falcon is the fastest animal, reaching 389 km/h. The cheetah rules the land, while a tiny mite is the fastest by body size. As the fastest bird—and by some measures, the fastest animal on Earth—the peregrine falcon is a marvel of nature. With speeds reaching over 240 miles per hour during its hunting stoop (high-speed dive), it easily outpaces even the swiftest of land mammals.
