What is the fastest animal on Earth?

The fastest animal on Earth is the peregrine falcon (Falco peregrinus), which can reach speeds of over 240 miles per hour (386 kilometers per hour) during its hunting dive, known as a stoop. This incredible speed makes the peregrine falcon the fastest bird and the fastest animal in the world. Peregrine falcons use their speed to catch prey mid-flight, diving from great heights to swoop down on birds and other small animals. They are found in a variety of habitats around the world, from city buildings to cliffs.
