Peregrine Falcon is the fastest animal overall. This master raptor achieves speeds over 240 miles an hour (386 kph) when it dives, making it the fastest creature on Earth. Peregrines are light in weight, aerodynamically shaped, and have robust respiratory systems; all of which allows them to be the fastest birds of prey, and animals in general. Peregrine falcon numbers took a massive hit during much of the 20th century in North America. The chemical made the falcon’s—and many other birds — eggshells thinner, preventing the embryos from developing, in addition to poisoning adult falcons.
