Humans seem to have an inherent fascination with speed. We enjoy watching high-performance cars race around tracks—or even pushing speed limits ourselves—and we celebrate Olympic champions like Usain Bolt, who might just be the fastest person currently alive on two feet.
This curiosity often stretches beyond just machines and elite athletes. What has nature done to give certain animals the speed to outpace their prey? And is there truly a definitive fastest animal on the planet?
If our goal is simply to identify which animal can travel from one point to another in the least amount of time, then that famous fact about cheetahs holds up. This slender feline, primarily found in Africa, can reach speeds of 64 mph, which is about the maximum speed allowed on many highways in the U.S. (Some studies even place it at 58 mph.)
These speeds are achieved under perfect conditions. In reality, cheetahs usually sprint when they're hunting, and if their prey tries to escape, the cheetah must stop and restart its chase to stay in pursuit. Because of the unpredictable movements of their prey, cheetahs often maintain speeds closer to 33 mph.
When considering the fastest animal on land in terms of straight-line movement, the cheetah is likely the top contender. However, not all animals rely on limbs for vertical movement. The falcon, for instance, utilizes gravity to dive toward its prey from above. Much like parachutists in free fall, falcons can reach remarkable speeds during their descent. The higher the starting altitude, the faster they can go: A peregrine falcon, assisted by humans from 15,000 feet, has been recorded diving at speeds of 183 mph.
The cheetah also finds competition in the water, where the sailfish outpaces it, reaching speeds of 68 mph as it breaches the surface. To put that in perspective, a sailfish can swim 200 meters in just 10 seconds, while Michael Phelps would require over a minute to cover the same distance. Even Killer whales are swift in the water, reaching speeds of 34 mph—impressive considering their size.
Determining the fastest animal in the world isn't a straightforward question. Humans often equate "fast" with linear movement, like what we see in racing, but in the wild, "fast" can mean something quite different. While you may never witness most of these creatures reach their top speed in person, one domesticated animal is capable of hitting impressive speeds: The greyhound tops out at 43 mph.
