Fastest animals in the world

Fastest animals in the world, 10 fastest animals in the world The speediest humans on Earth, including Olympic superstar Usain Bolt  can run slightly more than 23 mph at their fastest. Here's a look at how that stacks up to the world's 10 quickest animals:It can run exceptionally fast, being built for maximum predator evasion through running, and is generally accepted to be the fastest land mammal in the New World. he top speed is very hard to measure accurately and varies between individuals; it is variously

They are the only felid with non-retractable claws and pads that, by their scope, disallow gripping (therefore cheetahs cannot climb vertical trees, although they are generally capable of reaching easily accessible branches). The cheetah, however, 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.
Adaptations that enable the cheetah to run as fast as it does include large nostrils that allow for increased oxygen intake, and an enlarged heart and lungs that work together to circulate oxygen efficiently. During a typical chase, its respiratory rate increases from 60 to 150 breaths per minute. While running, in addition to having good traction due to its semi-retractable claws, the cheetah uses its tail as a rudder-like means of steering to allow it to make sharp turns, necessary to outflank prey animals that often make such turns to escape.
