10 of the Fastest animals on Earth

1 - Cheetah can accelerate from 0 to 96.6 km/h (60.0 mph) in under three seconds, though endurance is limited: most Cheetahs run for only 60 seconds at a time

2 - Free-Tailed Bat "in flight" can fly upto 60.0 mph.  Tail wind is what allows free-tailed bats to reach such high speeds.

3 - Pronghorn is the fastest animal over long distances; it can run 56 km/h for 6 km (35 mph for 4 mi), 67 km/h for 1.6 km (42 mph for 1 mi), and 88.5 km/h for .8 km (55 mph for .5 mi).

4 - Wildebeest are extremely fast runners, which allows them to flee from predators. They are better at endurance running than at sprinting. It can run 50.0 mph.

5 - Lionesses are faster than males and can reach maximum speeds of 35 mph (57 km/h) in short distances of approximately 90 meters, and a top speed of 50 mph (80 km/h) for about 20 meters. Lions are very agile and have fast reflexes.

6 - Greyhounds are the fastest dogs, and have primarily been bred for coursing game and racing. It can run 46.0 mph

7 - Jackrabbit's strong hind legs allow it to leap 3 m (9.8 ft) in one bound; some can even reach 6 m (20 ft). Jackrabbits use a combination of leaps and zig-zags to outrun predators. It can run 45.0 mph.

8 - African Wild Dog can sprint at 66 km/h (41 mph) in bursts, and they can maintain speeds of 56–60 km/h (35–37 mph) for up to 4.8 km (3 mi).

9 - Kangaroo's comfortable hopping speed  is about 21–26 km/h (13–16 mph), but speeds of up to 71 km/h (44 mph) can be attained over short distances, while it can sustain a speed of 40 km/h (25 mph) for nearly 2 km (1.2 mi).

10 - The fastest horse speed was achieved by a Quarter horse. It reached 70.76 km/h (43.97 mph).
