what is The fastest animal on earth?

•  The fastest animal 

The peregrine falcon is the fastest animal on earth, in addition to being the fastest bird, with a speed of more than 386 km/h.  As for the fastest animal in the water, researchers differed in determining it;  Some of them see it as a sailfish, others see it as black marlin, and the speed of both reaches approximately 113 km/h or more.

• peregrine falcon

The peregrine falcon is one of the birds of prey belonging to the falcon family (the scientific name: Falco peregrinus), and it feeds on other birds and bats, and it To chase its victim, it may strike rapidly and deeply. Concerning migration, these birds are constantly on the move, so they are called roving hawks, but some of them settle in the same place permanently, and those migratory ones are predominantly in the icy plains environment in the Arctic, and they move in winter to South America and fly an estimated distance of 24944.83 km per year.

Our large and powerful birds, gray with little to no lighter or brown on the upper side, the peregrine falcon is one of the fastest birds in the world; It can reach speeds of more than 250 comers per hour when searching for prey, and it is one of the most widely distributed birds in the world.

 There are 19 species of peregrine falcon; They vary greatly in size and color, they have a thin gray crown, white or reddish-brown underparts, and the skin of the peregrine falcon's face and legs ranges in color from yellow to orange.

 Females of the peregrine falcon are approximately 20% larger, and the peregrine falcon communicates with each other in ways, emitting a steady, harsh, and raucous sound when interrupted or disturbed.

• Cheetah 

The cheetah has a long, thin physique; an adult leopard's typical length is 77 cm from shoulder to shoulder, 112 to 142 cm from head to buttocks, and weighs around 450 kg. 34 to 64 kg, according to the Smithsonian Institution of America.  The teeth are relatively small in size, which constitutes a weak point for him when fighting larger animals of the same species, such as lions;  In this case, it depends on its speed to escape from it, and it is indicated that the female cheetah tends to be isolated, while the male cheetah lives in groups.

The cheetah is considered the fastest runner among mammals in the world; Its speed reaches 113 km / h, and it accelerates by 72 km / h within two seconds, during which it travels a distance of 59 m, but after a few hundred meters it exhausts its energy to endurance, especially when running at full speed, and it is reported that he can run for half an hour at a speed ranging from 48 and 64 km/h.

 If the speed of the cheetah is compared to the speed of birds, the speed of the homing pigeon is greater, as it is faster than the cheetah; Where it reaches an average speed of 151.8 km/h during its flight over a distance of more than 128.7 km, while the speed of a cheetah is close to the speed of a peregrine falcon and some types of ducks and geese if it is forced to walk at a high speed.

 As for the speed of some mammals, the American antelope comes after the cheetah with its super speed, reaching a speed of 96.6 km / h, and it can maintain this speed constant for a distance of 6.4 km, then the horse, whose speed ranges between 72.4 and 80.5 km / h.
