The fastest animal in the world is "Cao Cao", because "speak of Cao Cao, and Cao Cao will arrive". Just kidding. When it comes to the fastest animal in the world, many people think of the cheetah for the first time. Cheetah is known as the fastest running animal on the land. Its fastest speed is as high as 110 kilometers per hour, and it takes only more than 3 seconds to accelerate from 0-100 kilometers per hour, killing many man-made super runs. So, is the cheetah really the fastest animal in the world? The answer is No. Let's discuss this problem briefly.
(cheetah that is fast enough to blur)
The ultimate speed of the cheetah has always been that the cheetah is the fastest animal. This concept is deeply rooted in the hearts of the people. Cheetahs belong to the cat family. In general, the running speed of large cats is normal in the animal kingdom, mostly about 50-60 kilometers per hour. For cats, this speed can not only catch up with their prey, but also avoid excessive physical exertion when chasing their prey.
However, the cheetah is an exception. In order to pursue the ultimate speed, it has not only evolved a very "slim" body, but also degraded its bite force and teeth to the point that it can not directly lock the throat of its prey. As a result, the cheetah is only distributed in Africa, and its prey is relatively simple, that is, the antelope, which is also fast and relatively small. In addition, the extreme speed of the cheetah can only last for about 10 seconds. If the cheetah does not catch up with its prey within this time, it will enter a weak period due to excessive energy consumption due to excessive speed. On the African steppe surrounded by fierce animals, the weak period obviously puts itself in a dangerous situation.
Therefore, although the cheetah's speed is fast, it is the single extreme evolution that makes the cheetah's niche very awkward. It can't even choose an adult spotted hyena, let alone large cats such as leopards and lions.
Cheetahs are not the fastest running animals. Since they are running, they can only run on land. Other animals swimming in the water and flying in the sky can not be regarded as running. Even so, the cheetah is still not the fastest. Among all the animals on the land, the fastest running insect is the tiger beetle.
Tiger beetle is a fierce carnivorous insect. It belongs to the class Insecta Coleoptera tiger beetle family. There are more than 2000 kinds of tiger beetles, which are widely distributed all over the world. From the appearance, the tiger beetle has a slender body, slender limbs (3 pairs of feet), and the upper part of the abdomen is completely covered by sheath wings, and the surface is shining with colorful metallic luster.
The average body length of the adult tiger beetle is about 20mm. Its main food is the adults, larvae and eggs of other small insects. The long and powerful jaws on the head are their sharp tools for hunting.
Seeing this, many friends will ask why the tiger beetle is the fastest running animal because its size is the same as that of its fingernail?
The answer is that the tiger beetle can jump 170 times its body length, that is, 3400 mm, by leaping forward in place. The body length of the cheetah is about 1.5 meters, which is 75 times that of the tiger beetle. According to this ratio, if the tiger beetle is as big as the cheetah, it can jump 255000 mm, or 255 meters. This speed translates into a speed of more than 900 kilometers per hour, which is beyond the reach of even the cheetah.
However, the tiger beetle has weaknesses in its strong jumping ability. When it hunts insects, it usually jumps over its head. Moreover, at such a high speed, the tiger beetle almost loses its eyesight because it can not process so much information in such a short time. This is why everything has its advantages and disadvantages.
Therefore, the fastest animal running on land is not a leopard, but a tiger beetle.
In fact, on land, the cheetah is not the fastest animal. Even in nature, its speed is not very fast. This is because many animals flying in the sky and swimming in the water have speeds beyond the reach of the cheetah.
The first is flying in the sky. For a long time, the brown rain swallow was regarded as the fastest bird, with an average speed of 150 kilometers per hour and a maximum speed of 350 kilometers per hour. However, the extreme speed of the brown swift is very rare. It usually erupts only when it avoids natural enemies. Its normal flight speed is mostly about 110 kilometers per hour. However, there is a kind of bird, which often bursts at a speed of 355 kilometers per hour. It is a peregrine falcon. Peregrine falcon is a Falconidae of Falconiformes, and also the fastest flying bird in the world. As a carnivorous bird, peregrine falcon is not big, with an average body length of about 45 cm, but its prey can be wild ducks larger than itself. When hunting, peregrine falcons usually dive. When diving, the peregrine falcon's speed is extreme. Because of this, even if the wild duck is attacked, it can't react, or even find out who the "murderer" is.
Therefore, the swift is only the fastest bird in long-distance flight, and the fastest bird is actually a peregrine falcon.

The second is water. Fish must be the fastest swimmer in the water. However, in the ocean, there are not only one kind of fastest fish, but two kinds. They are swordfish and swordfish. Swordfish and swordfish have similar appearance. They have a sword like mouth and nose, and both have a back sail like a flag. Their bodies are beautiful and streamlined.
However, it is relatively simple to distinguish the two kinds of fish. Only their dorsal fin is quite different. The dorsal fin of swordfish is smaller, accounting for only about one tenth of the length of the back. The dorsal fin of swordfish is at least twice as large as that of swordfish. It almost covers the whole dorsal ridge of swordfish, and the dorsal fin of swordfish is more like a flag.
Because of their similar appearance and body structure, swordfish and swordfish are very similar in speed. As the fastest swimming fish in the water, their maximum speed can reach 150 kilometers per hour. It is with such a fast speed that its hard and spear shaped mouth and nose play the most lethal (penetrating injury).

To sum up, from the perspective of the fastest animals in the above living spaces, the relative speed of tiger beetles is the fastest, followed by peregrine falcon, brown swift, sailfish and swordfish, and finally the cheetah known as the "king of speed".
