Which is the animal that is overbearing

often look at the crab roe with a cold eye to see how long you are rampant", linking crabs with rampant is to say that our common crabs are indeed rampant. Sideways movement is a characteristic of crabs, which is determined by the special body structure of crabs. There are also crabs that are not rampant, of course, most people have never seen them, even the rampant crabs are not actually in a straight direction, as long as you look closely, you can find that its trajectory is pointing to the side and forward.

Probably the most impressive thing about crabs is that they crawl sideways. As a result, it also has the nickname "Rampage General". "Rampant General" has some meaning of being empty-sighted, so people often use crabs as a symbol of rampant domineering.

So, why do crabs run amok? This starts with the body structure of the crab.

The back of the crab has a hard shell that encloses the entire body. From the back, only a pair of eyes in front, two pairs of antennae, and five pairs of legs on both sides can be seen; Viewed from the ventral surface, behind the eyes and antennae is the mouth of the crab, which has three pairs of flaky jaws on the outside, and below it is the umbilicus of the crab. The head and thorax of the crab are completely together, and only the presence of the eyes, antennae, and mouth mentioned above makes one guess that their position should be the position of the head.

However, according to scientists' research, the three pairs of jaws on the outside of the mouth belong to the chest, so the head and chest of the crab are indistinguishable from each other in appearance. Because the shell on the back of the crab covers the cephalothorax, it is called the cephalothorax, and the shell on the ventral surface of the cephalothorax is called the thoracic carapace. The crab's ten legs grow on both sides of the abdominal armor of the chest, and the first pair is like pincers, called chelicerae, which can be used for feeding and fighting; The last four pairs are used for walking, called the foot, and each of them is composed of seven segments, which are called knuckles, anterior joints, wrist joints, long joints, base joints, base joints, and base segments from the end.

The joints are connected by different joints to form a system of levers, and most crabs have a cephalothorax that is wider than the length, and the feet are extended on both sides of the body. In this way, when the crab crawls, it can only bend on one side of the foot, grasp the ground with the fingertips, and stretch the other foot outward as much as possible, and when the fingertips reach the ground in the distance, it begins to contract; The bent side of the foot is straightened at the same time, pushing the body to the opposite side, that is, taking a step in the direction of the side. However, due to the different lengths of these five pairs of feet, the real direction of movement is to point sideways forward.

Not all crabs are rampant. The crab's rampage is largely influenced by the shape of the receptor. The long-wristed monk crab that lives on the beach has a narrow body and four pairs of feet can stretch forward, so their movement is often forward, rather than sideways.

In addition, spider crabs that live in seaweed bushes have slender feet and a body that grows longer than wide, and they can climb vertically on the seaweed. Therefore, the word "sideways" cannot simply be used to describe the movement of crabs. Crab.

The three most temperamental animals in the world are "rampant" in the animal kingdom all day long, don't mess with them.

Animals that are rampant and domineering are tigers and river crabs.

1. Tiger. Tigers often move alone, and only live together during the breeding season. Each tiger has its own territory.

When males and females patrol their territory, they raise their tails to spray strong-smelling secretions and urine on tree trunks or bushes to define their sphere of influence.

2. River crabs. The transverse movement of the river crab is determined by the structure of the knee-like joints and oblique joints of its four pairs of feet. In terms of its domineering, in addition to its morphological structure, it has a strong chelicerae for predation, fragmentation and resistance to predators, which is mainly determined by the living habits of river crabs. River crabs are not only very gluttonous, but also envious and aggressive.

Fighting each other for delicious food; The male crab fights with all his might to compete for a female; Cannibalism when there is a lack of food.

The answer to this riddle is crabs. Crabs have four pairs of legs, "big brother", "second brother", "third brother", and "fourth brother", and can move freely on land. And when it is in the water, it is as free as a bird that "calls in the sky", and can soar in the water.

It also has a very special habit, that is, it likes to burrow into the mud and sand on the beach, as if crying.

It can be said that the crab is a very interesting animal. They belong to the crustacean family, with a hard shell but a very soft interior, and a very unique body structure. They also have a pair of large, asymmetrical pincers that can be used to catch prey, as well as for self-protection.

In addition, crabs have very good eyesight, and although they may not be able to see colors clearly, they can see very small objects and even insects.

Crabs play a very important role in nature. They can help maintain the balance of the ecosystems of land-related oceans and freshwater lakes and rivers, they can clean waste from riverbeds and ocean bottoms, and they can also be an important link in the food chain. In addition, there are many legends and meanings of crabs, such as in Southeast Asian countries, crabs symbolize "protection", and people will give crabs as gifts to newlyweds to pray for their happiness.

In short, crabs are a very interesting and mysterious animal. Many people only know that they can be eaten, but in fact, their living habits and the role they play in the early stage of the ecosystem are worthy of our in-depth understanding and exploration. <>

The tiger is very ferocious, it has sharp tiger teeth, muscular limbs, kicking the ground and pure speed and explosiveness, so the tiger is called the king of beasts, it feeds on catching hidden animals, small to squirrels, rabbits, large to sheep, rhinoceros, in the animal world tigers can almost do rampage, rampant and domineering, is a king!

Crabs cross the street and run rampant. It is a metaphor for people who are arrogant and unreasonable, and very domineering.

The crab has a hard shell on the back of its body and five pairs of legs on either side of the ventral carapace of the thorax. The first pair of macro-fissures resembles pliers, called chelicerae. It is particularly powerful, and is used to conceal stupidity and fight.

The last four pairs of feet are used for walking, and are called foot feet. The foot is composed of seven segments, which are called the knuckles, anterior segments, carpal segments, long segments, base segments, basal segments, and subbase segments from the ends. The necklace of joints with different axial surfaces between the joints forms a system of levers.

The sections of the foot can only be moved up and down, but not back and forth. Therefore, there is a crab crossing the street, rampant and domineering afterwords.
