CATDOLL : CATDOLL: What are the characteristics of a scorpion?

Scorpion

The ideal body length of an adult scorpion is about 55mm, and its appearance is very similar to that of a pipa. The life span of a scorpion is between 5 and 8 years. The body of a scorpion is very clearly segmented, and the entire surface of the body is covered with a hard skin with a high degree of chitin.

It is composed of the cephalothorax and abdomen. The body is yellow-brown, with lighter colors on the ventral surface and appendages, and darker colors on the fifth segment of the posterior abdomen. Scorpions are dioecious and slightly different in appearance. The cephalothorax is composed of six segments and is trapezoidal. The back is covered with a head armor, which is densely covered with granular protrusions. There is a pair of central eyes in the center of the back, and three lateral eyes on each side of the front. There are 6 pairs of appendages. The first pair is a whole limb that helps with feeding, and the second pair is a long and thick crab-like horn whisker that is responsible for predation, touch and defense. The remaining four pairs are walking legs. The mouth is located at the bottom of the front cavity of the abdomen.

The front abdomen is relatively wide and consists of 7 segments. The back abdomen is a long and narrow part that is easy to bend, consisting of 5 body segments and a tail stinger. The first segment has a genital operculum, which covers the genital opening. Female scorpions can give birth to young scorpions from the genital opening, and male scorpions can produce sperm sticks from the genital opening, which intersect with the genital opening of the female scorpion.

The order Scorpio has 9 families and 1,400 species, forming the most primitive group of the entire arachnid order. Scorpions are large arachnids that live in deserts, grasslands, forests, and sometimes even in people's homes. Scorpions are one of the symbols of the constellations in mythology, and have always appeared in front of the world with a frightening and confusing image. Scorpions can be up to 15 cm or longer in length, including their chelae. The chelae are highly developed pedipalps with many sections on their trunks, and the last section ends with a stinger, which is used for self-defense or killing prey. The organ at the end of the stinger is very sensitive and can often be used to detect ground vibrations. At the same time, the tentacles on its pincers can accurately sense the air flow caused by the movement of the prey. Once it finds prey, it extends its pincers forward, holds its abdomen high, and tilts its tail, ready to sting the prey.
