What animal is poor little eyes?

Rats, also known as rats or mice, namely Muroidea, belong to the rodent superfamily, including hamsters, gerbils, rats and other related animals.

They are widely distributed in all continents except Antarctica. Because it is difficult to determine the relationship between taxa, there are also documents that classify all rodents as rodents. According to the molecular systematics, there are about 280 genera and at least 1300 species.

They are one of the few animal groups that keep close contact with human beings and thrive. These animals can be found in almost all countries in the world, and some of them are important biological model organisms, which are of great help to human experiments and research. In addition, some mice are also pet mice.

There is an idiom called "the mouse is the name of the tiger". According to the story, Chu people call tigers old worms, Suzhou people call mice old worms, and some people are officials in Changzhou. He went to Taicang on business, and it was noisy outside the post station all night. He asked the doorman what it was. The doorman said it was an old bug and ran away in fear.

But the doorman said there was no need to panic. It was just a mouse. Later, it refers to people who pretend to be celebrities to scare the world. So mice are also called old bugs. There are not only many kinds of mice, but also an amazing number. It is estimated that the total number of rats in the world exceeds the population by several times. Besides Rattus norvegicus, Rattus flavipectus, Rattus norvegicus and Rattus norvegicus, there are nest rats, voles, gerbils, hamsters, muskrats and zokor.
