Rodents are a type of mammal. Their front teeth are very special and have the property of constant growth and wear. They can be used for various functions such as gnawing, chipping wood, and opening shells. Therefore, these animals are called "rodents".
Rodents' front teeth grow quickly, but wear out with constant use, so they keep chewing on objects to keep the teeth at the right length. With the exception of the front teeth, rodent teeth are generally flat and adapted for chewing hard food. Their usual diet is mainly plants, but some species will eat insects or other small animals when necessary.
Rodents include many species, such as squirrels, mice, hamsters, beavers, gerbils, etc. They are widely distributed in various regions around the world, and people can better understand the laws of nature by observing their living habits and anatomical structures.
