What is "rodent"?

Rodent refers to a group of small to medium-sized mammals characterized by their continuously growing incisors. They have sharp front teeth that never stop growing, which they use to gnaw and chew on various objects, including food, wood, and even wires. Rodents are found on all continents except Antarctica and come in a variety of shapes and sizes, from the tiny pygmy jerboa to the larger capybara, which can weigh up to 140 pounds. Some common examples of rodents include mice, rats, squirrels, hamsters, and guinea pigs. They play an essential role in many ecosystems as they serve as prey for predators such as snakes, birds of prey, and cats, and help to disperse seeds by storing and burying them for later use.
