Rodentia is a large order of mammals that includes mice, rats, squirrels, and porcupines. They are characterized by their long, sharp incisors, which are used for gnawing and burrowing. Rodents are found in a variety of habitats, from deserts to forests, and can live up to three years in the wild. The current population of rodents is estimated to be around 4,660 species. They range in size from the tiny African pygmy mouse, which is only 2.5 cm long, to the capybara, which can grow up to 1.3 m long. Rodents are typically brown or gray in color and have short fur.
Name Origin: The name Rodentia is derived from the Latin word rodere, which means "to gnaw". This is in reference to the gnawing behavior of rodents, which is a defining characteristic of the group.
