Rodents are mammals characterised by higher and reduce pairs of ever-increasing rootless incisor enamel. Rodents are the largest team of mammals, constituting Nearly fifty percent of the class Mammalia’s around four,660 species. This is a list of picked rodents, arranged alphabetically by suborder and family. (

Although some rodents have a standing as agricultural pests or vectors of illness, rodents generally provide sizeable ecological, dietary, aesthetic, and scientific values. In many habitats, They're extremely ample, and therefore are very important in food webs and in dispersal of plant seeds.
Rodent incisors are rootless, increasing repeatedly. Their anterior and lateral surfaces are lined with enamel, but their posterior area will not be. All through gnawing, as being the incisors grind towards each other, they don absent the softer dentine, leaving the enamel edge because the blade of a chisel.
