Rodents are animals that gnaw with two continuously growing incisors. Forty percent of mammal species are rodents, and they inhabit every continent except Antarctica. This list contains circa 2,700 species in 518 genera in the order Rodentia. [1]
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .

A number of species, especially the gerbils, are adapted to desert conditions and can survive for a long time with minimal water. They consume a wide range of foods depending on the species, with the aid of powerful jaw muscles and gnawing incisors that grow throughout life. The dental formula of murids is 1.0.0.1-3 1.0.0.1-3.
Most species are nocturnal and feed primarily on ants and termites, though other insects may also be taken. Despite only a few pholidotans having population estimates, all eight species are classified as threatened by the IUCN Red List, with three being classified as critically endangered, largely due to intensive poaching of their keratin scales.
