List of rodents

Rodentia is an order of placental mammals. Members of this order are called rodents. The order comprises 2,360 extant species, which are grouped into 511 genera. The largest order of mammals, rodents comprise about 40% of all mammal species worldwide. They are native to all major land masses except for Antarctica, and can be found worldwide. They live in a variety of habitats, particularly forests, grasslands, and shrublands, but also savannas, wetlands, deserts, and rocky areas. Most rodents are small animals with robust bodies, short limbs, and long tails. They range in length from the African pygmy mouse, at 4 cm (2 in) plus a 2 cm (1 in) tail, to the capybara, at 134 cm (53 in) plus a 2 cm (1 in) tail.

Rodentia is divided into five suborders: Anomaluromorpha, Castorimorpha, Hystricomorpha, Myomorpha, and Sciuromorpha. The suborders are further subdivided into clades and families. Anomaluromorpha contains two families, the scaly-tailed squirrels and the springhares. Castorimorpha contains three families and includes beavers, gophers, kangaroo rats, and pocket mice. Hystricomorpha contains 18 families and includes mole-rats, porcupines, cavies, hutias, tuco-tucos, and Neotropical spiny rats. Myomorpha contains nine families and includes jerboas, hamsters, voles, and a wide variety of rats and mice. Sciuromorpha contains three families and includes squirrels, chipmunks, and dormice.^[1][2] The exact organization of the species is not fixed, with many recent proposals made based on molecular phylogenetic analysis. In addition to the extant rodents, 38 species have been driven extinct since 1500 CE.

The author citation for the species or genus is given after the scientific name; parentheses around the author citation indicate that this was not the original taxonomic placement. Range maps are provided wherever possible; if a range map is not available, a description of the collective range of species in that genera is provided. Ranges are based on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species unless otherwise noted. All extinct genera or species listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".

The order Rodentia consists of 2,360 extant species belonging to 511 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 511 genera can be grouped into 35 families; these families are divided between 5 named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named subfamilies. An additional 38 species have been driven extinct since 1500 CE: 8 in the family Capromyidae, 6 in Echimyidae, 11 in Cricetidae, and 13 in Muridae.

Members of the Capromyidae family are called capromyids or hutias. They are omnivores and eat leaves, fruit, bark, and small animals.^[62] Capromyidae comprises ten extant species in five genera, grouped into two subfamilies: Capromyinae, containing nine species, and Plagiodontinae, containing a single species. Additionally, two species in Capromyinae, three species in Plagiodontinae, the sole species in the subfamily Hexolobodontinae, and the two species in the subfamily Isolobodontinae were driven extinct after 1500 due to the European colonization of the Americas and introduction of non-native rats, with some species surviving until the 1900s.^[63]

They primarily eat a wide variety of vegetation, though some species also eat insects.^[74] Echimyidae comprises 88 extant species in 23 genera, split into three subfamilies: Caterodontinae, containing a single species; Echimyinae, containing 75 species, and Euryzygomatomyinae, containing 12 species.

Members of the Sciuridae family are called sciurids and include squirrels, chipmunks, and marmots. They primarily feed on fruit, seeds, and nuts, though many species also eat insects, fungi, bark, eggs, and small vertebrates.^[532] Sciuridae comprises 284 extant species in 60 genera, divided into 5 subfamilies: Callosciurinae, containing 67 species of Asian squirrels; Ratufinae, containing 4 species of giant squirrels; Sciurillinae, containing a single species of pygmy squirrel; Sciurinae, containing 84 species of flying squirrel and tree squirrels; and Xerinae, containing 128 species of marmots, chipmunks, prairie dogs, and ground squirrels.
