List of mammals

Mammalia is a class of vertebrate animals. Members of this class are called mammals. The order comprises 5,909 extant species, which are grouped into 163 families, themselves grouped into 27 orders in 3 major divisions. These orders can contain between one and thousands of species, grouped into genera and then into families. Mammals are characterized by the presence of mammary glands which in females produce milk for feeding their young, a neocortex region of the brain, and fur or hair.^[1][2][3] Mammals are native to all major land masses and the oceans, and can be found worldwide. They live in every habitat on Earth. The basic mammalian body type is quadrupedal, with most mammals using four limbs for terrestrial locomotion; but in some, the limbs are adapted for life at sea, in the air, in trees or underground. They range in length from Kitti's hog-nosed bat, at 2 cm (1 in) with no tail, to the blue whale, at 32.6 m (107 ft) long, including tail.

The three major divisions of mammals are the infraclass Marsupialia, containing the marsupial animals wherein the young are carried in a pouch; the infraclass Placentalia, for which the fetus is carried in the uterus, and the order Monotremata, containing egg-laying species.^[4] Marsupialia contains 334 species, Monotremata contains 5, and Placentalia contains the vast majority of extant mammals at 5,570 species. The majority of mammals, in terms of number of species, are in the two largest orders: Rodentia, or rodents, with 2,360 species, and Chiroptera, or bats, with 1,318.^[5][6] The exact organization of the species is not fixed, with many recent proposals made based on molecular phylogenetic analysis. In addition to the extant mammals, 70 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 class Mammalia consists of 5,909 extant species grouped into 1,295 genera belonging to 163 families. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 163 families can be grouped into 27 orders; these orders are divided into 3 major groupings: Marsupialia, an infraclass containing 7 orders of mammals which give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a time; Placentalia, an infraclass containing 19 orders of mammals that have fetuses that are carried in the uterus, and Monotremata, an order of egg-laying mammals.^[4] Within these groupings, the orders are organized into named clades, and some of these orders are subdivided into named suborders. An additional 70 species have been driven extinct since 1500 CE: 13 in Marsupialia and 57 in Placentalia.

The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis, as supported by both the IUCN and the American Society of Mammalogists.^[5][6]

Marsupialia is one of the three main divisions of mammals, and contains 334 extant species. It is distinguished from the other two groups in that marsupials give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time.^[4] It is divided into two groupings: the superorder Australidelphia and Ameridelphia, which was previously considered a superorder but is now regarded as a paraphyletic group. Ameridelphia contains 99 extant species in 2 orders, each containing a single family: Didelphimorphia, or the opossums, and Paucituberculata, or the shrew opossums. Australidelphia contains 235 extant species in 18 families, grouped into 5 orders: Dasyuromorphia, or the Australian carnivorous marsupials; Diprotodontia, or the kangaroos and possums; Microbiotheria, or the monito del montes; and Notoryctemorphia, or the marsupial moles; and Peramelemorphia, or the bandicoots and bilbies. One additional species in Ameridelphia and twelve in Australidelphia were driven extinct in modern times.

Members of the Didelphimorphia order are called didelphimorphs or opossums. They are found in North and South America, Australia, and southeastern Asia and are omnivorous, eating insects, small vertebrates, and vegetation. Didelphimorphia comprises a single family of 92 extant species in 18 genera. One additional species was driven extinct in modern times.

Xenarthra contains 31 species in 6 families, grouped into 2 orders: Cingulata, or armadillos, and Pilosa, the sloths and anteaters. One additional species in Afrotheria, 38 in Euarchontoglires, and 18 in Laurasiatheria were driven extinct in modern times.

They are found in Sub-Saharan Africa and eat invertebrates, fish, amphibians, lizards, and vegetation. Afrosoricida comprises three families of 55 extant species in 20 genera.

Members of the Rodentia order are called rodents. They are found worldwide, and eat a wide variety of plant material and invertebrates, with some species eating small vertebrates or carrion. Rodentia comprises 35 families of 2,360 extant species—about 40% of all mammal species—in 511 genera. These families are grouped into five suborders: Anomaluromorpha, containing the scaly-tailed squirrels and springhares; Castorimorpha, containing breavers, gophers, and kangaroo rats; Hystricomorpha, containing mole-rats, cavies, tuco-tucos, agoutis, and New World spiny rats and porcupines; Myomorpha, containing a wide variety of mice and rats; and Sciuromorpha, containing dormice and squirrels. Additionally, 38 species have been driven to extinction in modern times.

Members of the Artiodactyla order are called artiodactyls or even-toed ungulates, and include deer, cattle, pigs, camels, whales, and dolphins. They are found worldwide on land and in oceans, and eat a wide variety of plant material, fish, and other marine animals. Artiodactyla comprises 24 families of 349 extant species in 133 genera. These families are grouped into four suborders: Ruminantia, containing deer, cattle, goats, a giraffes; Suina, containing pigs and peccaries; Tylopoda, containing camels and llamas; and Whippomorpha, containing whales, dolphins, and hippopotomuses. Three additional species have been driven to extinction in modern times.

Members of the Carnivora order are called carnivorans, and include dogs, bears, raccoons, weasels, seals, cats, hyenas, and mongooses. They are found worldwide on land an in oceans, and are omnivorous, with some species predominately eating plant material or aquatic animals.

Members of the Chiroptera order are called chiropterans or bats. They are found worldwide, and predominately eat insects, with some species also eating fruit or fish. Chiroptera comprises 21 families of 1,318 extant species—about 20% of all mammal species—in 226 genera. These families are grouped into two suborders: Yangochiroptera, containing sheath-tailed, leaf-nosed, free-tailed, and vesper bats, and Yinpterochiroptera, containing Old World leaf-nosed, fruit, and horseshoe bats. Nine additional species have been driven to extinction in modern times.

Monotremata is the smallest of the three main divisions of mammals, containing only five extant species. It is distinguished from other mammals in that the monotremes are egg-laying rather than bearing live young, but, like all mammals, the female monotremes nurse their young with milk.^[4] Unlike the other two divisions, it is considered an order rather than an infraclass, and in turn contains two families of extant species grouped together in the superfamily Ornithorhynchoidea: Ornithorhynchidae, containing only the platypus, and Tachyglossidae, containing four species of echidna in two genera. Monotremes are found in Australia and New Guinea and are carnivorous, eating insects, worms, shrimp, tadpoles, and small fish.
