List of pilosans

Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the pilosan's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".

The order Pilosa consists of twelve extant species in two suborders: Folivora, the sloths, and Vermilingua, the anteaters. Folivora contains two families: Bradypodidae, containing four species in one genus; and Choloepodidae, containing two species in one genus. Vermilingua also contains two families: Cyclopedidae, containing a single species, and Myrmecophagidae, containing three species in two genera. Many of these species are further subdivided into subspecies. This does not include hybrid species or extinct prehistoric species.

The following classification is based on the taxonomy described by the reference work 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.[4]
