Pholidota is an order of placental mammals in the Pholidotamorpha clade. A member of this order is called a pholidotan or a pangolin. They are distributed throughout Africa, the Indian subcontinent and southeast Asia, and are usually found in habitats such as savannas, forests, grasslands and shrublands. Pholidotans range in size from the giant pangolin, at 30 kg (66 lb) and 68 cm (27 in) in length, to the tree pangolin, at only 2.3 kg (5.1 lb) and 34 cm (13 in) in length. They have large, hardened, keratin scales which cover the entirety of the body surface, and long claws which they use for digging or climbing trees. 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.[1][2]

The eight extant species of Pholidota are split into three genera within three subfamilies: Maninae (Asian pangolin), Phatagininae (African tree pangolin) and Smutsiinae (African ground pangolin). Manidae is the only extant family within the Pholidota order, as the other three families—Eurotamandua, Patriomanidae, and Eomanis—have gone entirely extinct. As such, around six extinct species have been described, though the exact categorization and number is not fixed due to ongoing research.[1]

Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided where possible; if unavailable, a description of the species will instead be provided. All extinct species and subspecies listed alongside extant species went extinct in prehistoric times, and are indicated by dagger symbol "†". Population figures are rounded to the nearest hundred.

Classification

[edit]

The Pholidota order is composed of eight extant species belonging to three genera in three subfamilies. This does not include extinct species or hybrid animals.

[edit]

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 the IUCN Red List.[1][7]
