Pilosa in the context of "Ground sloth"

Anteaters are the four extant mammal species in the suborder Vermilingua (meaning 'worm tongue'), commonly known for eating ants and termites. The individual species have other names in English and other languages. Together with sloths, they are within the order Pilosa. The name "anteater" is also commonly applied to the aardvark, numbat, echidnas, and pangolins, although they are not closely related to them.

Extant species are the giant anteater Myrmecophaga tridactyla, about 1.8 m (5 ft 11 in) long including the tail; the silky anteater Cyclopes didactylus, about 35 cm (14 in) long; the southern tamandua or collared anteater Tamandua tetradactyla, about 1.2 m (3 ft 11 in) long; and the northern tamandua Tamandua mexicana of similar dimensions.

The giant anteater (Myrmecophaga tridactyla) is an insectivorous mammal native to Central and South America. It is the largest of the four living species of anteaters, which are classified with sloths in the order Pilosa. The only extant member of the genus Myrmecophaga, the giant anteater is mostly terrestrial, in contrast to other living anteaters and sloths, which are arboreal or semiarboreal. The species is 182 to 217 cm (72 to 85 in) in length, with weights of 33 to 50 kg (73 to 110 lb) for males and 27 to 47 kg (60 to 104 lb) for females. It is recognizable by its elongated snout, bushy tail, long foreclaws, and distinctively colored fur.

The giant anteater is found in multiple habitats, including grassland and rainforest. It forages in open areas and rests in more forested habitats. It feeds primarily on ants and termites, using its foreclaws to dig them up and its long, sticky tongue to collect them. Though giant anteaters live in overlapping home ranges, they are mostly solitary except during mother-offspring relationships, aggressive interactions between males, and when mating. Mother anteaters carry their offspring on their backs until weaning them.

Sloths are a Neotropical group of xenarthran mammals constituting the suborder Folivora, including the extant arboreal tree sloths and extinct terrestrial ground sloths. Noted for their slowness of movement, tree sloths spend most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America. Sloths are considered to be most closely related to anteaters, together making up the xenarthran order Pilosa.

There are six extant sloth species in two genera – Bradypus (three-toed sloths) and Choloepus (two-toed sloths). Despite this traditional naming, all sloths have three toes on each rear limb – although two-toed sloths have only two digits on each forelimb. The two groups of sloths are from different, distantly related families, and are thought to have evolved their morphology via parallel evolution from terrestrial ancestors. Besides the extant species, many species of ground sloths ranging up to the size of elephants (like Megatherium) inhabited both North and South America during the Pleistocene Epoch. However, they became extinct during the Quaternary extinction event around 12,000 years ago, along with most large animals across the Americas. The extinction correlates in time with the arrival of humans, but climate change has also been suggested to have contributed. Members of an endemic radiation of Caribbean sloths also formerly lived in the Greater Antilles but became extinct after humans settled the archipelago in the mid-Holocene, around 6,000 years ago.
