Sloths are a group of mammals, noted for their slowness of movement, and spend most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America. They are considered to be most closely related to anteaters.

Anteater is a common name for the four extant mammal species commonly known for eating ants and termites. The individual species have other names in English and other languages.

Pangolins, sometimes known as scaly anteaters, are mammals of the order Pholidota, from Ancient Greek meaning clad in scales. The one extant family, the Manidae, has three genera: Manis, Phataginus, and Smutsia. The genus Manis comprises the four species that are found in Asia. The other genus, Phataginus with two species and Smutsia with two species are all found in sub-Saharan Africa.
