They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail. Family: Didelphidae (American opossums) Subfamily: Caluromyinae. Genus: Caluromys. Derby's woolly opossum, Caluromys ...
In addition to the Greater Antillean sloths, some other pilosans are still extant on islands close to the Central and South American mainland. This includes several anteaters and a member of the other extant sloth family, that of the three-toed sloths , restricted to a small island in Panama. [ 10 ]
South America's 20 genera of nonhuman primates compares with 6 in Central America, 15 in Madagascar, 23 in Africa and 19 in Asia. All South American monkeys are believed to be descended from ancestors that rafted over from Africa about 25 million years ago in a single dispersal event. Suborder: Haplorrhini. Infraorder: Simiiformes
The brown-throated three-toed sloth (Bradypus variegatus) is the most common of the extant species of sloth, which inhabits the Neotropical realm [1] [9] in the forests of South and Central America. The pale-throated three-toed sloth (Bradypus tridactylus), which inhabits tropical rainforests in northern South America. It is similar in ...
There are 31 living species: the anteaters, tree sloths, and armadillos. [1] Extinct xenarthrans include the glyptodonts, pampatheres and ground sloths. Xenarthrans originated in South America during the late Paleocene about 60 million years ago. [2]

Ground sloths represent a paraphyletic group, as living tree sloths are thought to have evolved from ground sloth ancestors. The early evolution of ground sloths took place during the late Paleogene and Neogene of South America, while the continent was isolated. At their earliest appearance in the fossil record, they were already distinct at ...
