 | | Currently the group includes armadillos, two-toed sloths, three-toed sloths, and anteaters, placed in four families: Dasypodidae (armadillos), Myrmecophagidae (anteaters), Bradypodidae (tree-toed sloths), and Megalonychidae (two-toed Sloths). |
 | | Sloths are the most diverse Xenarthran group with about 100 known genera, but most of them became extinct around 10,000 years ago, such that only five species continue to exist in Central and South America. |
 | | Sloths are traditionally arranged into two extinct, Megatheriidae and Mylodontidae, and two extant families, Megalonychidae (with genus Choloepus) and Bradypodidae (with genus Bradypus). |
