Cingulata is an order of armored placental mammals. Members of this order are called cingulates, or colloquially, armadillos. They are primarily found in South America, though the northern naked-tailed armadillo is found mainly in Central America and the nine-banded armadillo has a range extending into North America. They are generally found in forests, but also savannas, shrublands, and grasslands. They all follow a similar body plan, and range in size from the pink fairy armadillo, at 11 cm (4 in) plus a 2 cm (1 in) tail, to the giant armadillo, at 100 cm (39 in) plus a 50 cm (20 in) tail. No population estimates have been made for any cingulate species, though the giant armadillo and the Brazilian three-banded armadillo are categorized as vulnerable species.
