The southern three-banded armadillo (Tolypeutes matacus) is indigenous to central South America, ranging between Argentina, Brazil, Paraguay, and Bolivia. 

Like most armadillos, the southern three-banded is covered in plates of leathery armor that protect it from predators. But what makes this armadillo special is its ability to roll completely into a ball. The neighboring Brazilian three-banded armadillo is the only other armadillo with this adaptation. The adaptation works well in the wild—only jaguars, alligators, and pumas are powerful enough to punch through the protective plates.

Habitat loss is a challenge for many species, including the southern three-banded armadillo. During the 20th century, the rich Rio de la Plata river basin underwent agricultural development; the habitat changed from a flood plain to cultivated fields of crops such as soy and sorghum. Today, the southern three-banded armadillo is classified as a near threatened species.
