Southern three-banded armadillos are the only species of armadillos that can roll into a complete ball to defend themselves. They have three bands that cover the back of the animal, its tail and head together. This allows it to protect its underbelly, limbs, eyes, nose and ears from predators. The shell covering its body is armored and the outer layer is made out of keratin. Southern three-banded armadillos have three middle toes on the back feet. They are grown together and have a thick claw. The forefeet toes are seperated and have 4 claws. These armadillos are typically a yellow or brownish color.

Distribution

Southern three-banded armadillos occur in South America. They are found in parts of northern Argentina, southwestern Brazil, Paraguay and Bolivia. These animals inhabit grasslands or marshes near dry forests or savannah areas.

Habits and Lifestyle

Southern three-banded armadillos are generally solitary creatures. Although they do occasionally group together during cold weather. Unlike most armadillos, they are not fossorial, they do not dig their own burrows. These animals like to use abandoned anteater burrows, or they make their dens under dense vegetation. When foraging these Southern armadillos use their strong legs and large claws. They dig through insect colonies or under bark to get to their food. They have a long, sticky, straw-like pink tongue that helps them then to gather up and eat those insects. When threatened Southern three-banded armadillos roll into a ball. This way they protect themselves.
