Pink fairy armadillos (or pichiciegos) are found in the warm sandy plains of Argentina.

These armadillos prefer to burrow in very dry soil. They leave their burrows if it is moistened by rainfall. These animals often burrow near anthills, so that they can be close to their food source. The pink fairy armadillo generally lives by itself. The animals stay in their burrrows during the day and feed at night. They are remarkable diggers.

The pink fairy armadillo is the smallest member of the armadillo family, measuring only about five to six inches in length. It is also the only armadillo in which the dorsal shell is almost separate from the body.

Baby armadillos resemble their parents, but their shells do not completely harden until they are full grown.
