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 fully grown.
These armadillos prefer to burrow in very dry soil. They leave their burrows if it is moistened by rainfall. They 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 burrows during the day and feed at night. They are remarkable diggers.
