The pink armadillo spends most of its time underground. It has long front claws that allow it to move the sand in its path, very much like it is swimming, which is why it has been called a sand swimmer.
The pink armadillo is shaped somewhat like a torpedo and the shielded head protects it from the dirt and sand as it makes its progress under the earth. When it is inside its burrow, it also has the ability to close the entrance by using the armor plates on its body as a cork.
In addition to its small size, one can easily distinguish the pink fairy armadillo from other species of this group of animals by its dorsal shell. It is the only armadillo that has a dorsal shell that is completely separated from its body. The shell covers the head but does not extend to the rear of the body.
