The pink fairy armadillo is the smallest species of armadillo in the world at 90–115 mm (3.5–4.5 in) long weighs about 120g. They have small eyes, silky yellowish white fur, and a flexible dorsal shell that only protects his top side. Because we only need protection from things that attack us from above. To its credit, it rolls up nicely into a hard shelled ball. The most unique characteristic is their ability to “swim” through the sand. The fairy armadillo is known for its large front claws that allow it to move through the sand as quick as it does through water.
