The Pink Fairy Armadillo (Chlamyphorus truncatus) or Pichiciego is the smallest species of armadillo (mammals of the family Dasypodidae, mostly known for having a bony armour shell). It is approximately 90-115 mm long excluding the tail, and is pale rose or pink in colour. It is found in central Argentina where it inhabits dry grasslands and sandy plains with thorn bushes and cacti. It has the ability to bury itself completely in a matter of seconds if frightened.
The Pink Fairy Armadillo burrows small holes near ant colonies in dry dirt. It feeds mainly on ants and ant larvae near its burrow. Occasionally it feeds on worms, snails, insects and larvae, or various plant and root material.
In 1996 the species was classed as endangered by the IUCN. However, this was downgraded to near threatened in 2006, and in 2008 changed to data deficient. Although concern exists over habitat destruction, particularly due to cattle farming, the actual effects are poorly understood.
