It is found only in the deserts and scrublands of central Argentina, mainly in the provinces of Mendoza, San Luis, Buenos Aires, La Pampa and San Juan. It lives mainly in loose sand dunes, along with dry grassland and sandy plains, from sea level up to 1,500 meters. It measures less than 15 centimeters (6 inches) from head to tail, but its weight depends on which source you ask. Animal Diversity Web gives an average of 120 grams (4 ounces), a 2023 study of its skin says about 100 grams, and the AnAge ageing database lists 44.3 grams. Lifespan is just as uncertain. One captive individual lived 4.3 years, but no maximum has been established, and it may be much longer. It is generally called an insectivore, but it will eat plants if the right conditions arise, and the main food anyone has observed it eating is ants. It is active at night or at dawn and dusk, and it has digging claws on its front legs. > **Armor for a Life Underground** This armadillo spends almost its whole life below ground, and it carries a carapace made of bony plates and hardened scales. ## An Armor That Isn't Bolted Down This armadillo's light pink carapace is attached to its body only by a thin membrane running down the middle of its back. It has 24 bands, plus an extra vertical plate at the rear that gives the shell its blunt end. A 2023 study of its skin found that almost all of the carapace is flexible, one of several features that set it apart from other armadillos. Its eyes are small, and its whiskers, or vibrissae, keep the basic armadillo structure but are thinner and shorter, a change researchers think is probably linked to passively monitoring its surroundings. The arrangement of hairs on the armor plates near its rear is modified too, in a way scientists think may help it move through sandy tunnels. ## Predators, Rarity and a Question Mark Its main defense against predators is the carapace covering its back, and its burrows and tunnels give it a refuge. Its greatest predators are domestic cats and dogs. It is so rarely seen that, according to Animal Diversity Web, the local person known for having seen the most had seen only 12 in 45 years. The IUCN lists it as Data Deficient, meaning there is not enough information yet to judge how threatened it is. ## Frequently Asked Questions ### Can a pink fairy armadillo survive in captivity? Not easily: it is extremely difficult to keep in captivity. One published case study kept a male in an artificial enclosure for eight months, and a stable, undisturbed setup with plenty of compact sand and hiding places on the surface was the key to keeping him alive. Any small change to his enclosure or diet triggered a stress response, and he was fed a semi-liquid mix of ground cat food, insectivore diet, mashed banana, vitamins and minerals. *(Source: [Superina 2011]())* ### Is the pink fairy armadillo related to other 'fairy armadillos'? Yes. Scientists recognize two species of fairy armadillo, also called pichiciegos: this one and the Chacoan fairy armadillo (Calyptophractus retusus). This species is restricted to central Argentina, while its cousin lives in the Gran Chaco of Argentina, Paraguay and Bolivia. DNA evidence puts the split between the two species at around 17 million years ago, a date that supports placing them in separate genera. *(Source: [Delsuc et al. 2012]())* ### Does a pink fairy armadillo need to drink water? Nobody knows for sure. The few pink fairy armadillos that have survived for any length of time in captivity have never been seen drinking, which suggests they may get their water from their food. Using metabolic water is an adaptation seen in many desert species. *(Source: [Animal Diversity Web, University of Michigan 2017]())* ## Sources 1. [Chlamyphorus truncatus (pink fairy armadillo).
