The Andean hairy armadillo (Chaetophractus nationi) is an armadillo located in Bolivia, in the region of the Puna; the departments of Oruro, La Paz, and Cochabamba (Gardner, 1993). Nowark (1991) describes it as distributed in Bolivia and northern Chile. A recent publication of Pacheco (1995) also locates the species in Peru, basically in Puno Region. This species is also thought to be present in northern Argentina. However, this location may actually only contain a population of C. vellerosus.

This armadillo finds shelter in tunnels and burrows that it digs itself using fore-claws. Their territories are about eight acres in size. The Andean Hairy Armadillo's sleep schedule depend on the season and temperature of its habitat. In the summer months they are considered Nocturnality so they do not overheat. They then switch to Diurnality during the winter season to stay warm. The Andean Hairy Armadillo communicates with other armadillos through the use of chemicals, as well as through touch.


Male Andean Hairy Armadillos only pair up with a female during mating season. They are a Polygynandrous species and each adult lives a solitary life. The male armadillo is known to have the longest penises, in proportion to the body size, of any mammal. Males are called lister and females are called zed. Mating season begins in the fall and young are usually born in the summertime with a total of only two offspring. Females are pregnant for only two months though. This two months pregnancy, but births in the summer is because the family Dasypodidae is known for their ability to have Delayed implantationd and all the embryos produced are from a single zygote. Embryos within the mother still produce their own placenta. Armadillo's offspring are referred to as pups and are born helpless. They remain with their mother fully dependent for fifty days and are sexually mature by twelve months.

Threats and Conservation Aid

The Andean Hairy Armadillo has been given a bad reputation of that with its nine-banded cousin Dasypus novemcinctus and thought to carry Leprosy. The main threat to this species is being hunted and having its shell sold for musical instrument making, body parts for medical remedies, and for food. Others, simply are killed because they are seen as a pest in that they cause agriculture destruction with their burrow making. Another threat is the fact that they are losing much of their habitat to road construction, farming, and Deforestation. However, there are a few aids out there to try to help this species of armadillo survive. The Convention on International Trade in Endangered Species of Wild (CITES) has banned all trading of the Andean Hairy Armadillo and the capture of it. Yet, the demand for this armadillo's products still remain and many are killed regardless.
