They are comparable to most other mammals and react in the same manner to proven agonists. Platelet counts are similar between sexes and they seem to remain similar even when in captivity. Little is known about the hemostasis of this species. Even with the added challenge of burrowing, this armadillo maintains similar ratios as nonfossorial species and suggests it has adapted to a burrowing lifestyle as a way to avoid extreme temperatures and predators, rather than any help it could receive from foraging. This, along with its powerful digging claws and high surface-area-to-mass ratio, contributes to this fossorial, or subterranean, lifestyle. It is able to maintain sufficient respiratory movements due to a mechanism that allows it to use air that fills the space between soil particles, without inhaling the particles themselves. This species also has a remarkable respiratory adaptation when the nostrils are completely covered in soil. These protective plates allow the individual a fair measure of protection against its natural predators. ![]() The most recognizable of these are the bony plates that cover the armadillos' heads and backs. villosus, have evolved very interesting and specific traits to help them survive. For now, body size, habitat, and behaviors are the best way to discern the differences. More research is being done to better describe these species and the skeletal differences between them. Not much is known about the cranial morphology of these species, especially bone descriptions. The skulls follow the same patterns as other dasypodids, but females exhibit longer bones in the rostrocaudal plane, which is one of the key characteristics that shows the sexual dimorphism of these species. These species are recognized by the large amount of hair that extends all over their bodies, but especially on their undersides. nationi (the Andean hairy armadillo, which may actually be a population of C. vellerosus (the screaming hairy armadillo), C. ![]() The genus Chaetophractus consists of two or three species, C. The armadillo can use specially evolved membranes in its nose to obtain oxygen from the surrounding soil particles without inhaling any of the soil itself. Powerful front claws are used for both foraging and avoiding predators. The tail measures 9 to 17 cm (3.5 to 6.7 in) long. ![]() The average individual grows from 26 to 34 cm (10 to 13 in) in body length, 22–40 cm (8.7–15.7 in) in extreme cases, and weighs 2 kg (4.4 lb), with a range of 1–3 kg (2.2–6.6 lb) by the time it reaches maturity. Long, coarse hairs also project from the bony plates, making this armadillo much hairier than other related species. The underside of this armadillo is densely covered in hair and this trait is how it got its common name. Along its back, flexible bands that encircle the torso allow flexibility in this otherwise stiff armor. The armadillo's head and body are covered by protective bony plates, with its head plate being the most prominent. This species of armadillo is a preferred research animal due to its adaptability to laboratory settings, and relative hardiness in situations of stress.Ĭhaetophractus villosus or the big hairy armadillo is the most abundant species of armadillo in Argentina. Currently, no protective practices are in place for this armadillo, but it does live in many protected areas. Though this animal is routinely harvested for its meat and its shell, or simply killed by farmers, it has shown resiliency, and populations seem to be handling this exploitation well. They reach sexual maturity at around 9 months and have been known to live over 30 years in captivity. It makes both temporary and long-term burrows, depending on its food source.Īrmadillos are protected from predators by a series of thin, bony plates along the head and back. It is an accomplished digger and spends most of its time below ground. It lives from sea level to altitudes of up to 1,300 meters across the southern portion of South America, and can be found in grasslands, forests, and savannahs, and has even started claiming agricultural areas as its home. The big hairy armadillo or large hairy armadillo ( Chaetophractus villosus ) is one of the largest and most numerous armadillos in South America.
