Armadillos are New World placental mammals in the order Cingulata. The Chlamyphoridae and Dasypodidae are the only surviving families in the order, which is part of the superorder Xenarthra, along with the anteaters and sloths. Nine extinct genera and 21 extant species of armadillo have been described, some of which are distinguished by the number of bands on their armor. All species are native to the Americas, where they inhabit a variety of different environments.
The pink fairy armadillo is the smallest species of armadillo, first described by Richard Harlan in 1825. This solitary, desert-adapted animal is endemic to central Argentina and can be found inhabiting sandy plains, dunes, and scrubby grasslands.
The giant armadillo, colloquially tatu-canastra, tatou, ocarro or tatú carreta, is the largest living species of armadillo. It lives in South America, ranging throughout as far south as northern Argentina. This species is considered vulnerable to extinction.
The Pampas fox, also known as grey pampean fox, Pampas zorro, Azara's fox, or Azara's zorro, is a medium-sized zorro, or "false" fox, native to the South American Pampas. Azara in some of its alternative common names is a reference to Spanish naturalist Félix de Azara.
The six-banded armadillo, also known as the yellow armadillo, is an armadillo found in South America. The sole extant member of its genus, it was first described by Swedish zoologist Carl Linnaeus in 1758. The six-banded armadillo is typically between 40 and 50 centimeters in head-and-body length, and weighs 3.2 to 6.5 kilograms. The carapace is pale yellow to reddish brown, marked by scales of equal length, and scantily covered by buff to white bristle-like hairs. The forefeet have five distinct toes, each with moderately developed claws.
The nine-banded armadillo, also known as the nine-banded long-nosed armadillo or common long-nosed armadillo, is a mammal found in North, Central, and South America, making it the most widespread of the armadillos. Its ancestors originated in South America, and remained there until the formation of the Isthmus of Panama allowed them to enter North America as part of the Great American Interchange. The nine-banded armadillo is a solitary, mainly nocturnal animal, found in many kinds of habitats, from mature and secondary rainforests to grassland and dry scrub. It is an insectivore, feeding chiefly on ants, termites, and other small invertebrates. The armadillo can jump 91–120 cm (3–4 ft) straight in the air if sufficiently frightened, making it a particular danger on roads. It is the state mammal of Texas.
The southern naked-tailed armadillo is a species of small armadillo from South America.
The southern long-nosed armadillo is a species of armadillo native to South America.
The southern three-banded armadillo, also known as La Plata three-banded armadillo or Azara's domed armadillo, is an armadillo species from South America. It is found in parts of northern Argentina, southwestern Brazil, Paraguay and Bolivia, at elevations from sea level to 770 m (2,530 ft).
The Andean hairy armadillo is an armadillo found mainly in Bolivia, in the region of the Puna; the departments of Oruro, La Paz, and Cochabamba. Nowark (1991) describes it as distributed in Bolivia and northern Chile. A recent publication of Pacheco (1995) also locates the species in the Puno Region of Peru. This species is also thought to be present in northern Argentina. However, this location may actually only contain a population of C. vellerosus.
The Mozambique rain frog, also known as the flat-faced frog, is a species of frog in the family Brevicipitidae. It is found in Botswana, Democratic Republic of the Congo, Eswatini, Malawi, Mozambique, South Africa, Tanzania, Zambia, Zimbabwe, and possibly Lesotho. Its natural habitats are dry savanna, moist savanna, temperate shrubland, subtropical or tropical dry shrubland, temperate grassland, subtropical or tropical dry lowland grassland, subtropical or tropical high-altitude grassland, arable land, pasture land and rural gardens.
The Chacoan naked-tailed armadillo is a species of South American armadillo.
The screaming hairy armadillo is a species of armadillo also known as the small screaming armadillo, crying armadillo or the small hairy armadillo. It is a burrowing armadillo found in the central and southern parts of South America. The adjective "screaming" derives from its habit of squealing when handled.
The bighairy armadillo is one of the largest and most numerous armadillos in South America. 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. It is an accomplished digger and spends most of its time below ground. It makes both temporary and long-term burrows, depending on its food source.
The hairy long-nosed armadillo or woolly armadillo is a species of armadillo in the family Dasypodidae. It is endemic to Peru. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. The International Union for Conservation of Nature used to consider it a "vulnerable species" but has changed this assessment to "data deficient" because so little is known about the animal and the threats it faces.
Dasypus is the only extant genus in the family Dasypodidae. Its species are known as long-nosed or naked-tailed armadillos. They are found in South, Central, and North America, as well as on the Caribbean islands of Grenada, Trinidad and Tobago. Members of Dasypus are solitary and primarily nocturnal to avoid temperature extremes and predation. They exist in numerous habitats ranging from brush to grassland areas and are mainly insectivorous.
The eastern swamp crayfish is a species of small freshwater crayfish from coastal New South Wales, Australia. It is distinguished from related species by large genital papilla on the males, large raised postorbital ridges, a laterally compressed carapace, and elongated chelae.
Chlamyphoridae is a family of cingulate mammals. While glyptodonts have traditionally been considered stem-group cingulates outside the group that contains modern armadillos, there had been speculation that the extant family Dasypodidae could be paraphyletic based on morphological evidence. In 2016, an analysis of Doedicurus mtDNA found it was, in fact, nested within the modern armadillos as the sister group of a clade consisting of Chlamyphorinae and Tolypeutinae. For this reason, all extant armadillos but Dasypus were relocated to a new family.
