Dasypus
''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 most common and widespread of the ''Dasypus'' species is the nine-banded armadillo (''Dasypus novemcintus''), which is commonly used in the study of leprosy due to its unique ability to contract the disease. Description ''Dasypus'' are xenarthran mammals known for their hard armor like shell, called a carapace. Their ossified dermal plates compose a series of six to eleven movable bands covered by leathery keratinous skin, which surrounds and protects the body. A thin epidermal layer separates each of the armor bands, and jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armadillos
Armadillos (meaning "little armored ones" in Spanish) 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. Armadillos are characterized by a leathery armor shell and long, sharp claws for digging. They have short legs, but can move quite quickly. The average length of an armadillo is about , including its tail. The giant armadillo grows up to and weighs up to , while the pink fairy armadillo has a length of only . When threatened by a predator, '' Tolypeutes'' species frequently roll up into a ball; they are the only species of armadillo capable of this. Etymology ...

Dasypus Bellus
''Dasypus bellus'', the beautiful armadillo, is an extinct armadillo species endemic to North America and South America from the Pleistocene, living from 1.8 mya—11,000 years ago, existing for approximately . Slightly larger than its living relative, the nine-banded armadillo, its fossils are known from Florida and records extend west to New Mexico and north to Iowa and Indiana. Description ''D. bellus'' had small, simple, peg-like teeth similar to ''D. novemcinctus.'' Its maximum length was approximately long, twice the size of the nine-banded armadillo. The osteoderms of the shell and the limb bones of ''D. bellus'' are about two to two and a half times the extent of those of the living modern nine-banded armadillo ''D. novemcinctus''. The small ''D. bellus'' overlapped in size with the ''D. novemcinctus''. The body size of ''D. bellus'' decreased during the late Pleistocene, suggesting that its body size was variable.

Dasypus Novemcinctus
The nine-banded armadillo (''Dasypus novemcinctus''), 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.

Dasypus Hybridus
The southern long-nosed armadillo (''Dasypus hybridus'') is a species of armadillo native to South America. Description Among the smallest of the long-nosed armadillos, individuals of the southern species measure about in head-body length, with a tail about long. With no discernible sexual dimorphism, both males and females weigh about . The upper body, tail, and upper surface of the head are covered by a dark grey carapace of bony scales and have very little hair. The central part of the carapace is divided into a number of movable bands; there are usually seven such bands, but many individuals have just six, while a few have eight. The scales on the main shields, over the shoulders and hips, are hexagonal and about across, while those on the bands are rectangular and marked with a V-shaped groove that divides them into three triangular sections. The scales on the head are variable in shape. The tail has a number of distinct rings for about two-thirds of its length, and a sl ...

Xenarthra
Xenarthra (; from Ancient Greek ξένος, xénos, "foreign, alien" + ἄρθρον, árthron, "joint") is a major clade of placental mammals native to the Americas. There are 31 living species: the anteaters, tree sloths, and armadillos. Extinct xenarthrans include the glyptodonts, pampatheres and ground sloths. Xenarthrans originated in South America during the late Paleocene about 60 million years ago. They evolved and diversified extensively in South America during the continent's long period of isolation in the early to mid Cenozoic Era. They spread to the Antilles by the early Miocene and, starting about 3 Mya, spread to Central and North America as part of the Great American Interchange. Nearly all of the formerly abundant megafaunal xenarthrans became extinct at the end of the Pleistocene. Xenarthrans share several characteristics not present in other placental mammals, which suggest their ancestors were subterranean diggers for insects. The name Xenarthra deriv ...

Dasypus Yepesi
Yepes's mulita or the Yungas lesser long-nosed armadillo (''Dasypus mazzai)'' is a species of armadillo in the family Dasypodidae. It is endemic to Argentina and Bolivia. Its natural habitat is subtropical dry forests. The species was renamed ''D. yepesi'' because the type of ''D. mazzai'' was suspected to correspond of other species of ''Dasypus'', which it was later proved wrong, becoming ''D. yepesi'' a synonym of ''D. mazzai''. Geographic Range Yepes's mulita is found in the Jujuy and Salta provinces of Argentina, however its range my extend to parts of Bolivia and Paraguay Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America.

Dasypus Septemcinctus
The seven-banded armadillo (''Dasypus septemcinctus''), also known as the Brazilian lesser long-nosed armadillo, is a species of armadillo from South America found in Paraguay, Argentina, Bolivia and Brazil. It is a solitary nocturnal, terrestrial animal, living mostly in dry habitats, outside of rainforest regions. Description Long-nosed armadillos have a broad, depressed body, an obtusely pointed rostrum, long, pointed ears and short legs. The carapace consists of two immobile plates, separated by six or seven movable bands, which are connected to each other by a fold of hairless skin. The carapace is mostly blackish, hairless and with the scales of the anterior edge of the movable bands not notably different in colour from the rest of the dorsum. Lateral scutes A scute or scutum (Latin: ''scutum''; plural: ''scuta'' "shield") is a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians, and the feet of birds.

Dasypus Pilosus
The hairy long-nosed armadillo or woolly armadilloGardner AL 2007 Mammals of South America Vol 1: Marsupials, Xenarthrans, Shrews and Bats- University of Chicago Press, Chicago. (''Dasypus pilosus'') 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. Description The hairy long-nosed armadillo is poorly known. Like other species of ''Dasypus'', it has a hard armour-like shell, called a carapace. The armour consists of ossified dermal plates composed of a number of movable bands covered by leathery skin. The rostrum is long and slender and is more than half the length of the head. There are long, hairless ears and a slender tail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
