The group currently includes armadillos 2-toed sloths 3-toed sloths , and anteaters , placed in four families containing 29 species. These animals are mostly insectivores and herbivores of small to medium body size (up to around 60 kg). In the past, however, xenarthrans were much more diverse and numerous. They radiated into around a dozen families, including not only the groups known today, but also such animals as giant ground sloths, some of which were larger than elephants; glyptodonts, reaching 3 m in length and the most heavily armored vertebrates that ever existed; and a large number of smaller grazing and browsing forms. Several groups of xenarthrans successfully crossed the Central American land bridge to North America when it formed in the Pliocene; these included a number of kinds of ground sloths and armadillos. Only one species, however, an armadillo ( Dasypus novemcinctus ), is still alive today.

Phylum: Chordata Subphylum: Vertebrata Class: Mammalia The Order xenarthra includes armadillos, anteaters, and sloths. Although these mammals may seem very different on the outside, they have several similarities in their skeletons. Animals in this order either have no teeth, or have a reduced number of teeth. They all lack incisors and canines . Those species that have teeth only have simple molars . There are three families with 29 species world-wide, but only one species is found in the southeastern United States. The Family Dasypodidae . This family includes 20 species of armadillos. They all have a long snout with peg-like molar and pre-molar teeth, small eyes, and large ears. Their body is heavy, with short legs and a long tail. They have bony scutes that form a hard shell-like covering over their body. They have strong recurved claws that they use to dig burrows and food. The single species found in the southeastern United States was introduced into Florida in the 1900s and has since expanded its range northward into Georgia, Alabama, and Mississippi.

Introduction to the Xenarthra anteaters, armadillos, and sloths Anteaters, armadillos, and sloths are a group of eutherian mammals known as the Xenarthra. They were once placed in the order Edentata and are still often referred to as edentates , a word that means "toothless." Although xenarthrans such as anteaters are indeed toothless, the giant armadillo has as many as 100 teeth, more than almost any other mammal. Members of the mammalian group Edentata not only include the 31 living species of armadillos, true anteaters, and tree sloths, but also contain eight families of extinct ground sloths and armadillo-like animals. Together, the living families and extinct families constitute the Xenarthra. Living xenarthrans : On the left, a sloth. At right, a hairy armadillo from Santa Cruz, Argentina.

THE ORDER XENARTHRA: Southern North America and South America is their distribution, and the Xenarthrans consist of 29 species in four distinct families: anteaters, sloths (two families - two and three-toed), and armadillos. Anteaters are toothless, sloths and armadillos lack incisors and canines but do have simple cheek teeth that lack enamel and grow continuously from the roots as the tops wear down. Armadillos have up to 100 such teeth. Their skulls are elongated and the brain small and narrow. But other similarities seem difficult to come by. How could three such different-looking types of animals be related? It is in the vertebrae of the lumbar region where they have an extra articulation. It is a skeletal feature peculiar to this order, and "Xenarthra" means "strange joints." Their specially strengthened backbone may have evolved from the defense posture that anteaters assume. If threatened, the animal stands erect on its hind legs and braces itself with its strong, heavy tail, forming a tripod. It then proceeds to lash out with its powerful arms, slashing with its formidable claws.

Giant anteater Order Xenarthra: sloths, armadillos, and anteaters The old name for this order, Edentata (="toothless") has been replaced by the more appropriate term Xenarthra. Among living species, only the anteaters (superfamily Myrmecophagoidea) are toothless. All living species are New World mammals, the largest being the giant anteater Myrmecophaga tridactyla (shown at left), which reaches a length of 120 cm/3' 7" and a weight up to 40 kg/83 pounds. Xenarthra share the following characters: Females have a common urogenital duct; toes all strongly clawed; testes interior, between bladder and rectum; double posterior vena cava. Giant anteaters use a long, sticky tongue to capture the huge quantities of ants and termites. The huge front claws easily open concrete-hard termite mounds, and serve as effective weapons o self-defense. Reproduction and copying for non-commercial purposes is encouraged.

Pangolins Sloth Bears Xenarthra versus Edentata: Two and Three-Toed Sloths are merely two genera in an order that includes twenty-nine species in all. Collectively, the mammals in the Xenarthra order as well as the Pangolins in the order "Pholidota" are generally called "Edentates", referring to the now outdated order Edentata. The term "Edentate" strictly means "without teeth", which is not a very accurate description of these mammals; only the eleven species of Anteaters and Pangolins are completely toothless, while Sloths and Armadillos have rudimentary molars and pre-molars, or "grinding" teeth. More recently the order has been renamed "Xenarthra" by scientists, referring not to a lack of teeth but instead to specific adaptions to the lumbar vertebrae, also known as "xenarthrales". History: 60 million years ago, early Xenarthrans had already distinguished themselves by their additional articulations in the lumbar vertebrae. The additional support there help specifically with the activity of digging, which especially help armadillos. Other characteristics that separate the Edentates from other mammals are a lack of true canine or incisor teeth (thus suggesting "toothless"). Due to the virtual isolation of South America 65 million years ago, the Edentates were allowed to radiate and establish many stunning and varied genera, many suggesting the animal families we now today.

They are by far the most diverse group of xenarthrans, with 20 species in 8 genera. To most of us, the defining feature of armadillos is their " shell ." This structure consists of bony scutes covered with thin keratinous (horny) plates. The scutes cover most of the dorsal surface of the body. They are interrupted by bands of flexible skin at least behind the head, and in most species, at intervals across the back as well. The belly is soft and unprotected by bone except insofar as some species are able to curl into a ball. Hairs project from the areas between scutes, and in some species the ventral surface is densely hairy as well. The limbs have irregular horny plates covering at least parts of their surfaces; they also may be hairy. The top of the head is always covered by a shield of keratin-covered scutes, and the tail is covered by bony rings. Armadillos vary in size from the tiny fairy armadillo (120 gms) to the giant armadillo (60 kg). Body length ranges from about 125 mm to around 1 m. The snout is short and triangular in some species, long and tubular in others. Some species have large external ears, others do not. The eyes generally seem small. All armadillos have powerful forelimbs, with 3-5 digits (depending on the species) tipped with heavy, curved

Two-toed sloths are found in Central America, throughout northern South America and in the Amazon basin. Two toed sloths are medium-sized animals, with a body slightly more than half a meter in length and weight up to around 9 kg. They are covered with long, usually pale gray-brown fur (paler on the head) that takes on a greenish hue due to symbiotic algae living on the hairs. Under the coarse outer fur, the pelage grades into a layer of finer, shorter underfur. External ears are much reduced in size. The forelimbs and hindlimbs are long, with the forelimbs somewhat longer than the hindlimbs (but the difference is not as extreme as it is in three-toed sloths, Bradypodidae ). The forelimbs end in two large, curved

It is distributed through Central and South America, south to southern Brazil. Three-toed sloths weigh 3 - 5 kg; their bodies run around 0.5 m in length. They are covered with dense, long, shaggy fur made up of thick hairs with longitudinal grooves. Beneath the overfur is short underfur of finer texture. Some have unusually long neck hairs, which form a mane. Individual hairs are directed so that they point towards the ground when the animal hangs beneath a branch, perhaps helping it shed rain. Three-toed sloths are mostly tan or yellow-brown in color (with some contrasting markings on the face and mane), and the grooves in the individual hairs contain algal cells that give the coat a greenish cast. Bradypodids have a short and very stout tail. The forearms of three-toed sloths are longer than the hind limbs. Fore and hind feet have three enlarged, hook-like

All anteaters have long, tapered snouts; that of Myrmecophaga is extraordinarily elongated. The tongue is also long. Anteaters secrete a sticky substance from their salivary glands that coats the tongue when they feed. The ears are small and rounded, and the eyes are small. The tails are long and prehensile in 2 of the 3 genera. The forelimbs are remarkable. They have 5 digits, each with long and sharp claws , the third claw being especially well developed. The hind feet are less specialized, with 4 or 5 toes and strong but not remarkable claws.

Its members are bizarre creatures and highly specialized in structure and habits. The toothless anteaters are provided with heavy claws to tear apart termite nests and a long, slender, protrusile, sticky tongue to capture the insects. The slow-moving, plant-eating sloths are tree dwellers, with a rudimentary tail and only two or three toes on each foot. In the large group of armadillos, the presence of a bony carapace is unique among mammals. The Order is divided into three families, all of which are restricted to Central and South America with the exception of one species, the nine-banded armadillo, which ranges north to the United States.

20. XENARTHRA: Sloths, Anteaters, Armadillos Order xenarthra. xenarthrans. The living xenarthra are sometimes dividedinto the following groups (Barlow 1984; Hall 1981; Romer 1968) http://www.press.jhu.edu/books/walkers_mammals_of_the_world/xenarthra/xenarthra.

Order Xenarthra Xenarthrans This order, the living components of which are 4 families , 13 genera, and 30 species, inhabits the south-central and southeastern United States, Mexico, Central America, and South America. At least 3 additional genera and 3 species are thought to have occurred in the West Indies until about 500 years ago. The name Xenarthra usually has been applied at the subordinal level, with the name Edentata being given to an order that included the Xenarthra and the supposedly ancestral suborder Palaeanodonta. However, Glass 1985) explained that the Palaeanodonta are ancestral to the Pholidota, not to the Xenarthra, and that the name Edentata should be considered a synonym of the name Pholidota. The name Xenarthra also has been used at the ordinal level by Barlow Engelmann 1985), and Wetzel a ), though not by Corbet and Hill 1986). The living Xenarthra are sometimes divided into the following groups ( Barlow Hall Romer Infraorder Pilosa (sloths) Superfamily Megalonychoidea Family Megalonychidae Family Bradypodidae Infraorder Vermilingua (anteaters) Superfamily Myrmecophagoidea Family Myrmecophagidae Infraorder Cingulata (armadillos) Superfamily Dasypodoidea Family Dasypodidae.
