The greater fairy armadillo (Calyptophractus retusus), also known as Burmeister's armadillo or the Chacoan fairy armadillo, is a species of armadillo in the family Chlamyphoridae. It is found in Argentina, Bolivia, and Paraguay. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. It is threatened by habitat loss and persecution. [2] It is the only species in the genus Calyptophractus. [1]

Description

The greater fairy armadillo is a small species, growing to a length of from 140 to 175 millimetres (5.5 to 6.9 in) with a tail about 35 millimetres (1.4 in) long and weighing up to a kilogram (2.2 lb). Like other armadillos it has bands of armour on its dorsal (upper) surface but, in common with the pink fairy armadillo Chlamyphorus truncatus but unlike most other armadillos, these bands are fused to its pelvis and spine. They are soft in texture and are linked together with skin which gives flexibility to the body. They come to an abrupt end at the rear of the body. The ventral surface is clad in dense, woolly hair and there are some sparse hairs on the dorsal surface as well. The forefeet are scoop-shaped and have curved claws, and the hind feet have sharp claws for burrowing. [3]

Distribution and habitat

The greater fairy armadillo is native to the Gran Chaco region of northern Argentina, central and south-eastern Bolivia and western Paraguay. It inhabits dry grassy areas and is found only in places with light sandy soils in which it can burrow. [2]

Behaviour

The behaviour of the greater fairy armadillo has been little studied. It is an expert tunneller and spends most of its time in the shallow burrows that it excavates and is seldom seen above ground during the day. If disturbed, it can bury itself rapidly, and may block the entrance to its burrow with its hindermost plates. It has an omnivorous diet and feeds on worms, insect larvae, insects, snails, roots and seeds. [3]

The breeding habits of this species are largely unknown. After mating has taken place, the fertilised egg may remain in the uterus for several months before implantation takes place. The egg may then divide and up to four embryos may develop from a single fertilised egg. The gestation period is probably about four months as in other species of armadillo. The young are precocial and can move about within a few hours of birth. Their body armour does not harden until they are a few weeks old and they are weaned about the same time. They become sexually mature at between six months and one year. [3]

Status

At one time the greater fairy armadillo was listed by the IUCN as "Near Threatened" because of the loss of its habitat but in 2010, its status was changed to "Data Deficient" on the grounds that the animal was insufficiently known for it to be properly evaluated. Its distribution is quite patchy and in some areas of the Guarani people, it is persecuted on sight due to a traditional belief that it is an animal of ill omen of death, or the spirit of a dead baby. [4] [2] However, it is present in some nature reserves and national parks where it should be undisturbed by humans. [2]

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 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.

<span class="mw-page-title-main">Nine-banded armadillo</span> Type of mammal

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.

<span class="mw-page-title-main">Chlamyphoridae</span> Family of armadillos

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.
