'''Armadillos''' (meaning "little armored ones" in [[Spanish language|Spanish]]) are [[New World]] [[placental]] [[mammal]]s in the [[order (biology)|order]] [[Cingulata]]. They form part of the superorder [[Xenarthra]], along with the [[anteater]]s and [[sloth]]s. 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. 
 
Living armadillos are characterized by a leathery [[armour (anatomy)|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 {{convert|75|cm|in|abbr=on}}, including its tail. The [[giant armadillo]] grows up to {{convert|150|cm|in|abbr=on}} and weighs up to {{convert|54|kg|lb|abbr=on}}, while the [[pink fairy armadillo]] has a length of only {{convert|13|–|15|cm|in|sigfig=1|abbr=on}}. When threatened by a predator, ''[[Tolypeutes]]'' species frequently roll up into a ball; they are the only species of armadillo capable of this.

Recent genetic research has shown that the [[megafauna]]l [[glyptodont]]s (up to {{Convert|1.5|m|ft}} tall with maximum body masses of around 2 tonnes), which became extinct around 12,000 years ago are true armadillos more closely related to all other living armadillos than to ''[[Dasypus]]'' (the long-nosed or naked-tailed armadillos). Armadillos are currently classified into two families, [[Dasypodidae]], with ''Dasypus'' as the only living genus, and [[Chlamyphoridae]], which contains all other living armadillos as well as the glyptodonts.<ref>{{Cite journal |last1=Mitchell |first1=Kieren J. |last2=Scanferla |first2=Agustin |last3=Soibelzon |first3=Esteban |last4=Bonini |first4=Ricardo |last5=Ochoa |first5=Javier |last6=Cooper |first6=Alan |date=July 2016 |title=Ancient DNA from the extinct South American giant glyptodont Doedicurus sp.

==Evolution==
Recent genetic research suggests that an extinct group of giant armored mammals, the [[glyptodont]]s, should be included within the lineage of armadillos, having diverged some 35 million years ago, more recently than previously assumed.<ref name =AMNH2016>{{cite web|url=http://www.amnh.org/explore/news-blogs/research-posts/study-finds-relationship-between-glyptodonts-modern-armadillos|title=Study finds relationship between glyptodonts, armadillos|publisher=AMNH|access-date=2016-02-22|archive-date=28 February 2016|archive-url=https://web.archive.org/web/20160228051721/http://www.amnh.org/explore/news-blogs/research-posts/study-finds-relationship-between-glyptodonts-modern-armadillos|url-status=live}}</ref>

==Distribution==
Like all of the Xenarthra lineages, armadillos originated in [[South America]]. Due to the continent's former isolation, they were confined there for most of the [[Cenozoic]]. The recent formation of the [[Isthmus of Panama]] allowed a few members of the family to migrate northward into southern [[North America]] by the early [[Pleistocene]], as part of the [[Great American Interchange]].<ref name="Woodburne2010"/> (Some of their much larger [[Cingulata|cingulate]] relatives, the [[pampathere]]s and chlamyphorid [[glyptodont]]s, made the same journey.)<ref name="Woodburne2010"/>

Today, all extant armadillo species are still present in South America. They are particularly diverse in [[Paraguay]] (where 11 species exist) and surrounding areas. Many species are endangered. Some, including four species of ''[[Dasypus]]'', are widely distributed over the Americas, whereas others, such as [[Yepes's mulita]], are restricted to small ranges. Two species, the [[northern naked-tailed armadillo]] and [[nine-banded armadillo]], are found in Central America; the latter has also reached the United States, primarily in the south-central states (notably Texas), but with a range that extends as far east as [[North Carolina]] and [[Florida]], and as far north as southern [[Nebraska]] and southern [[Indiana]].<ref name=ExpRange/> Their range has consistently expanded in North America over the last century due to a lack of natural predators. Armadillos are increasingly documented in southern [[Illinois]] and are tracking northwards due to [[climate change]].<ref>{{Cite web |title=Armadillos have arrived in downstate Illinois and are heading north — yes, you might someday see an armadillo in your backyard |url=https://www.chicagotribune.com/entertainment/ct-ent-armadillos-arrive-illinois-20220504-hhzv7szssbfotkegaxb442xu2m-story.html |access-date=2022-05-17 |website=Chicago Tribune |date=14 May 2022 |language=en |archive-date=17 May 2022 |archive-url=https://web.archive.org/web/20220517155535/https://www.chicagotribune.com/entertainment/ct-ent-armadillos-arrive-illinois-20220504-hhzv7szssbfotkegaxb442xu2m-story.html |url-status=live }}</ref>

==Characteristics ==
===Size===
The smallest species of armadillo, the [[pink fairy armadillo]], weighs around {{convert|85|g|oz|abbr=on}} and is {{convert|13|-|15|cm|
|abbr=on}} in total length. The largest species, the [[giant armadillo]], can weigh up to {{convert|54|kg|lb|abbr=on}}, and can be {{convert|150|cm|in|abbr=on}} long.<ref name=NatGeo/>

===Diet and predation===
The diets of different armadillo species vary, but consist mainly of [[insect]]s, grubs, and other [[invertebrate]]s. Some species, however, feed almost entirely on ants and termites.

They are prolific diggers. Many species use their sharp claws to dig for food, such as [[Larva|grubs]], and to dig dens. The [[nine-banded armadillo]] prefers to build burrows in moist soil near the creeks, streams, and [[arroyo (creek)|arroyos]] around which it lives and feeds.
[[File:Mani armadilli.png|thumb|right|Paws of a hairy and a giant armadillo]]
Armadillos have very poor eyesight, and use their keen sense of smell to hunt for food.<ref name=NatGeo/> They use their claws not only for digging and finding food but also for digging burrows for their dwellings, each of which is a single corridor the width of the animal's body. They have five clawed toes on their hind feet, and three to five toes with heavy digging claws on their fore feet. Armadillos have numerous cheek teeth which are not divided into [[premolar]]s and [[molar (tooth)|molar]]s, but usually have no [[incisor]]s or [[canine (tooth)|canine]]s. The [[dentition]] of the nine-banded armadillo is P 7/7, M 1/1 = 32.<ref name="Freeman&Genoways"/>

===Body temperature===
In common with other xenarthrans, armadillos, in general, have low [[Thermoregulation|body temperature]]s of {{convert|33|-|36|C}} and low [[basal metabolic rate]]s (40–60% of that expected in placental mammals of their mass). This is particularly true of types that specialize in using termites as their primary food source (for example, ''[[Priodontes]]'' and ''[[Tolypeutes]]'').<ref name="McNab"/>

===Skin===
The armor is formed by [[plate (anatomy)|plates]] of [[dermal bone]] covered in relatively small overlapping epidermal scales called "[[scute]]s" which are composed of keratin.<ref name=Yates>{{cite web|url=https://biologydictionary.net/armadillo/|title=Armadillo|last=Yates|first=Paige|date=30 October 2020|website=BiologyDictionary.net|publisher=Biology Dictionary|access-date=8 September 2021|quote=The plates of bone are covered in small overlapping epidermal scales called scutes, which are composed of keratin.|archive-date=8 September 2021|archive-url=https://web.archive.org/web/20210908182815/https://biologydictionary.net/armadillo/|url-status=live}}</ref> The skin of an armadillo can glow under ultraviolet light.<ref>{{Cite web |last1=Travouillon |first1=Kenny |last2=Cooper |first2=Christine Elizabeth |last3=Bouzin |first3=Jemmy |last4=Umbrello |first4=Linette |last5=Lewis |first5=Simon |last6=Conversation |first6=The |title=From glowing cats to wombats, fluorescent mammals are much more common than you'd think |url=https://phys.org/news/2023-10-cats-wombats-fluorescent-mammals-common.html |access-date=2023-10-06 |website=phys.org |language=en}}</ref>
Most species have rigid shields over the shoulders and hips, with a number of bands separated by flexible skin covering the back and flanks. Additional armor covers the top of the head, the upper parts of the limbs, and the tail. The underside of the animal is never armored and is simply covered with soft skin and fur.<ref name="EoM" /> This armor-like skin appears to be an important defense for many armadillos, although most escape predators by fleeing (often into thorny patches, from which their armor protects them) or digging to safety. Only the South American three-banded armadillos (''[[Tolypeutes]]'') rely heavily on their armor for protection.

===Defensive behavior===
When threatened by a [[predator]], ''Tolypeutes'' species frequently roll up into a ball. Other armadillo species cannot roll up because they have too many plates. When surprised, the North American nine-banded armadillo tends to jump straight in the air, which can lead to a fatal collision with the undercarriage or fenders of passing vehicles.<ref name=LOC/>

===Movement===
Armadillos have short legs, but can move quite quickly.  The nine-banded armadillo is noted for its movement through water,<ref name=McDonough2013/> which is accomplished via two different methods: it can walk underwater for short distances, holding its breath for as long as six minutes; or, to cross larger bodies of water, it can increase its buoyancy by swallowing air to inflate its stomach and intestines.<ref name=Vijayaraghavan/>

===Reproduction===
[[Gestation]] lasts from 60 to 120 days, depending on species, although the nine-banded armadillo also exhibits [[delayed implantation]], so the young are not typically born for eight months after mating. Most members of the genus ''[[Dasypus]]'' give birth to four [[monozygotic]] young (that is, identical quadruplets),<ref name=Bagatto2000/> but other species may have typical litter sizes that range from one to eight. The young are born with soft, leathery skin which hardens within a few weeks. They reach sexual maturity in three to twelve months, depending on the species. Armadillos are solitary animals that do not share their burrows with other adults.<ref name="EoM" />

==Armadillos and humans==

=== Science and education ===
Armadillos are often used in the study of [[leprosy]], since they, along with [[mangabey]] monkeys, rabbits, and mice (on their footpads), are among the few known species that can contract the disease systemically. They are particularly susceptible due to their unusually low body temperature, which is hospitable to the leprosy bacterium, ''[[Mycobacterium leprae]]''. (The leprosy bacterium is difficult to culture and armadillos have a body temperature of {{convert|34|C}}, similar to human skin.)<ref name="Truman">{{cite journal|last1=Truman|first1=Richard|title=Leprosy in wild armadillos|journal=Leprosy Review|date=2005|volume=76|issue=3|pages=198–208|doi=10.47276/lr.76.3.198 |url=http://www.lepra.org.uk/platforms/lepra/files/lr/sept05/lep198-208.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.lepra.org.uk/platforms/lepra/files/lr/sept05/lep198-208.pdf |archive-date=2022-10-09 |url-status=live|access-date=4 May 2017|pmid=16248207}}</ref> Humans can acquire a leprosy infection from armadillos by handling them or consuming armadillo meat.<ref name=NYT2011/><ref>{{Cite web |last=Guiden |first=Mary |date=June 2018 |title=New evidence that wild armadillos spread leprosy to humans |url=https://cvmbs.source.colostate.edu/new-evidence-that-wild-armadillos-spread-leprosy-to-humans/ |access-date=November 16, 2023 |website=Colorado State University}}</ref> Armadillos are a presumed [[Vector (epidemiology)|vector]] and [[natural reservoir]] for the disease in Texas, Louisiana and Florida.<ref>{{cite journal|title=Zoonotic Leprosy in the Southeastern United States|first1=Rahul|last1=Sharma|first2=Pushpendra|last2=Singh|first3=W.J.|last3=Loughry|first4=J.

Given that armadillos are native to the New World, at some point they must have acquired the disease from old-world humans.<ref name=NYT2011/><ref name="Truman 2011" />

The armadillo is also a [[natural reservoir]] for [[Chagas disease]].<ref name=Yaeger1988/>

The nine-banded armadillo also serves science through its unusual reproductive system, in which four genetically identical offspring are born, the result of one original egg.<ref name="ufl"/><ref name="valdosta"/><ref name="Hamlett1933"/> Because they are always genetically identical, the group of four young provides a good subject for scientific, behavioral, or medical tests that need consistent biological and genetic makeup in the test subjects. This is the only reliable manifestation of [[polyembryony]] in the class [[Mammalia]], and exists only within the genus ''Dasypus'' and not in all armadillos, as is commonly believed. Other species that display this trait include parasitoid wasps, certain flatworms, and various aquatic invertebrates.<ref name="valdosta" />

Even though they have a leathery, tough shell, Armadillos, (mainly ''Dasypus'') are common [[roadkill]] due to their habit of jumping 3–4&nbsp;ft vertically when startled, which puts them into collision with the underside of vehicles.<ref>{{Cite web|title=How high can a nine-banded armadillo jump?|url=https://www.loc.gov/item/how-high-can-a-nine-banded-armadillo-jump/|access-date=2020-08-31|website=Library of Congress}}</ref> Wildlife enthusiasts are using the northward march of the armadillo as an opportunity to educate others about the animals, which can be a burrowing nuisance to property owners and managers.<ref name="ufl" />

=== Culture ===
[[File:210_Museu_de_la_Música,_el_Bosc,_charango.jpg|thumb|A traditional charango made of ''armadillo'', today superseded by wooden charangos, in [[Museu de la Música de Barcelona]]]]
Armadillo shells have traditionally been used to make the back of the ''[[charango]]'', an [[Andean music|Andean]] [[lute]] instrument.
