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. (Some of their much larger cingulate relatives, the pampatheres and chlamyphorid glyptodonts, made the same journey.)

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. 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.{{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 }}

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.

In common with other xenarthrans, armadillos, in general, have low body temperatures of {{convert|33|-|36|C}} and low basal metabolic rates (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).

The armor is formed by plates of dermal bone covered in relatively small overlapping epidermal scales called "scutes" which are composed of keratin.{{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}} The scutes are held together by collagen fibres that can contract to curve following the armadillo's body shape.{{cite journal |last1=Chen |first1=Irene H. |last2=Kiang |first2=James H. |last3=Correa |first3=Victor |last4=Lopez |first4=Maria I. |last5=Chen |first5=Po-Yu |last6=McKittrick |first6=Joanna |last7=Meyers |first7=Marc A. |title=Armadillo armor: Mechanical testing and micro-structural evaluation |url=https://www.sciencedirect.com/science/article/abs/pii/S1751616110001888 |journal=Journal of the Mechanical Behavior of Biomedical Materials |date=July 2011 |volume=4 |issue=5 |pages=713–722 |doi=10.1016/j.jmbbm.2010.12.013}}{{rp|713–715}} The skin of an armadillo can glow under ultraviolet light.{{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}}

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. 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.

The diets of different armadillo species vary, but consist mainly of insects, grubs, and other invertebrates. 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 grubs, and to dig dens. The nine-banded armadillo prefers to build burrows in moist soil near the creeks, streams, and arroyos around which it lives and feeds.

File:Mani armadilli.png

Armadillos have very poor eyesight, and use their keen sense of smell to hunt for food. 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 premolars and molars, but usually have no incisors or canines. The dentition of the nine-banded armadillo is P 7/7, M 1/1 = 32.

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.

Armadillos have short legs, but can move quite quickly. The nine-banded armadillo is noted for its movement through water, 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.

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), 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.

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.){{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}} Humans can acquire a leprosy infection from armadillos by handling them or consuming armadillo meat.{{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}} Armadillos are a presumed vector and natural reservoir for the disease in Texas, Louisiana and Florida.{{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.

The armadillo is also a natural reservoir for Chagas disease.

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. 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.

Even though they have a leathery, tough shell, armadillos, (mainly Dasypus) are common roadkill due to their habit of jumping 3–4 ft vertically when startled, which puts them into collision with the underside of vehicles.{{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}} 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.

In certain parts of Central and South America, armadillo meat is eaten; it is a popular ingredient in Oaxaca, Mexico.
