Theria. Marsupialia. Placentalia. A mammal (from Latin mamma 'breast') [1] is a vertebrate animal of the class Mammalia ( / məˈmeɪli.ə / ). Mammals are characterized by the presence of milk -producing mammary glands for feeding their young, a neocortex region of the brain, fur or hair, and three middle ear bones.
The Boundary Fire was a 2017 wildfire in Arizona that burned 17,788 acres (7,199 ha) of the Coconino and Kaibab National Forests. The fire was ignited on June 1 when lightning struck a spot on the northeast side of Kendrick Peak within the Coconino National Forest. The fire spread rapidly because of high temperatures, steep terrain, leftovers ...
The tomato ( / təmeɪtoʊ / or / təmɑːtoʊ /) is the edible berry of the plant Solanum lycopersicum, [1] [2] commonly known as the tomato plant. The species originated in western South America, Mexico, and Central America. [2] [3] The Nahuatl word tomatl gave rise to the Spanish word tomate, from which the English word tomato derives.

The word armadillo means "little armored one" in Spanish; it is derived from "armadura" (armor), with the diminutive suffix "-illo" attached. While the phrase "little armored one" would translate to "armadito" normally, the suffix "-illo" can be used in place of "-ito" when the diminutive is used in an approximative tense. The Aztecs called them āy...

Below is a recent simplified phylogeny of the xenarthran families, which includes armadillos, based on Slater et al. (2016) and Delsuc et al. (2016).The dagger symbol, "†", denotes extinct groups.
Recent genetic research suggests that an extinct group of giant armored mammals, the glyptodonts, should be included within the lineage of armadillos, having diverged some 35 million years ago, more recently than previously assumed.
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 Amer...
Size
The smallest species of armadillo, the pink fairy armadillo, weighs around 85 g (3.0 oz) and is 13–15 cm (5.1–5.9 in) in total length. The largest species, the giant armadillo, can weigh up to 54 kg (119 lb), and can be 150 cm (59 in) long.
Diet and predation
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 arroyosaround which it lives and feeds. Armadillos have very poor eyesight, and use their keen sense of smell to hu...
Body temperature
In common with other xenarthrans, armadillos, in general, have low body temperatures of 33–36 °C (91–97 °F) 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).
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 34 °C (93 °F), similar to human skin.) Humans can acqu...
Culture
Armadillo shells have traditionally been used to make the back of the charango, an Andean luteinstrument. In certain parts of Central and South America, armadillo meat is eaten; it is a popular ingredient in Oaxaca, Mexico. During the Great Depression, Americans were known to eat armadillo, known begrudgingly as "Hoover hogs", a nod to the belief that President Herbert Hooverwas responsible for the economic despair facing the nation at that time. A whimsical account of The Beginning of the Ar...
