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. [ 32 ] [ 33 ] [ 34 ] Because they are always genetically identical, the group of four young provides a good subject for scientific, behavioral, or medical tests that need ...
The nine-banded armadillo has been rapidly expanding its range both north and east within the United States, where it is the only regularly occurring species of armadillo. The armadillo crossed the Rio Grande from Mexico in the late 19th century, and was introduced in Florida at about the same time by humans.
Nine-banded armadillo (Dasypus novemcinctus). Cingulata is an order of armored placental mammals.Members of this order are called cingulates, or colloquially, armadillos.They are primarily found in South America, though the northern naked-tailed armadillo is found mainly in Central America and the nine-banded armadillo has a range extending into North America.

In mammals, all intact developmentally typical males have a penis, but the clitoris in the females of the following species is sufficiently enlarged that it is usually termed a pseudo-penis: spotted hyena, [1] [2] juvenile fossa, [3] binturong, [4] lemur [5] and spider monkey.
†Beautiful armadillo (Dasypus bellus) is an extinct armadillo species found in North and South America about 2.5 million to 11,000 years ago. It is much larger than current-day species at about 2.5 times the size of the normal nine-banded armadillo and had much thicker, more robust armor. [15] [16]
The Brazilian three-banded armadillo (Tolypeutes tricinctus) is an armadillo species endemic to eastern Brazil, where it is known as tatu-bola (Portuguese pronunciation: [tɐˈtu ˈbɔlɐ], lit. ball armadillo).

[6] Its body is dark brown in color, with a lighter, yellowish band running along the sides, and a pale, yellow-white head.
Two groups of cingulates much larger than extant armadillos (maximum body mass of 45 kg (100 lb) in the case of the giant armadillo [2]) existed until recently: pampatheriids, which reached weights of up to 200 kg (440 lb) [3] and chlamyphorid glyptodonts, which attained masses of 2,000 kg (4,400 lb) [4] or more.
