Reproduction
Mating takes place during a two- to three-month-long mating season, which occurs from July–August in the Northern Hemisphere and November–January in the Southern Hemisphere. A single egg is fertilized, but implantation is delayed for three to four months to ensure the young will not be born during an unfavorable time. Once the zygote does implant in the uterus, a gestation period of four months occurs, during which the zygote splits into four identical embryos, each of which develops its own placenta, so blood and nutrients are not mixed between them. After birth, the quadruplets remain in the burrow, living off the mother’s milk for approximately three months. They then begin to forage with the mother, eventually leaving after six months to a year.
Nine-banded armadillos reach sexual maturity at the age of one year, and reproduce every year for the rest of their 12–15 year lifespans. A single female can produce up to 56 young over the course of her life. This high reproductive rate is a major cause of the species’ rapid expansion.

Famous quotes containing the word reproduction:
“Were I called on to define, very briefly, the term Art, I should call it “the reproduction of what the Senses perceive in Nature through the veil of the soul.” The mere imitation, however accurate, of what is in Nature, entitles no man to the sacred name of “Artist.””
—Edgar Allan Poe (1809–1845)
“Although Samuel had a depraved imagination—perhaps even because of this—love, for him, was less a matter of the senses than of the intellect. It was, above all, admiration and appetite for beauty; he considered reproduction a flaw of love, and pregnancy a form of insanity. He wrote on one occasion: “Angels are hermaphrodite and sterile.””
—Charles Baudelaire (1821–1867)
“The chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproduction into social creativity.”
—Lewis Mumford (1895–1990)
