About the armadillo

Armadillos are mammals of the Americas covered in bony plates under a leathery skin, and the roughly 20 species range from the pink fairy armadillo, about 12 centimetres long, to the giant armadillo, which can weigh over 30 kilograms. Only the three-banded armadillos can roll into a complete ball; the nine-banded armadillo, the one species found in the United States, instead jumps straight up when startled and has spread steadily north since the 1850s. Nine-banded females almost always give birth to identical quadruplets from a single egg.

Five things to know

  1. Armadillos are the only mammals with a complete hard shell made of bony plates.
  2. The Nine-banded Armadillo has rapidly expanded its range into the southern United States.
  3. Giant Armadillos can have up to 100 small teeth—more than any other terrestrial mammal.
  4. Pink Fairy Armadillos are so elusive that very little is known about their wild populations.
  5. Some armadillo species (like the Three-banded) can roll into a perfect ball for defense.
