The nine-banded armadillo always gives birth to 4 identical quadruplets. They are produced from a single egg which splits in four, meaning the babies will all be the same gender.
Armadillos are able to delay implantation of the fertilised egg at times of stress; it is thought this can be delayed for as long as 2 years!
Baby armadillos have soft leathery skin which hardens after a few weeks.
Where armadillos live is dependent on soil type, they prefer sandy or loam soils which are loose and porous, making it easier to dig for food and make burrows.
