Armadillos do not lay eggs because they are mammals who give birth to live young. These baby armadillos develop from the same fertilized egg, use the same placenta and number from one to three. This is true except in the case of the genus Dasypus.
The Dasypus armadillo produces from two to 12 embryos from one egg. The offspring of the Dasypus armadillo are born from identical embryos and they share the same sex at each birth.
Armadillos have poor eyesight. They use the senses of hearing and smelling to detect both danger and food. Armadillos eat spiders, earthworms, scorpions and other invertebrates.
