Diagnosis:  The Nine-banded Armadillo is a mammal but it has a hard outer shell that is made of true bone and bony rings on their tails. They weigh anywhere from 6 to 13 lbs and can range from 14 to 22 inches in length. They have short legs with claws made for digging to find food or shelter. Their teeth are peg-like and do not have an enamel coating. They have poor eyesight so they use their sense of smell to hunt.


Natural History: Mating usually takes place in July and August, but the embryo remains dormate until November. The armadillo is obligate polyembryony, which means the female only lays one egg and this one egg splits into four identical young, so the armadillo gives birth to four identical off spring. This species can have a life span of up to 15 years.


Distribution: This species is native to South America. This species now ranges from South America northward into the United States and can be found in Louisiana, Oklahoma, Kansas, Missouri, Arkansas, Mississippi, Alabama, South Carolina, Georgia and Texas.


Habitat: Armadillos live in temperate and warm climates, such as grasslands, rain forests and semi-deserts


Diet: Armadillos mainly eat small invertebrates, like grubs and ants, and small soft plants. They may also eat small bits of flesh from dread animals if they find them.


Conservation Status: Not threatened


Etymology: Armadillo is a Spanish word meaning ‘little armored one’, referring to the bony plates on it body
