Have you ever seen an armadillo? They are mammals that have leathery armour shells?
Oh yeah those invasive things are all over the place where I live!
Sounds about right. All armadillo species inhabit all types of environments all over the Americas.
Where did they originally come from?  I know they're invasive, I just don't know from where?
Armadillos are native to the Americas. That is why there are 21 different species. Some have a different amount of bands on their shell. That is how you can tell them apart.
Wow that many different species. So when I see one squished on the side of the road, I should count bands to see which species it is?
Haha yea, possibly. Some people find armadillos kind of cute. The Aztecs used to call them "turtle-rabbit".
