response: I don't know about that, but I know there are 21 species of armadillo, distinguished by how many bands are on their armor. Do you know which species is out your way?
original_response: I've heard that too, though that's probably the case only with certain species, of which there are at least 21 extant.
history: I live in the South where I see dead Armadillos on the road quite often. I see, that's probably because armadillos are native to North and South America. Is there anything else you'd like to know about them? I have heard that they may be carriers of several different diseases that are harmful to people.
knowledge: About nine extant genera and 21 extant species of armadillo have been described, some of which are distinguished by the number of bands on their armour.
