Here's a breakdown:
* Nine-banded armadillos: The most common species in the US, they typically live 8-12 years in the wild.
* Other species: Other armadillo species, like the giant armadillo, can live up to 15 years in the wild.
* Captivity: Armadillos in captivity can live longer than their wild counterparts, with some reaching 20 years or more.
It's important to note that factors like predation, disease, and habitat loss can significantly shorten an armadillo's lifespan in the wild.
