I think I've found my new favorite armored mammal (yes, I break my favorites down into very narrow categories). This is the pink fairy armadillo (Chlamyphorus truncatus). Though the creature's name hints at the possibility that one of my five-year-old twin daughters might have named it, "it is found in central Argentina where it inhabits dry grasslands and sandy plains with thorn bushes and cacti." My daughters, to my knowledge, have never traveled there, and they, as a rule, steer clear of cacti.
This armadillo can bury itself in a matter of seconds if properly motivated (think prowling coyotes or teenage boys), and feeds mostly on ants and ant larvae. I can't think of anything wrong with this creature. It's armored, has massive claws, eats the pesky ant, and probably speaks with a suave Argentine accent. Can you ask for anything more?
