Do some armadillos have club tails?

No, the only armadillo species with a club tail is the club-tailed armadillo (Euphractus sexcinctus). This armadillo is usually found in the dry shrublands of Argentina, Bolivia, and Paraguay. The club-tailed armadillo can be distinguished from other armadillos by the armored club at the end of its tail. This club is used for digging and defense, and it can be quite effective.
