The most important difference between an aardvark and an armadillo is that an aardvark has a long snout, while an armadillo has a shorter one. An aardvark also has longer claws than an armadillo, which it uses to dig into soil for food. Armadillos have hard shells made of keratin, while aardvarks have soft skin covered in hair. Aardvarks also have more teeth than an armadillo.
