PLATED FOR PROTECTION
       The armadillo resembles a mammalian
       tank, with its bony scutes (plates) of armor
       covered by horn. The scutes develop from
       skin, and even the tail is armored. Only
       some of the 20 armadillo species can
       roll up into a ball. An alternative
       defense is to “dig in” to protect the
       softer, vulnerable underparts.  NO ENTRY SIGN
                                  The three-banded armadillo
                                  (left) is able to roll itself up
                                  completely, while the pink fairy
                                  armadillo (below) digs a hole in
                                  which it hides. Its armored
                                  bottom acts as a barrier, rather
                                  like a cork in a bottle.
