Armadillos are mammals of the New World with a leathery armor shell that cover almost entirely their body in normal conditions and entirely, when they take the shape of a ball for protection. The meaning of the word armadillo is something like "little armored one" in Spanish. Today, all armadillos species are still present in South America. They are particularly diverse in Paraguay (where eleven species exist) and surrounding areas. Many species are endangered or critically endangered. They are now widely know thanks to the fact that an armadillo is the official mascot of the Football World Cup celebrated in 2014 in Brazil.
