The Barbary Macaque (Macaca sylvanus) is a macaque with just a stub of a tail. Foun in the Atlas Mountains of Algeria and Morocco with a small, possibly introduced, population in Gibraltar, the Barbary Macaque is one of the best-known Old World monkey species. Besides humans, they are the only primates that live freely in Europe. Although the species is commonly referred to as the "Barbary Ape", the Barbary Macaque is a true monkey, not an ape. Confusion as to the name could have arisen from the fact that apes are tailless.
