The Barbary macaque

The Barbary macaque (Macaca sylvanus), also known as Barbary ape or magot, is a macaque species native to the Atlas Mountains of Algeria and Morocco along with a small population of uncertain origin in Gibraltar. It is one of the best-known Old World monkey species.
Barbary macaques are Europe's only species of primate. ... One thing you'll notice about macaques is that they don't seem to have a tail. They actually have what's known as a 'vestigial' tail. This means that over time the macaque has evolved and the tail has all but disappeared as it's no longer required.
