Most monkeys live in tropical rainforests where it never gets cold. Barbary macaques are different - they live up in the mountains, where it snows in winter. Their thick fur keeps them warm, and they often huddle together in a furry group to share heat when it gets icy.
They live in big family troops of 20 to 40 monkeys. Aunts, uncles and older brothers and sisters all help look after the babies - which is unusual in the monkey world. A baby macaque often gets passed around like a parcel for cuddles.
Barbary macaques are clever. They use rocks to crack open snails, they remember which trees fruit at which time of year, and they have been seen using leaves as little umbrellas in the rain.
Sadly, there are not many Barbary macaques left in the wild - probably fewer than 10,000. Scientists and forest rangers in Morocco work hard to protect their cedar forest home, and projects in schools nearby teach children all about them.
