Did you know...... Some fantastic facts about primates.

Charlotte Uhlenbroek meets the monkeys. At 3,000 metres up in the Simien mountains of Ethiopia, Charlotte encounters gelada baboons that live in groups of up to 800 individuals. The large lion-like males are busy attending to their harems and a lot of male posturing is going on. It looks fierce, but these are the teddy bears of the monkey world.

In Central America, Charlotte catches the attention of some laid-back howler monkeys by howling at them. Charlotte can't climb like the monkeys, so to get up into the canopy she dons a hard hat and harness and hauls herself up to get a monkey's eye view of the world.

Humans have the longest childhood of all animals, but young monkeys do stay with their parents for several years. In the remote mountains of central China, a baby golden monkey is the apple of everyone's eye. Like humans, older brothers and sisters want to hold the baby and play pass the parcel with it, until mum calls a halt to their game.

Also in China, Tibetan macaques are serious muggers that line up along the precarious path to the temples and operate a stop and search policy on pilgrims and tourists, grabbing food in exchange for a photo-opportunity. One 20-kilo macaque can cause a lot of damage, and when they gang up it's enough to start a riot. Every year, many people are bitten and some even fall off the cliff in a blind panic.

In a snowy valley in Japan, Charlotte is joined in a hot spring by a cheeky Japanese macaque. For a long time the Japanese have enjoyed bathing in the hot mountain springs, and back in the 1960s some young macaques joined them in the water. Eventually they had their own monkey health spa built for them higher up the mountain. Here they happily dive-bomb and wallow in the steaming water for hours. The youngsters even make snow-balls around the pool.
