MONKEYS



MARMOSET
The family of monkeys divide into two groups. One is the Old World Monkeys which live in Africa and Asia and the other group is the New World monkeys which live in South America.
The New World monkeys are again divided into two families. One family is the Callitrichidae which are the tamarius and marmosets. The other family is the Cebidae which is the capuchin-like monkeys. The Old World monkeys are just one family and they are Cercopithecidae.
The South American monkeys live in the tree-tops. They are perfect climbers and quite a few have gripping tails which is used for climb.
The Old World monkeys living in Africa and Asia and they do not have gripping tails. Their habitat and way of life varies much.
The marmosets and tamarins live in the tropical forest. They are small and their movements are more like squirrels. The tamarins are slightly bigger than the marmosets. They are social animals and usual have a family of up to 15 with breeding pairs and their youngsters. Their diet is fruit and nuts but also eat spiders, snails, frogs and lizards. Adding to their diet are tree gum, sap and latex. Marmosets are experts on gum. They have large bevel-edged incisors with which they chisel into bark and when the trickle of gum starts, they lick it.

In the other family of the New World monkeys are 30 species. They are a big variety including the only monkeys with gripping tails.
