New World monkeys
The New World monkeys
are the two families of primates
that are found in Central and South America, the Callitrichidae
. Both families differ from the Old World monkeys
and apes in having prehensile tails. Technically they are distinguished from Old World monkeys on the basis of the structure of the nose. Many are small, arboreal
, so our knowledge of them is less comprehensive than that of the more easily observed Old World monkeys. Unlike most Old World monkeys, many New World monkeys form monogamous
pair bonds, and show substantial paternal care of young.
