2. New world primates

3. New World monkeys are limited to tropical
forest environments of southern Mexico,
Central, and South America. All of these
monkeys are predominantly arboreal and
mostly herbivorous. They eat leaves, fruits,
nuts, gums, and occasional small prey such as
insects. Today, there are at least 53 species
commonly divided into two families—Cebidae
(Squirrel monkeys,spider monkeys).
Callitricidae.(marmosets).

12. Old world primates

13. The Old World monkeys occupy a wide variety of
environments in South and East Asia, the Middle
East, Africa, and even Gibraltar at the southern tip of
Spain. Some species inhabit tropical forests, while
others live on arid grasslands and even mountainous
areas with heavy winter snows.
There are at least 78 species of Old World monkeys
in two subfamilies---the Cercopithecinae and the
Colobinae. Monkeys in both groups are relatively
large, being about the size of small to medium-size
dogs.
