Baboons
have complex social structures with anywhere from 8 to 200 individuals
per troop. They use at least 10 different vocalizations to communicate.
When traveling as a group, males will lead; females and young stay
safe in the middle and less dominant males bring up the rear. Young
chimps learn to create tools from objects in their environment by
watching others; they use sticks to extract termites to eat and crumple
leaves to soak up water to drink. |

Just
like people, mother chimpanzees often develop lifelong relationships
with their offspring. |

Lemurs
get their name from the Ancient Roman belief that they were ghosts
or spirits. They were mistaken for specters because of their nocturnal,
stealth habits. |

Lemurs
rely on their sense of smell as a way of communicating with other
animals. They have special scent glands on their wrists and bottoms
that leave scent trails on branches to mark their territories. |

The
intimidating chest-beating charge of a male gorilla is usually a bluff
to scare off intruders while the rest of his band disappears into
the forest. However, it is also used in play as well. |

Wild
gorillas are difficult to study because they are shy, secretive inhabitants
of densely vegetated tropical forests. |

"Marmoset"
is derived from the French "marmouset" which means, loosely,
shrimp or dwarf. An apt name, considering they are the smallest of
the true monkeys (the lightest of the true monkeys is the pygmy marmoset).

These
monkeys use their specialized claws to establish a firm grip on tree
trunks and gnaw little holes in the bark with their lower incisors
and canines. This causes the tree to produce more sap, which is used
to seal injuries to the bark. This tree sap is a valuable source of
carbohydrates and minerals. |

By following
wild chimps through the forests, scientists discovered that chimps
use medicinal plants to treat themselves for illness and injury. Scientists
have isolated an anti-tumor agent in one such plant! |

The
spider monkey's prehensile tail acts as an extra limb. The tail has
a hairless patch on the tip that is used for grip. This hairless patch
is unique in its markings, just like the human fingerprint. |

A female
spider monkey's clitoris is very protuberant and can be mistaken for
a penis. It acts as a reservoir for urine. The male is able to smell
when a female is in estrus. |

The
Old World monkeys of the subfamily Colobinae have a specially adapted
stomach that is sacculated and supports bacterial colonies. These
bacteria make it possible for digestion of cellulose in their diet
of leaves, unripe fruit, and seeds. |

The
differences between monkeys and apes are easy to see once you know
what to look for. Apes do not have a tail and are generally larger
than most other primates. They have a more upright body posture as
well. Apes rely more on vision than on smell and have a short broad
nose rather than a snout, as Old World monkeys do. Apes have a larger
brain relative to the body size than other primates do. |

Old
World monkeys are generally from Africa and Asia while New World monkeys
are from the Americas. In Old World monkeys, the nostrils face downward
and are narrow. New World monkeys have round nostrils facing to the
side. Old World primates are usually larger than New World's. Many
of the Old World monkeys are partly terrestrial. |
