PRIMATE FACTS

Who and What are Primates?

Primates are mammals that typically have large highly developed brains, forward-facing color vision, flexible hands and feet with opposable thumbs, and fingernails. (Typically, but not always.)

Primates have slower developmental rates than other similarly sized mammals, reaching maturity later later in life, but with longer overall lifespans than many similarly-sized species.

With the exception of humans, who live throughout the globe, most primates live in tropical or subtropical regions. But don’t be fooled. Some also live in semi-deserts, alongside swamps, in cold mountainous regions, on rocky cliffs, or in cities.

The biological order “Primates” is divided into the following four classifications:

1. GREAT APES

bonobos, chimpanzees, gorillas, humans, and orangutans

2. SMALL APES

gibbons

3. MONKEYS

baboons, capuchin monkeys, colobus monkeys, drills, geladas, green monkeys, grivets, guenons, howler monkeys, langurs, lutungs, macaques, malbroucks, mandrills, mangabeys, marmosets, muriquis, night monkeys, patas monkeys, proboscis monkeys, sakis, snub-nosed monkeys, spider monkeys, squirrel monkeys, surilis, swamp monkeys, talapoins, tamarins, tantalus monkeys, titis, uakaris, vervets, and woolly monkeys

4. PROSIMIANS

 the oldest, most “primitive” order of primates includes angwantibos, galagos or bushbabies, lemurs, lorises, pottos, and, somewhat controversially, tarsiers

There are an estimated 522 primates species, plus an additional estimated 182 subspecies, with astounding diversity. 

70% of primate species and subspecies are threatened by extinction.

Where in the World Do Nonhuman Primates Live?

Nonhuman primates live in regions of Africa, Asia, and Latin America. Most (but not all) live in tropical climates along or near the equator. the map below provides reference points.

    • Great apes live in Africa and Asia
    • Small apes live only in Asia
    • Monkeys live naturally in Africa, Asia, and Latin America
      • Introduced* populations live in Gibraltar, on a few Caribbean islands, and in parts of the United States. These are not their native or natural homes
    • Prosimians live in Africa and Asia
WHAT IS AN INTRODUCED OR INVASIVE SPECIES?

An introduced species is a species living outside its native distributional range, which has arrived there by human activity, either deliberate or accidental. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are called invasive species. The impact of introduced species is highly variable. Some have a negative effect on a local ecosystem, while other introduced species may have no negative effect or only minor impact.

New World and Old World Monkeys

What's the Difference?

NEW WORLD MONKEYS
  • Found from southern Mexico to Central and South America, except in the highest mountains
  • More primitive than Old World monkeys
  • Their brains are considered less complex than those of Old World monkeys
  • Their thumbs, when present, are not opposable
  • Their nostrils are further apart and tend to point outward
  • Most have 36 teeth
  • They have slender bodies and limbs with long narrow hands
  • Most have a prehensile or partially prehensile tail
  • Include capuchin monkeys, howler monkeys, marmosets, muriquis, night monkeys, saki monkeys, spider monkeys, squirrel monkeys, tamarins, titis, woolly monkeys, and uakaris
  • No nonhuman apes are endemic to the New World
  • No prosimians are endemic to the New World 
OLD WORLD MONKEYS
  • Found throughout Africa, with the exception of the most arid deserts, and in southern Asia, with a few species as far north as Japan and northern China, 
  • Most, but not all, have opposable thumbs
  • Their tails are are never prehensile
  • Their nostrils are close together and tend to point downward
  • Many species have cheek pouches to hold food, and many have thick pads on their buttocks
  • They have 32 teeth
  • They are more closely related to the apes and, therefore, humans than they are to the New World monkeys
  • Include baboons, colobus monkeys, drills, geladas, green monkeys, grivets, guenons, kipunjis, langurs, leaf monkeys, macaques, malbroucks, mandrills, mangabeys, langurs, patas monkeys, proboscis monkeys, snub-nosed monkeys, surilis, swamp monkeys, talapoins, tantalus monkeys, and vervets
  • All apes are found in Old World regions of the world
  • Prosimians are also found in Old World regions
