New World versus Old World Monkeys

New World versus Old World Monkeys. What are the similarities and differences among them?

Some of the differences between these monkeys include:

Old world monkeys are believed to have been living in Africa, while the New world monkeys in South America.

New world monkeys thrive well in trees. They have wider nostrils, longer and sharp finger nails, and no passed buttocks.

Old world monkeys are larger, have flat fingernails, narrow downward pointing nostrils, hairless buttocks and thrive well in trees as well as on the land.

It is believed that, the old world monkeys only see two colors, that is, black and white. While the new world monkeys, just like humans, are able to see in colors.

Old World Monkeys

There are more than seventy eight species of the old world monkeys. Hence the largest private primates family. Including:

  • Baboons
  • Colobus
  • Guenons
  • Patas monkeys
  • Macaques
  • Proboscis monkeys
  • Langurs

They are native to Africa and Asia. Occupying habitats such as the savannas, shrublands, tropical rain forests, mountains, etc.

They are omnivores just like the other primates.

Unlike some of the greater apes, these mokeys have tails that are also able to hold on/ work almost like the third hand.

The daughters remain in the same troops as their mothers, while the son, move out to join other troops.

Whether old world or new world monkeys, they remain the most cheecky private species to interact with.

They have been observed to give care to their offsprings, grooming their partners, among other adorable behaviors. They operate almost like humans and will also imitate what we do stuff near them.

They are able to easily interact with humans, and learn a number of things.

Their populations are not yet worrying but we still need to protect their remaining habitat. As they need it.
