Monkey

A monkey is a common name for many species of tailed primates, especially those in the New World monkeys and Old World monkeys.

Updated July 27, 20261 min readCited sources

A monkey is a common name for many species of tailed primates, especially those in the New World and Old World groups. The term is not a single scientific clade and is often used broadly for simian primates that are not apes.

What it is

Monkeys are small to medium-sized primates, typically distinguished from apes by the presence of a tail. They are divided into two major groups: Old World monkeys (Africa and Asia) and New World monkeys (the Americas). About 200 species exist, and most are arboreal, though some, like baboons, live on the ground.

Key details

Monkeys are generally social, intelligent, and omnivorous, eating fruit, insects, and other small foods. They have grasping hands, forward-facing eyes, and are adapted for climbing or leaping. Their habitats range from rainforest canopies to open woodlands, mainly in tropical and subtropical regions.

Why it matters

Though not native to Canada, monkeys are relevant through zoos, conservation, and biomedical research. Understanding their classification helps clarify the difference between monkeys and apes, a common point of confusion in everyday language.

In short

  • Monkeys are tailed primates, not apes.
  • They are divided into Old World and New World groups.
  • About 200 species live in tropical regions worldwide.
  • Most are social, omnivorous, and arboreal.
Canadian angle

Monkeys are not native to Canada, but they are relevant to Canadian readers through zoological education, zoo collections, conservation issues, and their role in biomedical and behavioural research.
