How hairy is a monkey?

It's impossible to give a single answer to how hairy a monkey is because there are over 260 different species of monkeys, and they all have different amounts of hair. Some, like the spider monkey, have very little hair, while others, like the mandrill, have thick coats.

Here are some general points:

* Most monkeys have some hair: They are all primates, and primates tend to be hairy.

* Hair serves many purposes: It helps with insulation, camouflage, and communication (like displaying a threat or attracting a mate).

* Hairiness can vary by species and even within a species: Some monkeys have very thick fur, while others have thinner fur. This can also depend on the climate they live in.

* Hair can change with age: Young monkeys might have different hair patterns than adults.

If you're interested in the hairiness of a specific monkey, you'll need to research that particular species.
