What is the most harmless monkey?

It's impossible to say definitively which monkey is the "most harmless" because:

* "Harmless" is subjective: What one person considers harmless another may not.

* Behavior depends on context: A monkey's behavior can vary depending on its environment, social group, and individual temperament.

* Monkeys are wild animals: Even the most "harmless" monkey can bite or scratch if threatened or provoked.

However, some monkeys are generally considered more docile and less likely to be aggressive towards humans than others. These include:

* Capuchin monkeys: Known for their intelligence and playful nature, they are often used in research and entertainment.

* Squirrel monkeys: Small and agile, these monkeys are relatively friendly and often kept as pets.

* Marmosets and tamarins: These tiny monkeys are known for their gentle nature and are popular pets.

It's important to remember that even these "harmless" monkeys should not be treated as pets. They require specialized care and can be difficult to handle. If you're interested in learning more about monkeys, it's best to visit a zoo or sanctuary where they are cared for by professionals.
