* Different social grooming practices: Monkeys, like many primates, engage in social grooming, which involves picking through each other's fur to remove parasites and dirt. This is a vital part of their social bonding and hygiene. They might use their fingers or teeth to do this, but not typically to pick noses.
* Nose structure: Monkey noses are often wet and more sensitive than human noses, making them less likely to be a target for picking.
* No perceived need: There's no evidence that monkeys find picking each other's noses beneficial or enjoyable. They likely rely on their grooming practices to keep their faces clean.
It's important to note: While we don't see monkeys picking each other's noses in the human sense, they may occasionally use their fingers or teeth to explore or clean around their nostrils. However, this is likely not a deliberate act of nose-picking.
If you're curious about monkey behavior, watching documentaries or visiting zoos can be a great way to learn more.
