* Agility: Woolly monkeys are arboreal, meaning they live in trees. They are excellent climbers and can move through the trees quickly and easily. This agility makes it difficult for predators to catch them.
* Social structure: Woolly monkeys live in groups of up to 20 individuals. These groups are typically made up of related females and their offspring, as well as a few adult males. The monkeys cooperate to defend their territory from other groups of woolly monkeys and from predators. They will often mob predators, making noise and throwing sticks and branches. This mobbing behavior can deter predators and give the woolly monkeys time to escape.
* Camouflage: Woolly monkeys have thick, shaggy fur that helps them camouflage themselves in the trees. This fur also helps to protect them from the cold weather in their mountain habitat.
* Warning signals: Woolly monkeys use vocalizations and body language to communicate with each other and to warn of predators. They have a variety of calls that they use to alert the group to danger. They also use body language, such as piloerection (raising the fur on their backs) and teeth-baring, to warn off predators.
* Fleeing: Woolly monkeys are more active during the day due to the protection they get from the sunlight. They also try to stay away from areas where predators are known to frequent.
