Monkeys are some of the most intelligent and adaptable creatures on Earth, known for their playful antics, complex social structures, and vital roles in ecosystems. Found across Africa, Asia, and the Americas, these primates vary greatly in size, appearance, and behavior, from the tiny pygmy marmoset to the powerful mandrill. Their remarkable intelligence is evident in tool use and problem-solving, while their social bonds showcase the intricate dynamics of troop life. However, as forests shrink and threats grow, protecting monkeys becomes crucial—not just for their survival, but for the health of our shared planet.
