Monkeys are intelligent, social primates known for their playful nature and dexterity. They belong to the primate family, which includes apes and humans, and are found in diverse habitats such as rainforests, savannas, and mountains. With over 260 species, monkeys vary greatly in size, from the tiny pygmy marmoset to the larger mandrill. They are highly adaptable, using their strong limbs and prehensile tails to swing through trees with ease. Monkeys communicate through vocalizations, facial expressions, and body language, exhibiting complex social structures. Many species are omnivorous, feeding on fruits, leaves, insects, and small animals. Unfortunately, habitat loss and hunting threaten several monkey species, making conservation efforts essential. Their curiosity and intelligence make them fascinating subjects in scientific research and popular culture.
