The spectacled langur, also known as the spectacled leaf monkey, is a species of primate found primarily in the forests of Southeast Asia, particularly in Malaysia and Borneo. They are easily recognizable by the distinctive white markings around their eyes, which resemble spectacles. These monkeys are arboreal, spending most of their time in trees, and are known for their strong limbs and long tails that help them navigate their forest habitat. Spectacled langurs are primarily herbivorous, feeding on leaves, fruits, and flowers. They live in small social groups, typically consisting of a few adults and their young. Their population is threatened by habitat loss due to deforestation and hunting, making conservation efforts essential for their survival.
