The spectacled leaf monkey, also known as the spectacled langur, is a species of primate found primarily in the tropical forests of Southeast Asia. They are easily recognizable by their distinctive facial markings, which resemble glasses or spectacles. These monkeys have a slender body, long limbs, and a predominantly black or dark brown fur coat, with lighter patches around their eyes. Spectacled leaf monkeys are herbivorous, primarily feeding on leaves, fruits, and flowers. They are social animals, often seen in small groups, and are known for their agile movements in the trees. Their habitat is threatened by deforestation and habitat loss, making conservation efforts essential for their survival.
