The Javan Langur is a species of primate found primarily on the island of Java in Indonesia. Known scientifically as *Trachypithecus auratus*, these monkeys have a distinctive appearance with long limbs, a slender body, and a coat that varies from black to golden-yellow. They primarily inhabit tropical rainforests and are known for their social behavior, often living in groups. These langurs are herbivorous, feeding mainly on leaves, fruits, and flowers. They play a crucial role in their ecosystem by aiding in seed dispersal. Unfortunately, the Javan Langur faces threats from habitat loss and hunting, leading to a decline in their population. Conservation efforts are essential to protect this unique species.
