“Langur”, was originated from a Hindu term, meaning “long-tailed”. They certainly own this name as their tail length ranges from 50-85 cm, longer than its body! This primate has another unique appearance. In its dark gray body fur, there are white-colored fur patches surrounding its eyes and mouth, like a pair of eyeglasses!

Baby dusky langurs are born with bright orange fur with a slightly pinkish face. During the early 6 months, the color of the fur changes from orange to grey/brownish.
