Red-Shanked Douc is known as one of the most colorful primates on the planet. It has a vibrant orangey-yellow face and reddish-brown neck and legs. These are quite rare in the community of primates.
This species is also conspicuous with white whiskers and forearms, creating a striking contrast with its black and gray fur over the body. Some people think that they jump out from books but they do exist in the wild.
