Proboscis Monkey also famous as the Long-nosed Monkey, the Proboscis Monkey is an Old World monkey. The monkey has a very large nose as well as a reddish brown color. Of course, its nose is the first thing to be noticed in its overall appearance, because it is simply distinct compared to any other monkey nose that you will see.
Its unique nose, generally measures up to seven inches in length, is only observed to be on the male monkeys. It is considered to have something to do with a breed ritual. The nose is not only an attraction because of its size, but it performs rare actions like swelling with blood when the monkey is angry or upset and also serves as a warning call.The Proboscis Monkey is found in Borneo’s mangrove forests, swamps, and even the plain riparian forests.
