Do you find monkeys, like the patas monkey, interesting? Then here we have all the information you need on the white-headed langurs.

The white-headed langur (Trachypithecus poliocephalus) is an Endangered species of langur monkey that is endemic to Vietnam. They are also known as a Cat Ba langur and a golden-headed langur. These langurs can only be found in the Cat Ba Island of Ha Long Bay.

They live in groups made up of families and bachelor langurs. Their population has gone down since the last few decades, which has led to fewer numbers of male and female langurs, and that led to a low number in reproduction. The female now gives birth to a single infant in a span of two to three years.

However, their population numbers were never that high, to begin with. They have distinctive yellowish-gray fur covering their head that extends to their chin.
