François’ langur

François' langur (Trachypithecus francoisi) is a species of Asian monkey belonging to the subfamily Colobinae. These monkeys are known for their long tails, slender bodies, and specialized digestive systems adapted for a diet of leaves, fruit, and vegetation.1

François' langurs are found in the limestone regions of northern Vietnam, Laos, and parts of southeastern China. They are part of a group of langurs often called brow-ridged langurs, characterized by their distinctive facial features. Like other langurs, they are social animals, often living in groups. Sadly, several langur species, including François' langur, are considered endangered.1
