The Hatinh langur[1] (Trachypithecus hatinhensis) is a critically endangered Old World monkey found in the limestone forests of Vietnam, particularly in Quảng Bình province.
- These graceful langurs are long, slender, and muscular, with glossy black fur covering their entire body and tail.
- The band of white fur that sticks out from their cheeks looks like a delicate brushstroke, giving them a distinguished look.
- It extends above and behind the rounded ears to the nape of the neck. Their oval, smooth face is crowned by a spiky strand of hair.
- Their eyes are brown, and their nostrils are slanted downwards.
- They have 5 digits on their feet and hands, which makes them very dexterous.
