The spectacled langur is known by two very obvious features. One is its long tail that hangs straight down when it sits in the treetops. The other distinguishing feature, which is implied by the name, is white patches of skin that encircle the eyes and mouth. The white circles around the eyes resemble spectacles, hence the name spectacled langur.
Langurs are very agile.
They swing, hang, and leap through the branches of trees high above the ground. After breeding is successful, the female will be pregnant with one baby for about five to six months. Occasionally twins may be born. Oddly enough when the baby is born, it is covered with bright orangish red fur. The baby spends the first year of its life clinging tightly to its mother.
