The Purple-faced langur or Semnopithecus vetulus also known as the Purple-faced leaf monkey, is a species of Old World monkey that is endemic to Sri Lanka. The animal is a long-tailed arboreal species, identified by a mostly brown appearance, dark face (with paler lower face) and a very shy nature.
Purple-faced langur or Semnopithecus vetulus males are usually larger than females. Males measure 19.7 to 26.4 in. in head-body length with a tail of 26.4 to 33.5 in. Females possess a head-body length 17.6 to 23.6 in. and tail length of 23.2 to 32.3 in. The fur may generally vary from blackish to grayish.
The Purple-faced langur or Semnopithecus vetulus tends to have whitish to gray short ‘trousers’ rounded off by purplish-black faces with white sideburns.
Part of the back is covered with whitish fur, and tail is also furred with black and white mixed colors. The feet and hands are also purplish-black in color.
The Purple-faced langur or Semnopithecus vetulus is mostly folivorous, but will also feed on fruits, flowers, and seeds. While they normally avoid human habitations, fruit such as jak, rambutan, banana, and mango may contribute up to 50 percent of their diet in cultivated areas. In the wild, food such as the fruits of Dimocarpus longan and Drypetes sepiaria are eaten.
Purple-faced langur or Semnopithecus vetulus digestion is adapted to derive the majority of required nutrients and energy from complex carbohydrates found in leaves, with the help of specialized stomach bacteria.
Loud calls are often used to distinguish between individual purple-faced langurs. The elements of a call fall into three categories: harsh barks, whoops, and residuals.
Individuals can be differentiated by the number of phrases and residuals within a call. Calls occur more often in the morning mostly stimulated by neighboring groups and territorial battles.
