Black-And-White Langur Characteristics

The black-and-white langur^[1] is a primate species in the Cercopithecidae family.

Like all members of the Presbytis genus, black-and-white langurs have tiny snouts and poorly developed eyebrow ridges.
In addition, they have extended frontal legs and relatively longer hind legs, consistent with their preferred mode of locomotion, jumping, and brachiating.
Black and white langurs are distinguished by the distinct patches of white fur on their thighs that contrast with their black fur.
Also, females have a patch of white fur close to their genitals.

Black-And-White Langur Facts

It was formerly thought to be a subspecies of the Presbytis melalophos (Black-crested Sumatran langur). Still, the genetic analysis indicated they were separate species.
The Black-and-white langur is endemic to the Indonesian island – Sumatra. It is listed as Data Deficient (DD) by the IUCN.
They live in groups consisting of one male and 5 to 7 females. Generally, groups with smaller home ranges are more territorial than groups with more extensive home ranges.
The scientific name of the species, Presbytis, is derived from a Greek word meaning “old woman, ” referring specifically to the withered features of the monkey.
Black and white langurs contribute to healthy ecosystems by dispersing the seeds of their plant-based diet via their feces.
