What is a "langur"?

Langurs are primates found in Asia, known for their slender bodies, long tails, and diverse species. They typically have distinctive coloration with variations of black, gray, brown, or white fur. Langurs are arboreal, spending much of their time in trees, and are known for their acrobatic movements and leaping abilities. They live in complex social groups, often consisting of multiple males, females, and their offspring. Langurs are primarily herbivorous, feeding on leaves, fruits, and flowers, and play an important role in maintaining the balance of their ecosystems as seed dispersers.
