Entellus

Entellus is a genus of Old World monkeys belonging to the subfamily Colobinae. These monkeys are also commonly known as gray langurs or sacred langurs. They are found throughout the Indian subcontinent, including India, Nepal, Bhutan, Bangladesh, Pakistan, and Sri Lanka.

Gray langurs are primarily arboreal, inhabiting a variety of habitats including forests, open woodlands, and even urban areas. They are adaptable and can thrive in close proximity to human populations.

Physical Characteristics

Entellus monkeys are characterized by their grayish fur, black faces, and long tails. Their bodies are slender and agile, adapted for life in the trees. Adult males are typically larger than females.

Social Behavior

Gray langurs are social animals, living in troops that can range in size from a few individuals to over one hundred. These troops are often organized around a core of related females, with one or more adult males vying for dominance and mating opportunities. Social dynamics within the troop can be complex, involving hierarchies, alliances, and displays of dominance.

Diet

The diet of Entellus monkeys is primarily herbivorous, consisting mainly of leaves, fruits, flowers, and seeds. They may also supplement their diet with insects and other small invertebrates. Their specialized digestive systems allow them to efficiently extract nutrients from plant matter.

Conservation Status

The conservation status of different Entellus species varies. Some are classified as Least Concern, while others are considered Vulnerable or Endangered due to habitat loss, hunting, and human-wildlife conflict. Conservation efforts are focused on protecting their habitats and mitigating threats to their populations.
