Semnopithecus entellus (Hanuman langur)

The Hanuman langur (Semnopithecus entellus) is a large Old World monkey found across the Indian subcontinent, ranging from the Himalayan foothills to the southern plateaus. Females typically give birth to a single infant after a gestation period of about seven months, and newborns remain closely dependent on their mothers for several months. In the East Deccan moist deciduous forests of central India, langurs live in multi-female troops that navigate the canopy and ground in search of leaves, seeds, and fruit. This species is sacred in Hindu tradition and is often called the gray or common langur across its range. The mother-infant bond is critical during the first weeks of life, as the newborn develops the strength and coordination needed to climb and forage independently.
