They sleep at the ends of branches, where it's hard for a large predator to get at them. They have a life span of about 20 years but in captivity they can live for 25 years.
The Hanuman Langur feed on leaves, fruit, buds and flowers. Their diet is highly seasonable. At times, they also supplement their diet with insects, tree bark and gum.
