Javan langur -- The Monkey With a Mane

The Javan langur is sexually mature at age 3-4. The females give birth to one offspring every 18-21 months. Gestation is 170-200 days, and the infants are born able to see and move around. The infants become independent at 1 year old and the adolescent males then leave the group or troop. They live in all-male groups until old enough and strong enough to become an alpha male. Each troop has one, or sometimes two males, and both of the males will both mate with the females in the troop. The Alpha males are also the protectors of the groups. Langurs are territorial and give out warning “hoots” to warn other troops. Males in the all-male troops rarely fight amongst themselves, whereas, the females tend to be more aggressive to other females within their troop. However, females care for all infants in the troop, which is known as allomothering. Langurs breed all year round so there are always infants in a troop. Troops usually have 7- 23 members.
The Javan langur is listed as “Vulnerable” on the IUCN Red List of Endangered Species. Humans are the only known predator at this time. Langurs are illegally hunted for food or captured alive for pets. The habitat of the Javan langurs is being destroyed by deforestation for human habitats, agriculture, and illegal logging. Fortunately, some of these adorable monkeys live on protected reserves.
