Love knows no bounds
Langurs are polygamous and live in social groups of around 7 members with 1 or 2 adult males in the group. The male maintains close relationships with all of his females. A female can look after the offspring of other females in the group, but only the mother feeds her young. Young langurs become independent at 1 year old and the adolescent males then leave the group.

Protected by the law
Their populations are falling because of human activities that are destroying their habitat. But it's also a species that suffers from illegal wildlife trade. Laws protecting the Javan langur were adopted in 1999, and today we can find them in 3 Indonesian national parks.
