Javan langur groups normally consist of one male and 5-6 females plus their offspring. The other males form bachelor groups. Langur means ‘having a long tail’ in Hindi.
Javan langurs have two distinct colours; one being glossy black, the rarer form a deep orange. At birth all infants are a bright apricot colour to ensure they are the centre of the group’s attention. Female langurs share infant carrying duties. Since 1980 we have celebrated well over 100 Javan langur births.

Javan langurs are primarily leaf eaters but also eat small amounts of seeds, fruits, flower, bark and fungi. To get the nutrition from the leaves, they have a four chambered stomach and enlarged salivary glands to aid digestion.
Javan langurs are vulnerable to extinction due to habitat loss, the illegal pet trade and hunting. Langurs are often kept as pets in Java and, due to their specialist diet, their owners do not know how to look after them. They are kept on their own in small cages or tied to a post. Working with government officials, The Aspinall Foundation rescues these langurs, rehabilitates them and reintroduces them back to protected areas of the wild. Langurs from Howletts and Port Lympne are also being released in the wild. In total 56 langurs have been reintroduced so far.
