Treetop Travellers
Also called East Javan langurs or ebony lutungs, these primates are diurnal and arboreal, living life high in the trees.
Active by day, they skilfully navigate the forest canopy, foraging and socialising among the branches.
Nature’s Plant Processors
Javan langurs have a primarily plant-based diet, feasting on leaves, fruits, flowers, and flower buds.
To efficiently digest tough plant material and ingest the most nutrition possible, they’ve evolved a multi-chambered stomach and large salivary glands, making them highly specialised plant processors.
Under Threat
Habitat loss, hunting, and the illegal pet trade endanger Javan langurs. Often caught and kept in small cages or tied up, these monkeys suffer from inadequate care, as their unique diet is difficult for owners to replicate. This makes conservation efforts crucial for their survival.
Together, We Protect Wildlife
Managed Species Programmes
We work with other zoos through Managed Species Programmes to help save threatened species.
This involves the transfer of animals between zoos for breeding so that genetically healthy animal populations can be maintained under human care.
Transfers are based on genetic compatibility, which prevents inbreeding and ensures their genetic integrity. Our Javan langurs are part of this effort.
