Category: Environment, Ecology and Biodiversity

UPSC Notes

Hoolock gibbons are arboreal primates native to South and Southeast Asia. They are members of the ape family and are notable for their long arms and specialised movement through forest canopies.

Distribution and habitat

  • Found in parts of Northeast India and neighbouring regions of South and Southeast Asia.

  • Depend heavily on tropical and subtropical forests.

  • Move between branches through a form of locomotion called brachiation.

  • Feed on fruits, leaves, flowers and other plant material, with diet varying by species and location.

Major threats

  • Habitat loss and fragmentation.

  • Infrastructure development and forest degradation.

  • Hunting and other human pressures.

  • Isolation of small populations.

Key Pointers for UPSC

  • Gibbons are apes, not monkeys.

  • Hoolock gibbons are the only apes native to India.

  • Northeast India is important for their conservation.

  • Forest connectivity is essential for maintaining viable populations.

  • The western and eastern hoolock gibbons are distinct species; conservation status should be checked against the current IUCN assessment and applicable Indian wildlife legislation.
