Proboscis Monkey
Nasalis larvatusAlso known as Long-nosed Monkey, Bekantan
Proboscis monkeys are highly specialized, tree-dwelling primates famous for the male's massive, pendulous nose, which amplifies vocalizations to attract mates and intimidate rivals. These excellent swimmers possess partially webbed feet and a large, multi-chambered stomach designed to ferment tough mangrove leaves. Living in highly organized harem groups, they leap dramatically from high branches into rivers to cross waterways.

Capable of a powerful bite if cornered or threatened; observe quietly from a safe distance.
Endangered due to severe habitat fragmentation from logging, agriculture, and coastal development.
Never feed or attempt to approach them; support local eco-tourism that protects mangrove habitats.- Boat tours: View them from a boat along riverbanks in the early morning or late afternoon.
- Keep distance: Maintain at least 15 meters to avoid causing stress or defensive behavior.
- Listen closely: Listen for the loud, nasal honks of the dominant males echoing through the canopy.
