Quick answer
Proboscis Monkeys (Nasalis larvatus) are listed in our guides as Endangered. That IUCN-style label describes global extinction risk and can differ from national lists — habitat loss and human pressure still decide local survival.
Key takeaway
Proboscis Monkeys (Nasalis larvatus) are listed in our guides as Endangered. That IUCN-style label describes global extinction risk and can differ from national lists — habitat loss and human pressure still decide local survival.
Proboscis Monkey conservation status
Proboscis Monkey (Nasalis larvatus) is recorded here as Endangered. Global categories summarise extinction risk; regional populations can be safer or worse than the headline label.
Threats facing proboscis monkeys
Habitat loss around Borneo mangroves, peat swamp, and riverine forest, hunting or persecution, climate pressure, and conflict with people are common drivers. Exact ranking of threats varies by region.
Outlook for Proboscis Monkey populations
Where monitoring exists, trends track protected-area quality and enforcement. Fragmented groups need corridors and genetic exchange to avoid local extinction.
What actually helps
Support verified conservation programmes, cut demand for illegal wildlife products, and protect habitat. Tourism helps only when operators follow ethical wildlife standards.
Physical traits and behaviour
Proboscis Monkeys typically reach about 0.75 m in length and 20 kg in weight, with top speeds near 24 km/h. Borneo's big-nosed swimmer. Daily activity, social structure, and seasonal movements reflect pressures in their native environment.
Diet and ecological role
Proboscis Monkeys feed on herbivore — leaves, unripe fruit, seeds, and flowers. Foraging shifts with season and local abundance. As mammals, they influence food webs — controlling prey, dispersing seeds, or shaping habitat through feeding and movement.
