Golden Snub-nosed Monkey vs Proboscis Monkey: Asian Monkey Species Comparison
These two endangered Asian monkeys are both colobines, a group with chambered stomachs that help digest leaves. The Golden Snub-nosed Monkey, Rhinopithecus roxellana, lives in cold mountain forests of central China and wears thick golden fur around a blue face. The Proboscis Monkey, Nasalis larvatus, lives near Borneo’s warm rivers and mangroves. Adult males carry a huge hanging nose, and the species is one of the strongest swimmers among primates.
About Golden Snub-nosed Monkey
- Type Living
- Diet Mostly herbivore; eats lichens, leaves, buds, bark, fruit, seeds and flowers, with foods changing by season
- Group Asian leaf monkey in the Old World monkey family Cercopithecidae (Rhinopithecus roxellana)
- Known for A pale blue face, tiny upturned nose, rich golden-orange coat and very long cold-weather fur on adult males
- Special skill Survives snowy mountain winters with dense fur and changes its menu when fruit and young leaves become scarce
About Proboscis Monkey
- Type Living
- Diet Mostly herbivore; eats leaves, seeds, flowers and unripe fruit, plus occasional insects and other small animal foods
- Group Bornean leaf monkey in the Old World monkey family Cercopithecidae (Nasalis larvatus)
- Known for The adult male’s enormous drooping nose, reddish coat, pale belly, gray limbs and large chambered stomach
- Special skill Leaps into rivers, swims strongly with partly webbed toes and can travel about 20 m completely underwater
Golden Snub-nosed Monkey vs Proboscis Monkey: Quick Answer
A male Golden Snub-nosed Monkey is usually about 58–68 cm from head to body and averages roughly 18–20 kg in some estimates. Its tiny upturned nose and thick coat suit a cold mountain home. A male Proboscis Monkey is about 66–76 cm long and commonly 16–22.5 kg, with a large belly and huge drooping nose. It lives near tropical water and is the clear swimming specialist.

How Are Golden Snub-nosed and Proboscis Monkeys Alike?
- Both are Asian Old World monkeys in the leaf-eating colobine branch.
- Both have long tails, grasping hands and feet, and spend much of their time in trees.
- Both use chambered stomachs and helpful gut microbes to break down tough leaves.
- Both form one-male family groups that can gather with other groups into larger bands.
- Both are listed as Endangered because human activity has reduced and divided their forest homes.
How Are Golden Snub-nosed and Proboscis Monkeys Different?
- The Golden Snub-nosed Monkey lives in cold Chinese mountains; the Proboscis Monkey lives in hot Bornean wetlands.
- The golden monkey has a tiny upturned nose, while an adult male proboscis monkey has a huge drooping nose.
- Golden monkeys grow dense gold-and-brown fur; proboscis monkeys have reddish backs, gray limbs and pale bellies.
- Golden monkeys can gather in bands of hundreds, while proboscis bands are usually much smaller.
- Proboscis monkeys are expert river swimmers with partly webbed toes; golden monkeys are mountain forest specialists.
Golden Snub-nosed vs Proboscis Monkey Showdown
- Size – Proboscis Monkey: Adult males are often longer and can be heavier, although size ranges overlap and golden males are also large.
- Speed – Tie: Both leap and climb well, but no reliable matched race makes one a fair overall winner.
- Strength – Proboscis Monkey: Its longer, often heavier male body gives it the edge in total muscle and mass.
- Stealth – Tie: Golden fur breaks up a monkey’s shape among mountain branches, while reddish-brown fur blends into wet tropical forest.
- Social – Golden Snub-nosed Monkey: Its many family and bachelor units can coordinate inside extraordinary bands containing hundreds of monkeys.
- Swimming – Proboscis Monkey: Partly webbed toes and documented underwater swims make this riverside species the clear champion.
- Weirdest – Proboscis Monkey: A huge sound-shaping nose, pot belly and partly webbed toes create a combination found in no other monkey.
Fun Golden Snub-nosed Monkey vs Proboscis Monkey Facts
A Monkey Built for Snow
Golden Snub-nosed Monkeys live higher and tolerate colder average temperatures than almost any other nonhuman primate.
Hundreds in One Society
Many small golden monkey family units and bachelor units may travel together in one huge multilevel band.
A Nose That Changes Calls
The adult male Proboscis Monkey’s large nose helps make his calls louder and lower, and it may advertise his quality to other monkeys.
An Underwater Primate
Proboscis Monkeys have been recorded swimming about 20 m completely beneath the surface.
Leaf-Digestion Chambers
Both species have enlarged, chambered stomachs where microbes help turn tough plant material into usable energy.

Golden Snub-nosed Monkey vs Proboscis Monkey FAQ
Are Golden Snub-nosed and Proboscis Monkeys Closely Related?
They are different genera, but both belong to the colobine group of Old World monkeys, whose members are adapted for eating leaves.
Which Monkey Is Bigger?
Male size ranges overlap, but Proboscis Monkeys are generally longer and large males can be heavier. Female sizes also differ between populations.
Why Does the Golden Snub-nosed Monkey Have Almost No Nose?
Its nasal bones and soft tissues form forward-facing nostrils without a projecting nose. Scientists do not know one simple reason for this shape.
Why Is the Proboscis Monkey’s Nose So Large?
In adult males, the nose helps deepen and amplify calls. Studies also suggest females notice larger noses and other males respond to them.
Can Both Monkeys Swim?
Both can enter water, but Proboscis Monkeys are the specialists. They leap into rivers, have partly webbed toes and can swim below the surface.
