Despite their amusing appearance, proboscis monkeys are intelligent, social, and deserving of protection and appreciation.
📜 Origin and Natural Habitat
Proboscis monkeys (Nasalis larvatus) are found only on the island of Borneo. They live in mangrove forests, riverbanks, and swampy lowlands. These monkeys are excellent swimmers and often stay close to water.
Preferred habitats include:
- 🌳 Mangrove forests
- 🌊 Riverbanks and swamps
- 🌿 Coastal rainforests with thick tree canopies

- Weight: Males weigh about 44 pounds; females around 24 pounds
- Nose: Males have long, drooping noses; females have smaller ones
- Color: Reddish-brown fur with a light belly and gray limbs
Their large noses may help them attract mates and communicate with other monkeys.
