The real Proboscis monkey
- Scientific name

- Japanese name
- テングザル
- Group
- Land mammals
- Class
- Mammalia
- Order
- Primates
- Family
- Cercopithecidae
- Genus
- Nasalis
This monkey lives on the island of Borneo and nowhere else, in mangrove forests by the sea and swampy forests along rivers.
An adult male's big nose helps his calls resonate, and while eating he sometimes pushes his nose up with one hand.
It has webbing between its fingers and toes and is a good swimmer; it may even leap from the trees into the water.
How the Proboscis monkey lives
It is active during the day, especially from late afternoon until dark. It eats foods including young leaves, fruit and seeds. In the evening, several groups gather to sleep.
