Proboscis monkeys are endemic to Borneo. They are usually found in mangrove, nipah and lowland forests along rivers' edges. The adult male weighs approx. 20 to 25 kg and has a long pendulous nose, big bloated belly and a long thick tail. Female, on the other hand, weighs 10 to 15 kg and features a small pointed nose (above a young male).
In the evening, proboscis monkeys find tall tree branches by the river side, which they will hug to sleep upon night fall.
