ACTIVITY 8 HAL 5

The Proboscis Monkey, scientifically known as Nasalis larvatus,

is an extraordinary primate native to the lush rainforests of Borneo,

particularly inhabiting the swampy areas near rivers and mangroves.

Renowned for its distinctive appearance, the Proboscis

Monkey is instantly recognizable by its prominent, pendulous nose,

which is more pronounced in males and often vibrantly colored.

With a stocky build and a reddish-brown fur covering its body, the

Proboscis Monkey typically sports a potbelly, giving it a comical

yet endearing presence. Its long, powerful limbs are adapted for a

semi-arboreal lifestyle, allowing it to navigate effortlessly through

the dense foliage and along the water’s edge.

The male Proboscis Monkey boasts an impressive nose that can grow up to 7 inches (17.8

centimeters) in length, serving as a resonating chamber to amplify its distinctive honking calls,

which echo through the forest canopy during territorial displays or social interactions. In contrast,

the female’s nose is much smaller and lacks the exaggerated size of the male’s.

Socially, Proboscis Monkeys form cohesive groups led by a dominant male, with several

females and their offspring forming the core of the troop. They are primarily herbivorous, feeding

on a diet consisting mainly of leaves, fruits, and seeds, although they have been observed

occasionally consuming insects and small invertebrates.

Due to habitat loss and hunting pressure, the Proboscis Monkey faces significant threats to its

survival. Conservation efforts aimed at preserving its natural habitat and raising awareness about

the importance of protecting this unique primate are crucial for ensuring its continued existence

in the wild.
