The Bornean orang utan (Pongo pygmaeus) is a critically endangered species and a symbol of Malaysia’s rich biodiversity. Found primarily in the tropical rainforests of Borneo, this great ape is renowned for its intelligence, unique behavior, and vital role in forest ecology.
As we approach the Borneo Flora Festival 2025 in Labuan, it’s an opportune moment to delve into the fascinating world of the Bornean orangutan and understand why it deserves our admiration and protection.
What is the Bornean Orangutan?
The Bornean orangutan is one of three orangutan species, distinguished by its reddish-brown hair and remarkable arboreal lifestyle. Endemic to Borneo, it inhabits both lowland and montane rainforests, playing a crucial role in seed dispersal and maintaining forest health.
Specialities of the Bornean Orangutan
- Arboreal Adaptations: With long arms spanning up to 1.5 meters, they navigate the forest canopy with ease.
- Intelligence: Known for using tools, such as sticks to extract insects or leaves as umbrellas, showcasing advanced problem-solving skills.
- Diet: Primarily frugivorous, they consume over 400 types of food, including fruits, leaves, bark, and occasionally insects.

Differences Between Orangutan, Monkey & Chimpanzee
- Tail: Monkeys possess tails; orangutans and chimpanzees do not.
- Locomotion: Orangutans are primarily arboreal, while chimpanzees and many monkeys are more terrestrial.
- Social Structure: Chimpanzees are highly social, living in large groups; orangutans are more solitary.
- Intelligence: All exhibit intelligence, but orangutans are particularly noted for their problem-solving abilities.
Many people often confuse orangutans, monkeys, and chimpanzees because they all look somewhat similar and live in forests. However, these three animals are actually quite different. They all belong to the primate family, which includes humans too, but only some of them are considered great apes.
Let’s start with monkeys. Monkeys are usually smaller than the other two and have one clear feature that sets them apart—they have tails. Most monkeys are quick, love to jump from tree to tree, and live in large groups. Some examples include the capuchin monkey, the howler monkey, and the proboscis monkey. Monkeys can be found in many parts of the world, such as Asia, Africa, and South America. They are clever and energetic, but not as closely related to humans as apes are.
Next, we have the orangutan, which is a great ape. Orangutans are much larger than monkeys and have no tails. They have long, strong arms, reddish-orange hair, and live in the rainforests of Borneo and Sumatra in Southeast Asia. Orangutans are very smart and are known for using tools, such as sticks to get insects or honey. Unlike monkeys, orangutans usually live alone and prefer quiet forest life. They move slowly through the trees and spend most of their time up high in the branches.
Then there’s the chimpanzee, another great ape and the closest living relative to humans. Chimpanzees do not have tails either. They are found in African forests and are very social animals, living in large families called troops. Chimps are incredibly intelligent. They can use tools, play, show emotions, and even learn basic human sign language. They are curious and playful, and they often communicate using sounds, gestures, and facial expressions.
