When you think about apes, you might picture playful gorillas or swinging gibbons. The four kinds of apes are gibbons, orangutans, gorillas, and chimpanzees. Each type has its own unique traits and behaviors that make them fascinating to learn about.
They belong to two main groups: lesser apes, which include gibbons, and great apes, which consist of orangutans, gorillas, and chimpanzees.
As primates, these apes share many similarities, but they also face significant challenges. Habitat loss and poaching have put many ape species at risk, making conservation efforts critical.
Understanding the differences between these types of apes can help you appreciate the importance of protecting their environments and ensuring their survival for future generations.
By exploring their habitats, social structures, and conservation status, you’ll discover why these remarkable creatures need your attention. Learning about the four kinds of apes can inspire you to support efforts that protect them and the ecosystems they inhabit.
Classifying Apes

When you think about apes, it’s helpful to understand how they’re classified. Taxonomy is the system used to group living things, and it reveals a lot about their relationships. You’ll also learn about the differences between great apes and lesser apes.
Taxonomy of Apes
Apes belong to two main families in the primate order: Hominidae and Hylobatidae. The Hominidae family includes great apes like gorillas, orangutans, chimpanzees, bonobos, and humans.
The Hylobatidae family consists of lesser apes, which mostly include gibbons. These classifications show how closely related different types of apes are.
In total, there are about 8 living species of great apes and around 14 species of gibbons. Each group has unique traits and behaviors. For instance, gorillas are known for their size, while gibbons are recognized for their incredible agility in trees.
Great Apes Versus Lesser Apes
Great apes and lesser apes differ in several ways. Great apes, such as gorillas, orangutans, chimpanzees, and bonobos, are larger and often exhibit more complex social behaviors.
For example, chimpanzees and bonobos live in intricate social groups and show problem-solving skills. They are known to use tools, which highlights their intelligence.
On the other hand, lesser apes like gibbons are generally smaller, have longer arms, and are known for their swinging locomotion, called brachiation. They primarily live in trees and are known for their vocal calls that often carry over long distances. Understanding these differences helps you appreciate the diversity within the ape family.
Great Apes

Great apes are fascinating creatures that belong to the family Hominidae. They include four main species: gorillas, orangutans, chimpanzees, and bonobos. Each species has unique characteristics and habitats, making them intriguing to study.
Gorillas
Gorillas are the largest primates and are divided into two main groups: eastern and western gorillas. The eastern gorilla includes the Mountain gorilla and the Eastern lowland gorilla, while the western gorilla is made up of the Western lowland gorilla and the Cross River gorilla. These gentle giants can weigh up to 200 kg and stand around 1.8 m tall.
Gorillas live in family groups, called troops, usually led by a dominant male. They primarily eat leaves, stems, and fruits. Gorillas show strong sexual dimorphism, where males are significantly larger than females.
Their natural habitats are typically lush forests in Africa, where they move primarily on the ground but can climb trees when needed.
Orangutans
Orangutans are known for their striking red hair and intelligent behavior. There are three species: the Bornean orangutan, Sumatran orangutan, and Tapanuli orangutan. They are unique among great apes for their largely arboreal lifestyle, meaning they spend most of their time in trees.
Orangutans are solitary creatures, often living alone or with their young. They primarily eat fruit, leaves, and other plant material. Their long arms and flexible bodies help them move through the treetops.
Sadly, orangutan populations are declining due to habitat loss caused by logging and palm oil plantations, putting these incredible animals at risk.
Chimpanzees and Bonobos
Chimpanzees and bonobos are closely related and share about 98% of their DNA with humans. The common chimpanzee is found throughout Africa, while the bonobo is mostly located in the Democratic Republic of the Congo.
Both species live in social groups, often called communities. They display complex social behaviors and communicate through vocalizations and gestures.
Chimpanzees show sexual dichromatism, where males and females can be distinguished by color, though not as strongly as in some other species. Their diet consists mainly of fruits, leaves, and insects. They are known for using tools, demonstrating their remarkable intelligence.
While chimpanzee populations face threats from hunting and habitat loss, bonobos are somewhat protected due to their restricted range.
Lesser Apes

Lesser apes are fascinating creatures known for their agility and social behavior. They mainly include gibbons and siamangs, both found in the lush forests of Southeast Asia. These primates face challenges in their natural habitats, making understanding their diversity and behavior important for their conservation.
Gibbon Diversity
Gibbons are often referred to as the “lesser apes.” There are several species among them, including the lar gibbon, agile gibbon, and the black-crested gibbon. Each species has unique characteristics.
For instance, the siamang gibbon is larger and known for its throat pouch, which it uses for calling.
You’ll also find the western hoolock gibbon and the eastern hoolock gibbon in different regions. The pileated gibbon is notable for its striking appearance, while Kloss’s gibbon and the Bornean white-bearded gibbon showcase different colors and features.
Gibbons usually have opposable thumbs that help them grip branches while swinging through their tree-top habitats. Their adaptations allow them to thrive in the arboreal environment.
Behavior and Lifestyle of Gibbons
Gibbons are known for their playful and social nature. They often live in family groups and communicate using loud calls. This behavior is a way to establish territory and connect with others in their group.
Their diet mainly consists of fruits, leaves, and flowers. They use their powerful limbs for movement through the trees. Gibbons swing from branch to branch with ease.
Despite their adaptability, gibbons face significant threats from habitat destruction and hunting. Conservation efforts are crucial in protecting these amazing apes. Efforts focus on preserving their environments and raising awareness about their importance.
