Chimpanzee vs. Gorilla

What's the Difference?

Chimpanzees and gorillas are both highly intelligent primates, but they have distinct differences in their physical characteristics and behavior. Chimpanzees are smaller in size, with an average height of 3 to 5 feet and a weight of 70 to 130 pounds. They have longer arms and are known for their agility and ability to swing from trees. Gorillas, on the other hand, are much larger, with males reaching heights of up to 6 feet and weighing between 300 to 400 pounds. They have a more robust build and are primarily terrestrial, using their knuckles to walk. In terms of behavior, chimpanzees are more social and live in larger communities, while gorillas tend to live in smaller family groups. Chimpanzees are also known for their tool-making abilities and complex social interactions, while gorillas are known for their gentle nature and herbivorous diet.

Further Detail


Chimpanzees and gorillas are two of the most fascinating and intelligent primates that inhabit our planet. While they share some similarities, they also possess distinct attributes that set them apart. In this article, we will explore the characteristics of both chimpanzees and gorillas, highlighting their physical features, social behavior, habitat, diet, and conservation status.

Physical Features

Chimpanzees and gorillas exhibit noticeable differences in their physical appearance. Chimpanzees are generally smaller, with males weighing between 90 to 120 pounds and standing around 3 to 5 feet tall. They have long arms, short legs, and a slender body covered in coarse black hair. In contrast, gorillas are much larger, with males weighing up to 400 pounds and standing around 5 to 6 feet tall when upright. They have a robust build, long arms, and a broad chest covered in dark brown or black hair.

Both species have opposable thumbs and big toes, allowing them to grasp objects and climb trees proficiently. However, gorillas possess a more pronounced sagittal crest on their skull, which provides attachment points for their powerful jaw muscles. This feature is absent in chimpanzees.

Social Behavior

Chimpanzees and gorillas exhibit distinct social behaviors. Chimpanzees are highly social animals, living in communities known as troops or communities. These troops can consist of 15 to 120 individuals, led by a dominant alpha male. Within the troop, chimpanzees form complex social hierarchies, engage in cooperative hunting, and display a wide range of behaviors such as tool use, grooming, and communication through vocalizations and gestures.

Gorillas, on the other hand, live in smaller groups known as troops or bands. A typical gorilla troop consists of a dominant silverback male, several adult females, and their offspring. Gorillas are generally peaceful and non-aggressive, with the silverback responsible for protecting the group. They communicate through vocalizations, body postures, and facial expressions, emphasizing their social bonds and maintaining group cohesion.


Chimpanzees and gorillas inhabit different regions and have distinct habitat preferences. Chimpanzees are found in the forests and woodlands of Central and West Africa, including countries like Uganda, Tanzania, and the Democratic Republic of Congo. They thrive in diverse habitats, ranging from rainforests to savannah woodlands, and are adaptable to various environmental conditions.

Gorillas, on the other hand, are primarily found in the dense forests of Central and East Africa, including countries like Rwanda, Uganda, and the Democratic Republic of Congo. They are specifically adapted to live in montane and lowland rainforests, where they can find an abundance of food and suitable shelter.


Chimpanzees and gorillas have different dietary preferences, although they both consume primarily plant-based diets. Chimpanzees are omnivorous, meaning they eat a variety of foods including fruits, leaves, seeds, flowers, insects, and occasionally small mammals. They are known for their ability to use tools, such as sticks or rocks, to extract termites from their mounds or crack open nuts.

Gorillas, on the other hand, are herbivores and mainly feed on leaves, stems, shoots, fruits, and bark. They have a specialized digestive system that allows them to efficiently process fibrous vegetation. Gorillas spend a significant portion of their day foraging for food, as their large size requires a substantial amount of plant matter to sustain their energy needs.

Conservation Status

Both chimpanzees and gorillas face significant threats to their survival, primarily due to habitat loss, poaching, and disease. Chimpanzees are listed as endangered by the International Union for Conservation of Nature (IUCN), with their populations declining rapidly. The destruction of their forest habitats, hunting for bushmeat, and the illegal pet trade are major factors contributing to their decline.

Gorillas, on the other hand, are divided into two species: the eastern gorilla and the western gorilla. The eastern gorilla is listed as critically endangered, while the western gorilla is listed as endangered. Habitat destruction, poaching, and the transmission of diseases from humans are the primary threats to their survival.


In conclusion, while chimpanzees and gorillas are both remarkable primates, they possess distinct attributes that make them unique. Chimpanzees are smaller, highly social, adaptable, and exhibit omnivorous feeding habits. Gorillas, on the other hand, are larger, peaceful, specialized herbivores, and inhabit specific forest habitats. Both species face significant conservation challenges, emphasizing the need for increased efforts to protect and preserve their populations and habitats.
