It is common for many people to wonder about the precise relationship between gorillas and apes. This confusion often stems from the broad use of the term “ape” and the specific identity of “gorilla.” This article aims to clarify that relationship, explaining that gorillas are, in fact, a specific type of ape, and highlighting their unique characteristics within this diverse primate family.
Defining Apes
Apes belong to the superfamily Hominoidea, a group of primates that includes both great apes and lesser apes. A distinguishing feature shared by all apes is the absence of a tail, setting them apart from monkeys. Apes generally possess larger brains relative to their body size compared to other primates, contributing to their complex cognitive abilities and problem-solving skills.
Their skeletal structure allows for a more upright posture and a wide range of motion in their shoulder joints, facilitating arboreal locomotion like brachiation, which is swinging through trees. Apes also exhibit complex social behaviors, including intricate communication systems and diverse social structures. The great apes include gorillas, chimpanzees, bonobos, orangutans, and humans, while the lesser apes consist of gibbons.
Gorillas: A Distinct Member of the Ape Family
Gorillas are the largest of all primates, known for their immense size and strength. They exhibit a distinct form of locomotion called knuckle-walking, where they support their upper body weight on the backs of their curled fingers as they move on all fours. Their physical characteristics include broad chests, powerful arms, and a prominent sagittal crest on the skulls of males, which anchors large jaw muscles.
There are two main species of gorillas, the Eastern gorilla and the Western gorilla, each further divided into subspecies like the mountain gorilla and the Cross River gorilla. These magnificent animals primarily inhabit the tropical and subtropical forests of sub-Saharan Africa. Gorillas live in stable family groups, typically led by a dominant adult male known as a silverback, which maintains order and protects the group. These groups usually consist of several females and their offspring, with strong social bonds maintaining cohesion within the family unit.
How Gorillas Stand Apart from Other Apes
Gorillas distinguish themselves from other apes through several specific characteristics, particularly their considerable size and primary mode of locomotion. An adult male gorilla can weigh over 400 pounds and stand over six feet tall when upright, making them significantly larger and more robust than chimpanzees or bonobos, which typically weigh less than 150 pounds. While chimpanzees also knuckle-walk, their gait is more agile and less ponderous than the gorilla’s powerful, deliberate stride. Orangutans, by contrast, are primarily arboreal, moving slowly through trees using brachiation and climbing.
Dietary preferences also set gorillas apart; they are predominantly herbivorous, consuming large quantities of leaves, stems, and fruits. This contrasts with chimpanzees and bonobos, which have more varied omnivorous diets, including insects and small animals, or orangutans, whose diet is largely fruit-based. In terms of social organization, gorilla groups are stable, cohesive family units led by a single silverback, whereas chimpanzees live in larger, more fluid communities with multiple adult males. Gorillas also possess a range of distinct vocalizations, including chest-beating displays and specific calls that communicate alarm or contentment, contributing to their unique behavioral repertoire within the ape family.

Gorillas are the largest of all primates, known for their immense size and strength. They exhibit a distinct form of locomotion called knuckle-walking, where they support their upper body weight on the backs of their curled fingers as they move on all fours. Adult male gorillas, known as silverbacks, can also have a prominent sagittal crest, a bony ridge on top of their skull that anchors powerful jaw muscles, reflecting their strong chewing capabilities.
There are two main species of gorillas, the Eastern gorilla and the Western gorilla, each further divided into two subspecies. These include the Western lowland gorilla, Cross River gorilla, mountain gorilla, and Eastern lowland gorilla (also known as Grauer’s gorilla). These magnificent animals primarily inhabit the tropical and subtropical forests of sub-Saharan Africa. Gorillas live in stable family groups, typically led by a dominant adult male silverback, which makes decisions for the group and protects its members. These groups usually consist of several females and their offspring, with strong social bonds maintaining cohesion within the family unit.
How Gorillas Stand Apart from Other Apes
Gorillas distinguish themselves from other apes through several specific characteristics, particularly their considerable size and primary mode of locomotion. An adult male gorilla can weigh between 300 and 500 pounds (136 to 227 kg) and stand 4 to 6 feet tall when upright, making them much larger than chimpanzees or bonobos, which typically weigh between 70 to 130 pounds (32-60 kg) for males. While chimpanzees also knuckle-walk, their gait is generally more agile, whereas gorillas’ knuckle-walking is for weight-bearing and stability due to their robust build. Orangutans, by contrast, are primarily arboreal, moving through trees using brachiation.
Dietary preferences also set gorillas apart; they are predominantly herbivorous, consuming large quantities of leaves, stems, pith, shoots, and some fruits. This contrasts with chimpanzees and bonobos, which have more varied omnivorous diets that include insects and occasionally small mammals. In terms of social organization, gorilla groups are stable, cohesive family units led by a single silverback, in contrast to the larger, more fluid fission-fusion communities of chimpanzees where alliances can shift. Gorillas also possess a range of distinct vocalizations, including belches that signal contentment and roars or chest-beating displays that communicate aggression or warning.
