Beautiful and rare, the gorilla is a creature known for its strength and intelligence. Observing a gorilla will surely remind you of being a human, especially since gorillas have been studied for their human behaviors. But how long do gorillas live, and what is their life like?

In this article, we will discuss how long gorillas live, what their average life cycle is like, and we will even mention some of the oldest living gorillas on record. Some of these gorillas have lived long and impressive lives, both in captivity and in the wild. Let’s learn more!

How Long Do Gorillas Live?

Gorillas live for 20 to 40 years in the wild.

Gorillas live an average of 20 to 40 years in the wild. Captive gorillas live longer lives, though a wild gorilla does not face many natural predators. Given their size, strength, and intelligence, the main predator of gorillas is mankind.

Gorillas and humankind are closely linked genetically, and many studies have shown that gorillas are similar to us in many ways. For example, one study shows that gorillas eat food with joy and vocal exclamations, similar to how we feel when we enjoy a good meal. 

Gorillas are also naturally strong and powerful. They have been known to bend cage bars when kept in captivity, and they can easily uproot trees in the wild. This makes gorillas sound disruptive to a natural environment, but the opposite is actually true.

Given that gorillas are primarily herbivores, they often consume plant matter and seeds. They defecate in areas that are well-lit and moist, and are always on the move. This means that they leave these areas of the forest undisturbed, allowing the seeds in their waste to grow and reproduce plants. 

Gorillas are also similar to us in that we call their babies infants. This is the scientific term for a baby gorilla, and it only makes sense, given our close genetic link and the similarities to how we treat our young. But let’s dive into what life is like for an infant gorilla now. 

The Average Gorilla Life Cycle

Gorillas are fully grown when they reach 7 to 12 years of age.

From newborn gorilla to grown silverback male, here is what the average gorilla life cycle is like! 

Newborn, or Infant 

It is important to note that the average female gorilla can only produce offspring every two to six years, depending on her health. The gestation period for an infant gorilla is similar to that of humans, lasting roughly eight to nine months. A mother gorilla only gives birth to one baby at a time, and her breeding season is often short. This is part of the reason why gorillas are an endangered or threatened species.

An infant gorilla lives its life similarly to a human baby. It is incapable of walking for the first three to five months of its life, and only learn how to sit up after at least six to ten weeks as well. It takes at least six months for an infant gorilla to walk on its own. Even after the initial six months have passed, an infant gorilla still clings to its mother’s back until its third or fourth year of life. 

Young Gorillas

Even after the initial six months have passed, an infant gorilla still clings to its mother’s back until its third or fourth year of life.

Young gorillas begin to gain more independence once they have reached just under five years of age. They still remain with their mother for quite some time, but they are capable of walking around on their own and fending for themselves.

Young gorillas grow rapidly during this time, and male and female gorillas grow at the same rate. They are curious, playful, and learning many different socialization customs that gorillas have. This can include up to 30 different vocalizations and sounds that gorillas use to communicate. 

Adult Gorillas

Most gorillas are considered adults when they reach the age of sexual maturity. Female gorillas mature more quickly than males, and this occurs between 7 to 9 years of age, while male gorillas need an average of 10 to 12 years. 

However, there is still a great deal of time before males start to turn gray. Silverback gorillas are not a particular species of gorilla, as the phrase merely refers to a more mature adult male gorilla. Female gorillas do not have this coloring and are usually smaller than male gorillas.

Male gorillas can reach nearly six feet tall when standing, and can weigh almost 500 pounds. Female gorillas can weigh similarly, especially when they are pregnant. A group of gorillas is called a troop and is formed with a single silverback male, many females, and their babies. 

Some of the Oldest Gorillas Ever!

One of the oldest known gorillas was 63 years old.

While gorillas can live a long and healthy life in the wild, they can live even longer when kept in captivity. Curious to know how old some of the oldest gorillas ever recorded are? Here is a list of some famous old gorillas! 

  • Trudy lived to the ripe old age of 63 at the Little Rock Zoo. She was born in the wild and was one of the last gorillas to be caught and brought into captivity.
  • Ozzie lived at Zoo Atlanta and passed away in January 2022, having celebrated his 60th birthday in June 2021.
  • Another gorilla at Zoo Atlanta, Choomba, passed away at the age of 59.
  • Fatou, a gorilla still alive and well at the Berlin Zoo, currently holds the title for the oldest gorilla in captivity. She turned 68 years old in April 2025!

Also, while Koko only lived to the age of 46, she was a wonderful gorilla for many reasons. Born on the Fourth of July at the San Francisco Zoo, Koko learned over 2000 words in sign language and could readily communicate with humans.
