Silverback gorilla strength is one of the most talked-about traits of the world’s largest living primate. Gorillas share up to 98% of their DNA with humans and are split into four species: mountain gorillas, eastern lowland gorillas, western lowland gorillas, and river gorillas. Of these, mountain gorillas are the strongest and the most sought after on gorilla trekking tours, found only in the Virunga Conservation Area of East and Central Africa.
What Makes a Gorilla a Silverback
A silverback is the dominant adult male in a gorilla family, named for the patch of silver hair that develops across his back and flanks once fully grown, usually around age 13. At this point, most males leave their birth family to join or challenge another group for dominance. Silverbacks average 400 pounds and stand up to 6 feet tall on two legs, noticeably larger than adult females, who average 200 pounds and stand around 4 feet tall. Their skulls also carry a bony ridge that anchors their powerful jaw muscles, giving them a more pronounced head shape than females. A silverback’s arms stretch 2.3 to 2.6 meters, longer in proportion than a female’s.
As the family’s leader, a silverback decides when and where the group feeds, rests, and moves, and takes on breeding rights with the group’s females. Gorilla families typically range from 2 to 40 members, though most families sit somewhere in the middle of that range.
Why Silverbacks Are So Strong
A silverback’s strength comes from a combination of a plant-based diet, large muscle mass, and dense, reinforced bone structure built to handle heavy physical stress. Their arm muscles are considerably larger than their leg muscles, since gorillas rely heavily on their arms for movement and climbing.
Silverback Strength Facts
A silverback’s grip is strong enough to crush a mature crocodile, and despite their size, they can still climb trees and move between branches with ease. Their bite carries around 1,300 PSI of force, and a silverback can carry more than 815kg (1,800 lbs) of dead weight. By most estimates, an adult silverback is 4 to 9 times stronger than an average human, putting them among the 10 strongest animals in the world pound for pound.
Are Silverbacks Dangerous?
Despite this strength, silverbacks rarely use it against other animals or people. They’re generally calm and reserved, saving their power for defending the family from a genuine threat, whether that’s another silverback challenging for dominance or a perceived danger to the group. Since gorillas are vegetarian, that strength isn’t used for hunting either.
Seeing a silverback up close, especially if he beats his chest to display his strength, is one of the most memorable moments of any gorilla trek. Book your gorilla trekking safari with our team today, and get the chance to witness this strength firsthand in the wild.
