Gorillas are strong

The largest primate, which includes humans, is the gorilla. They typically average up to 440 pounds, although records show that they can weigh up to 485 pounds. When they are standing upright, they are 4-6 feet tall, but because of their broad shoulders, they are also very wide. The eastern lowland gorilla is larger than the western lowland gorilla, which tends to be smaller. The largest gorilla ever recorded as of 2014 was Phil, a gorilla at the St. Louis Zoo who weighed 860 pounds and stood just under six feet tall, according to Fox News.

Gorillas have vast, complicated digestive systems that enable them to ingest mostly vegetation, including some forms of wood, explaining their massive, spherical bellies. Their strong arms and backs allow them to lift, push, and strike much more forcefully than a person of the same size. This is made possible by their muscular, broad chests and extended arm width, which can be up to a foot larger than that of humans. Undoubtedly extremely powerful, a mature gorilla may be up to ten times more powerful than an adult male. Banana trees may easily be torn down by gorillas, and their bite is nearly twice as powerful as a lion's. They have also been known to bend metal bars to escape from cages.
