Gorilla (Gorilla)

A gorilla is the largest primate and another of the strongest animals in the world. Scientists recognize two species and four subspecies of gorillas; all species live in the tropical forests of equatorial Africa. Male gorillas can be 5.7 feet tall and weigh 606 pounds in captivity and 396 pounds in the wild.

Gorillas have imposing not only stocky bodies but also long, strong arms. Their arm span is longer than their standing height. Although gorillas are herbivores, their bite force of 1,300 psi can do serious damage in a fight with other animals.

There is currently no extensive research on how strong a gorilla is. But most authorities say an adult gorilla is about 4 to 9 times stronger than one human.
