Gorilla arms are longer than their legs.
Measured from fingertip to fingertip on outstretched arms, the longest span measured was nine feet, two inches.
However, a more typical adult male arm span is about eight feet.
Because of their long arms, Gorillas can move around by knuckle-walking. They also live on the ground instead of in the trees like most monkeys.
Gorillas also share the same blood type within the species, and even have different fingerprints like humans.
