Male gorillas often beat their fists on their chests. They do so to show who is the strongest in the group. However, it can also be a kind of greeting. Gorillas don’t just walk on the palms of their hands, but also on their knuckles. For this reason, they’re also known as knuckle-walkers.
Male gorillas can weigh up to 200 kg.
