![]() ![]() Usually, only the dominant silverback has the right to reproduce, but there are exceptions. Silverback lives in polygyny and gathers a harem of as many females as possible. This rivalry means that adult male animals often live as loners for a long time before they fight to lead a group or after they have to surrender it. In the mountain gorillas of the Virunga volcanoes, a silverback leads his family for an average of 4.7 years before he dies or is disempowered by a rival. When the leader dies – be it due to illness, accident, or a fatal confrontation with poachers – his family usually disintegrates, she and looks for another dominant male who offers her the necessary protection. Male gorillas usually leave their family of origin at the age of eleven, but sometimes they remain in the group and take over their father’s family when he is forced to give up the tour due to his age. However, they will try to contest his leadership when they see the time. In addition to the leading silverback, there can also be other non-dominant silverbacks in a group. The physical proximity to him is an indication of the rank of the other members, especially that of the females. Therefore, they naturally have the full attention of the group, which is usually gathered around the silverback. They face both the challenge of another silverback gorillas that the group wants to take over and the threat from human poachers. They settle internal conflicts and make all the necessary decisions, such as regarding the time and direction of their group’s migration in search of the best feeding places. They are responsible for the cohesion, security, and well-being of their families.

The average height of a silverback is 1.7 meters, and it weighs up to 230 kilograms. ![]() Other unique features are the long canine teeth, an unusually large throat sac (to amplify the sound when breast drums), and a pronounced crest that the male gorilla develops over time. While the light coloration is limited to the back in the Eastern Gorillas, it can also extend to the hips and thighs in the Western Gorillas.
