The group of gorillas is led by the male with the greatest strength and experience. This male is called a silverback and is usually the father of most of the young in the troop. Silverbacks are very important members of the gorilla troop and are responsible for protecting the family from predators and other threats. They are also responsible for resolving conflicts within the troop. Its name comes from the silvery hair on its back, which begins to appear at the age of twelve and is a feature of adult males only.
