Both mountain and eastern lowland gorillas live in groups ranging in size from a handful of individuals to several dozen members. A dominant silverback—an adult male who shows his sexual maturity by the silver fur on his back—leads each group, which may include several subordinate silverbacks, blackbacks (adult males who have not yet reached sexual maturity), adult females, juveniles (ranging from age 4 to 8), and infants (age 3 or younger).
