The life expectancy of wild gorillas is about 35 yrs, nevertheless captive gorillas have lived into their 40s.
Group succession, as witnessed in male mountain gorillas that stay of their natal groups, has not been observed in eastern lowland gorillas. If the silverback dies, the multi-woman group as well as their offspring may carry on to affiliate, rather than disperse, until finally a maturing silverback transfers in the team (Yamagiwa & Kahekwa 2001). a person achievable rationalization for this habits is protection from predators. as opposed to roaming with just their offspring, girls remain in teams of unrelated individuals to reduce prospect of getting attacked by leopards (Yamagiwa & Kahekwa 2001).
