Most mountain and lowland gorillas stand between 4 and 6 feet tall and weigh between 150 and 500 pounds. Gorillas are known to be among some of the strongest and most intelligent animals. However, because gorillas have a vegetarian diet, they do not hunt other animals. Gorillas in the wild live about 35 years on average.
Mountain gorillas are mostly found in the mountains and forests of central Africa. This is an area that has seen more than its share of violence among humans in recent years. This violence has also affected the number of surviving mountain gorillas, thus making mountain gorillas endangered.
Thanks to conservation and rescue efforts, the number of gorillas seems to be increasing, albeit slowly. Even though gorillas are able to climb trees, they are found on the ground much more often than other kinds of primates.
Mountain gorillas live in groups of about 30 or fewer members. Lowland gorillas live in families of between four and eight members. The groups are led by a dominant male but also include younger males, several females and the offspring of the females. Although dominant male gorillas can be intimidating when challenged, they typically prefer to avoid confrontation and live in peace. The younger individuals in a group are similar to human children, as they spend the first few years of life chasing one another, climbing trees and swinging from branch to branch.
