Because of the dedication of an American biologist, Dr. Herbert Lang, these animals were given government protection and their homeland was made into a national park. Today, more than 3,500 southern white rhinos survive in well-protected parks and reserves. All of these animals are descendants of that one small herd. A native of central Africa, this is one of three sub-species of gorillas. The males can weigh 450 pounds or more.
Gorillas are very gentle creatures.
They live under cover of the jungle in small bands of 10 to 20 members, eating mainly leaves and stems. Each band is led by a silverback, a male whose back is frosted gray, indicating maturity. He guides the others in search of food and resting places. Although the dominant silverback will fight to defend his family, it is seldom necessary. The gorilla replaces force with intimidation, preferring a lively chest-beating display.
