More Information

Western lowland gorillas, one of the largest living primates, can grow up to six feet tall and over 400 pounds. All gorillas have a black coat, but adult males also have a silvery-white “saddle” on their back. Gorillas are herbivorous, primarily feeding on leaves, stems, and fruit. Troops are made up of a dominant silverback, multiple females, and their young. Mating is non-seasonal and offspring are born after nine months. After maturing, males leave to form their own troop or join a bachelor group while females leave to join another established group.

Did You Know?

Gorillas form a tight-knit family group protected by a silverback. They are very gentle, sensitive, and intelligent.

While displaying their most famous gesture, gorillas stand on their back two legs and beat their chest with open hands—not clenched fists as often shown on television.

Lincoln Park Zoo scientists study gorillas through behavior and health monitoring, voluntary tool-use studies, and computer touchscreen sessions.
