Gorillas, like humans use a series of facial expressions and body movements to convey messages and emotions.Ĭhest beating, staring with pursed lips and a tensed mouth with teeth bared. Unlike humans they have large Laryngeal sacs within their vocal chamber which can be filled with up to seven litres of air, and used to increase the volume of their calls. Gorillas produce over 20 recognized sounds, each with unique meaning. They usually travel alone or with a group of other males until they can attract a mate. When they reach sexual maturity at the age of ten they leave their family groups to join another or form their own and find a mate. They support the leader and help them forage. Younger male gorillas are called blackbacks because they have not yet developed silver hair on their back like mature males, though all males will not necessarily develop a silver back. As part of a gorilla language project, Koko a western lowland gorilla has been taught American Sign Language and has mastered 1,000 words. Some gorillas in captivity have been taught to communicate with humans.
