LIFE SPAN: Gorillas normally live 35-40 years in the wild and up to 50 years in captivity.

HABITAT: Western Gorillas live in West Central Africa, and Eastern Gorillas inhabit East Central Africa. Gorillas typically live in forests, swamps, and marshes.

DIET:  Gorillas are herbivores (vegetation eaters) who eat fruits, leaves, bark, buds, and stems. They also occasionally eat small invertebrates such as ants, termites, and worms.

A male Gorilla is called a silverback (older male) and a black back (younger male)

A female Gorilla is called a gorilla (there is no word that distinguishes a female gorilla by her gender)

A young Gorilla is called an infant

A group of Gorillas is called a band or a troop

Gorillas, the largest of the primates, are closely related to humans. Ninety-eight percent of their DNA is identical to that of humans!

Gorillas have fingerprints like humans do

Gorillas spend their daily lives engaged in three basic activities- eating, traveling, and resting

Gorillas are quadrupedal, which means that they move around by walking on their knuckles.

Gorillas play a vital role in seed dispersal. Many large fruit trees depend upon these roaming herbivores to survive as gorillas scatter their seeds as they travel from place to place.

Eastern Gorillas are considered Endangered and Western Gorillas are considered Critically Endangered according to the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. This means that Eastern and Western Gorillas are facing a high risk and an extremely high risk respectively of becoming extinct in the wild.  

It is likely that fewer than 5,000 Eastern Gorillas remain in the wild today. This is down from in 1995 when 16,900 were estimated to be existing in the wild.   Widespread habitat insecurity and poaching for bushmeat (especially around mining camps) have led to the Eastern Gorilla population to become increasingly fragmented and their numbers to be greatly reduced.

Western Gorillas are facing an 80% population decline over three generations (one generation equals 22 years according to the IUCN). This massive population decline is being caused by illegal hunting, disease and habitat loss.

Educate yourself about Gorillas and their circumstances by reviewing the materials presented below in the Resources section and other materials you may be able to find on your own.

Post messages on social media platforms such as Facebook, Twitter, and Instagram and send emails to your family and friends expressing your concern for the plight of the Gorillas and encouraging them to become involved as well.

Write letters to your elected officials in Washington DC and to leaders in nations where Gorillas live explaining why the conservation of Gorillas is important to you and encouraging these officials to work to help keep Gorillas from ever becoming extinct in the wild.

Help to improve the environment around you and around the world by working to reduce, recycle, and reuse. This will help eliminate waste and will greatly improve the world in which we all live.
