Presentation

Western gorilla is the largest living primate, an impressive anthropoid ape characterized by its massive stature, exceptional strength, and remarkable intelligence. This herbivorous animal lives in structured social groups in the tropical forests of West and Central Africa.

The Western gorilla has a sturdy body covered in short, thick black hair, with very long, muscular arms. The adult male (silverback) is distinguished by a grayish tint on the back and hips. The face is bare, with small ears, expressive eyes and a broad nose with flattened nostrils.

CURRENT RANGE

Western gorilla is endemic to West and Central Africa. Its range extends over several countries including Equatorial Guinea, Gabon, Cameroon, the Republic of Congo and the Central African Republic. Residual populations are isolated and fragmented.

Behaviour

The Western gorilla lives in hierarchical family groups led by a dominant male (silverback) who protects and organizes the group. Individuals are generally calm and peaceful, spending most of their time feeding and resting. They communicate through vocalizations, gestures and facial expressions.

Reproduction

The female gorilla reaches sexual maturity around 8-9 years old and the male around 12-13 years old. Gestation lasts about 8.5 months, and the female usually gives birth to a single young. The young remain dependent on their mother for 3-4 years.

Peculiarities

Western gorilla possesses remarkable intelligence and learning ability, comparable to that of human children. Each individual has a distinct personality and can create and use tools. The very cohesive family structure and the strong emotional bonds between individuals constitute remarkable social particularities.

Threats and conservation

The Western gorilla faces serious and multiple threats: massive destruction of its forest habitat due to deforestation, poaching for bushmeat, illegal trade, and emerging diseases such as Ebola. Habitat fragmentation also limits the possibilities for reproduction and population expansion.

Numbers and trends vary across sources and regions. See the IUCN assessment for the latest reference data.
