The mountain gorilla (Gorilla beringei beringei) is a critically endangered subspecies of eastern gorilla, uniquely adapted to high-altitude montane forests in central Africa and renowned for its robust build and complex social behaviors.
First described by Paul Matschie in 1903, the mountain gorilla inhabits isolated populations in the Virunga Volcanoes spanning Rwanda, Uganda, and the Democratic Republic of the Congo, as well as Uganda's Bwindi Impenetrable National Park. This subspecies evolved to thrive in cold, wet montane environments without any known artificial breeding or hybridization.
The mountain gorilla is one of two subspecies of Gorilla beringei, within the tribe Gorillini of the subfamily Homininae, family Hominidae, and superfamily Hominoidea. It shares its lineage with the eastern lowland gorilla (Gorilla beringei graueri), distinguishing itself by habitat and morphological traits.
Mountain gorillas are the largest living primates, with adult males reaching up to 170 cm in height and weighing between 140 and 205 kg, while females are smaller, averaging 70 to 115 kg. They possess dense, long fur that insulates them against cold montane climates. Distinctive features include pronounced brow ridges, broad chests, muscular limbs, and thick fur that sets them apart from other gorilla subspecies.
These gorillas are diurnal and terrestrial, building nests daily for rest. They live in cohesive troops led by a dominant silverback male, exhibiting complex social interactions. Their slow reproductive rate involves females giving birth every 4 to 6 years, with extended parental care. Mountain gorillas play a vital role in their ecosystem and are a focus of ecotourism, which supports conservation efforts while minimizing disturbance.

Known locally as "Ingagi" in Kinyarwanda and "Mbega" in Swahili, they inspire ecotourism that benefits local communities. Their image symbolizes wildlife preservation and has influenced art, documentaries, and international conservation campaigns, emphasizing the importance of protecting endangered species.
Mountain gorillas are restricted to high-altitude montane forests ranging from 1,500 to 4,000 meters in central Africa. Their populations are confined to the Virunga Volcanoes region, which spans Rwanda, Uganda, and the Democratic Republic of the Congo, and the Bwindi Impenetrable National Park in Uganda. These dense, moist forests provide the cool climate and vegetation essential for their survival.
Mountain gorillas live in cohesive troops typically led by a dominant silverback male. These groups include multiple adult females, their offspring, and subordinate males. Social bonds are strong, with the silverback providing protection and leadership. Group sizes vary but generally maintain stable hierarchies and cooperative care of young, reflecting complex social dynamics.
The mountain gorilla's diet is primarily folivorous, consisting of leaves, shoots, stems, and bark, supplemented occasionally by fruit. Invertebrate consumption is rare. Their feeding habits reflect adaptation to the montane forest environment, where fibrous plant material forms the bulk of their nutrition.
Classified as Critically Endangered, mountain gorillas face major threats from habitat destruction, poaching, and vulnerability to human respiratory diseases. Conservation efforts focus on habitat protection, anti-poaching patrols, and regulated ecotourism to minimize disease transmission. They are strictly protected under national laws and listed on CITES Appendix I, prohibiting hunting and trade.
Mountain gorillas belong to the subspecies Gorilla beringei beringei, genetically distinct yet closely related to the eastern lowland gorilla. Genetic studies reveal differentiation between Virunga and Bwindi populations, although not formally recognized taxonomically. No artificial hybridization has been recorded, and they share the evolutionary lineage characteristic of great apes within the Hominidae family.
