The Eastern Lowland Gorilla, or Grauer's Gorilla, is the largest subspecies of gorilla, found in the dense forests of the eastern Democratic Republic of Congo. They have a stocky build, large hands, and a gentle demeanor. They live in social groups led by a dominant silverback, primarily feeding on fruit and vegetation.

Gorilla beringei graueri, commonly known as the Eastern lowland gorilla or Grauer's gorilla, is native to the eastern Democratic Republic of the Congo (DRC) in Central Africa. This species is primarily found in the lowland tropical rainforests of the region, with its range extending from east of the Lualaba River to the western edge of the Albertine Rift.

Grauer's gorillas inhabit dense, tropical lowland and montane forests. These forests are characterized by high humidity, substantial annual rainfall, and a stable warm climate. The altitudes at which they can be found range from 600 to 2,900 meters above sea level.

Grauer's gorillas are herbivorous and primarily feed on a variety of plant materials, including leaves, stems, and fruits. They play a crucial role in their ecosystem by aiding in seed dispersal and maintaining the health of the forest environment. Their social structure is typically composed of groups led by a dominant silverback male, with females, offspring, and sometimes other males.
