Grauer's gorilla, also known as the eastern lowland gorilla, is a subspecies of the western gorilla. It is primarily found in the dense forests of the Democratic Republic of the Congo. This gorilla is the largest of all gorilla subspecies and is known for its robust build and long arms. These gorillas are herbivorous, feeding mainly on leaves, fruits, and stems. They live in groups called troops, which are led by a dominant male known as a silverback. Unfortunately, Grauer's gorilla is classified as critically endangered due to habitat loss and poaching, making conservation efforts essential for its survival.
