The Western gorilla is one of two species of gorillas, primarily found in the forests of Central Africa. They are known for their large size, with adult males weighing up to 440 pounds. Their fur is typically dark brown or black, and they have a distinctive broad chest and strong arms. These gorillas are social animals, living in groups called troops, which are led by a dominant male known as a silverback. They primarily eat leaves, fruits, and stems, playing a crucial role in their ecosystem by helping to disperse seeds.
