The western lowland gorilla is a subspecies of the western gorilla, primarily found in the rainforests of central Africa. They are known for their distinctive physical features, including a broad chest, large hands, and a stocky build. Adult males can weigh up to 400 pounds, while females are smaller, averaging around 200 pounds. Their fur is typically dark brown or black, with a lighter patch on the chest. These gorillas are primarily herbivorous, feeding on leaves, fruits, and stems. They live in social groups called troops, led by a dominant male known as a silverback. Western lowland gorillas are critically endangered due to habitat loss, poaching, and disease, making conservation efforts essential for their survival.
