The mountain gorilla is a subspecies of the eastern gorilla, primarily found in the mountainous regions of Virunga National Park in Rwanda, Uganda, and the Democratic Republic of the Congo. They are known for their thick fur, which helps them survive in cooler climates, and can weigh between 300 to 485 pounds. Mountain gorillas live in groups called troops, led by a dominant male known as a silverback. These gorillas are herbivorous, primarily feeding on leaves, stems, and fruits. They play a crucial role in their ecosystem by helping to disperse seeds and maintain forest health. Unfortunately, mountain gorillas are critically endangered due to habitat loss, poaching, and disease, making conservation efforts essential for their survival.
