Additional Details ------------------------------ Product description: Romain Baertsoen filmed the amazing gorillas of the Viruga Mountains, where we witness young gorillas playing, resting, and feeding or aggressive 400-pound adult Silverbacks. In one extraordinary incident, we actually see gorillas trying to help a dog that is caught in a trap by using sign language. Baertsoen also filmed spectacular footage of one of the Congo's erupting volcanoes and we see how the cooled lava provides a fertile land for flora and fauna.
