True animal rescuers stop at nothing to help those in desperate need, sometimes even risking their own lives. Bluewater Explore and Whale Swim & Dive Tours on the island of Tonga were diving in the waters at the most opportune time. A large humpback mother whale and her calf were seen swimming together but there's just one problem... Momma is wrapped in a buoy. Her deep cries for help were only reassurance for diver Cole Harrison and the others to come to her aid. br br If they hadn't of freed her, there is a good chance her calf would have suffered from starvation. It's people like this that make our world a much better place.
