A beluga whale saved a drowning diver by hoisting her to the surface, carrying her leg in its mouth. Terrified Yang Yun thought she was going to die when her legs were paralyzed by crippling cramps in arctic temperatures. Competitors had to sink to the bottom of an aquarium's 20-foot arctic pool and stay there for as long as possible with the beluga whales at Polar Land in Harbin, north east China. Beluga whale Mila had spotted her difficulties and using her sensitive dolphin-like nose guided Yun safely to the surface.
