Killer Whale? ...Try Savior Whale

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.

But when Yun, 26, tried to head to the surface she struggled to move her legs.

"I began to choke and sank even lower and I thought that was it for me - I was dead. Until I felt this incredible force under me driving me to the surface," Yun said.

Beluga whale Mila had spotted her difficulties and using her sensitive dolphin-like nose guided Yun safely to the surface.
