A beluga whale came to the rescue of a woman who got into trouble during a free-diving contest at a Chinese aquarium, the Telegraph reports. The woman, who wasn't wearing breathing equipment, suffered cramps near the bottom of the aquarium's Arctic pool and found herself unable to rise. The whale, sensing she was in trouble, took her leg and guided her to the surface.
"I began to choke and sank even lower and I thought that was it for me—I was dead," the diver says. "Until I felt this incredible force under me driving me to the surface." (More marine mammals stories.)
