Animals have a knack for saving other animals, but they've also been known to put themselves in the line of danger for humans -- and we're not just talking about pet dogs that protect their homes from burglars.

Whale Saves Diver
Athlete Yang Yun
was part of an underwater competition that required contestants to remain at to the bottom of a 20-foot arctic pool in China's Polar Land
when the freezing temperatures caused her legs to cramp, leaving her unable to return to the surface.
That's when one of the tank's residents, a beluga whale named Mila grabbed Yun's leg and guided her up toward the air.
