Watch This Polar Bear Eat A Very Unlucky Duck At A Zoo

This is one of those things that happens in nature, and also at the zoo in San Diego. You would think that a duck would notice a polar bear swimming underneath them, but not in this case. That polar bear is SNEAKY! Then again when you're a duck in San Diego I'm pretty sure that the last thing that you need to be worried about is getting swallowed by a polar bear. It isn't even on your radar. But in this case we are just lucky that a tourist was shooting video and we are able to watch it all happen!
