On a recent visit to the world-famous San Diego Zoo, a family from central California witnessed something unsettling at the polar bear exhibit. A duck took a nose dive into the enclosure to enjoy the nice big pool of water, not realizing that the pool belonged to big white bears who don't mind a few feathers in their afternoon snacks. Upon seeing the unsuspecting duck, one of the bears lunged toward the bird and scooped it right up. It took a while it to decide the best way to eat the bird, but eventually the bear bit the duck's body and dove into the water, all while the family watched and filmed.
