A remarkable new story is unfolding in the Arctic, one that has never been told before. As the ice shrinks, the polar bear is struggling to survive in a fast melting world. Polar bears are great hunters on ice but recently their home ground is vanishing from under their feet. Although classified as a marine mammal, the polar bear is not adapted to hunting in the water despite being able to swim huge distances. And they are certainly no match for the world's greatest aquatic hunter -- the killer whale. In the last few years, scientists have started noting an ever-growing number of killer whales in Arctic waters in the summer months. More and more have been attracted to these huge hunting grounds by the growing expanses of open water. And they are attacking exactly the same prey animals as the polar bears: seals, narwhal, belugas and bowhead whales.
