EXCLUSIVE: Male Polar Bear Chases and Eats Cub

Warning: Graphic Images

Polar bear cannibalism likely isn't a rare event, but it's rarely witnessed by people. This may be the first time it's been captured so well on video. During a Lindblad Expeditions trip on the National Geographic Explorer in the Arctic, crew and passengers spotted a male polar bear hunting and then eating a polar bear cub, despite the efforts of the cub's mother to protect it. Experts say this cannibalistic behavior could be occurring more regularly, because the loss of ice due to climate change makes it harder for the bears to get to their typical food sources.
