Just south of Banks Island in the Northwest Territories, 65-year-old Idaho hunter Jim Martell shot what he and his Inuit guides assumed was a polar bear. But a closer looked revealed the humped back and dished face of another bruin, creating a big stir among both hunters and biologists. "The probability of interbreeding of a polar and grizzly bear in the wild is pretty small, but it's not zero” Ian Stirling, Canada's leading polar bear expert, told the Calgary Herald. "So whatever this animal is, it's definitely very interesting." What’s also interesting is that Boone and Crockett may have a new record for a brand new category.
