Kuptana, had been hunting for polar bears, and killed the animal believing it to be a normal polar bear. Officials took interest in the creature after noticing that while it had thick, creamy white fur typical of polar bears, it also had long claws, a humped back, a shallow face, and brown patches around its eyes, nose, back, and foot, which are all traits of grizzly bears. If the bear had been adjudicated to be a grizzly, the hunter would have faced a possible CAN$1,000 fine and up to a year in jail. A DNA test conducted by Wildlife Genetics International in British Columbia confirmed it was a hybrid, with a polar bear mother and a grizzly bear father. It is the first documented case in the wild, though it was known that this hybrid was biologically possible and other ursid hybrids have been bred in zoos in the past. On May 8, 2006, the discovery of the grizzly-polar bear hybrid received increased attention when, soon after the story was announced, the comedy television show The Colbert Report light-heartedly named the new species as the number one threat to American Security. Amidst much controversy, the bear has since been returned to Martell. Subsequent discoveries On April 8, 2010, David Kuptana, an Inuvialuit hunter from the community of Ulukhaktok on Victoria Island shot what he thought was a polar bear. After inspecting the bear and having its DNA tested, it was discovered that the bear's mother was a grizzly-polar hybrid and the father was a grizzly bear. The bear possesses physical characteristics intermediate between grizzlies and polar bears, such as brown fur on its paws, long claws, and a grizzly-like head. Between 2012 and 2014 another six hybrid bears were either killed by hunters or live-captured by biologists. Samples were collected from all six, and genetic analysis confirmed both their hybrid status and their family relationships. The eight hybrids identified to date include four first-generation (F1, 50:50) and four grizzly bear backcross individuals (75:25 grizzly:polar bear). A single F1 female was the mother of all four backcross individuals, and a single female polar bear was the mother of all four F1s, and thus the grandmother of all four backcross bears. Two male grizzlies mated with the female polar bear to give rise to the four F1s, with one grizzly bear apparently mating with the polar bear in two different years (two
