They were originally bred to resemble pigs represented in ancient European prehistoric artwork of the Iron Age. Their feet are partly covered in fur, intermediate between the bare paws of grizzlies and the fuzzy feet of polar bears.

Back in 2010, reports of a possible hybrid between Burmese pythons and African rock pythons which have been known to attack humans stoked fears that it could give rise to an unusually aggressive super-predator.

With climate change warming the planet, the arctic ice is melting at an alarmingly rapid rate. However, in the 1980s, their progress came to a halt due to economic difficulties and fear that ubros would breed with native wisents, causing genetic pollution. Tiger trout are good examples of this. A single hybrid population now prevails. The Pizzly Bear, which was first documented in 2006, doesn't have as much blubber as the polar bear.

Unless it's mating season, which for both species falls in the spring. Rather than grolar bears taking over the Arctic, the real risk is that what we know as polar bears will simply be absorbed into a tide of grizzly DNA through successive crossbreeding events.
