Some Inuit have said that polar bears can smell your fear. Like, when you encounter one and you didn't bring your gun, they'll know, cause you'll be shiznitting yourself instead of shouldering your weapon.
A tracked polar bear swam a distance of 400kms over two weeks without getting out of the water.
A polar bear's fur, the guard hairs are hollow, serving to trap air, maintain heat and help with bouyancy in the water. And the hair isn't white, it's clear, while the skin is all black.
Northern Russians used to trade polar bear canines as talismans to southerners. To carry the tooth would help ward off grizzlies, the polar bear being the superior beast.
World largest polar bear on record is 2209 pounds, the grizzly (grown large in captivity) 2130 pounds. Polar bears are the strongest bear by bite force and endurance, their average range is far superior, they don't hibernate, they're more apt to not take risk. Grizzlies are more aggressive, meaner, larger claws and likely to fight.
In Nunavut the most expensive hunts are through Resolute and Grise Fiord. The largest bears are the furthest north. Hunter's pay $60,000-$70,000 on average per hunt. The Wildlife Office issues only so many tags per year. The community keeps the bear meat and pelt as these are not exportable to the U.S. and some other countries. On a recent trip home from Grise Fiord I met two hunters so filthy rich they wipe they're arzes with Benjamin Franklins. One got his bear in Grise, the other did not get his in Resolute. They've killed everything from giraffes, elephants, rhinos, lions and one fella all but 1 of the 28 big game animals of North America. I don't see the sense in it but, if they're not pulling the trigger and paying big bucks to Arctic communities, then the Inuit are pulling the trigger and asking big bucks for pelts.
