Polar Bears Are Nearly Invisible On Infrared Cameras
If you’re out to beat a polar bear’s stealth, don’t attempt to do it with infrared vision. While special infrared cameras work by picking up on the heat emitted by a subject, polar bears are experts at conserving their own body warmth. Given that they live in some of the coldest climates on earth, they have a dense fur coat and a super think layer of blubber under their skin. These act like a sort of super coat that helps conserve their body heat.
