Question

why are polar bears undetectable by infrared cameras

Answer 1

Answer:

Yes-

Explanation:

Polar bears are nearly undetectable by infrared cameras. Thermal cameras detect the heat lost by a subject as infrared, but polar bears are experts at conserving heat. The bears keep warm due to a thick layer of blubber under the skin. Add to this a dense fur coat and they can endure the chilliest Arctic day.

Answer 2

Answer:

Polar bear hair has a hollow core which effectively prevents the infrared emission, or heat signature, of the polar bear from escaping the fur. This helps the bear retain its heat and stay warm. ... When imaged with an infrared camera, only the exposed parts of the rabbit were detectable
