Question

Did you know? Polar bears have black skin beneath their white-translucent fur — the black skin absorbs UV radiation and converts it to heat. Their hairs are also hollow, acting like an insulating thermos.

Accepted Answer

Polar bears have black skin beneath their white-translucent fur — the black skin absorbs UV radiation and converts it to heat. Their hairs are also hollow, acting like an insulating thermos.

IJsberen hebben zwarte huid onder hun wit-doorzichtige vacht — de zwarte huid absorbeert UV-straling en zet het om in warmte. Hun haren zijn bovendien hol, waardoor ze als isolerende thermos werken.
