Question

Did you know? Despite their white fur, polar bears have BLACK skin underneath. The black skin absorbs sunlight better in the polar summer; their white fur isn't actually white either — each hair is transparent and hollow, and appears white through light reflection.

Accepted Answer

Despite their white fur, polar bears have BLACK skin underneath. The black skin absorbs sunlight better in the polar summer; their white fur isn't actually white either — each hair is transparent and hollow, and appears white through light reflection.

Ondanks hun witte vacht hebben ijsberen ZWARTE huid eronder. De zwarte huid absorbeert beter zonlicht in de poolzomer; de witte vacht is bovendien ook geen wit — elke haar is doorzichtig en hol, en lijkt wit door licht-reflectie.
