What colour do you think Polar bear fur is? That might seem like a silly question but the answer might surprise you. HINT: it’s not white! Polar bear fur is actually clear! That’s right! CLEAR!
But if the Polar bear’s skin is black, how come they don’t look black in colour? Well, each of the longer guard hairs on the Polar bear’s body is hollow and reflects visible light, much like snow. So when the sun is shining brightly, Polar bears appear bright white.
Since these hairs are hollow, the Polar bears’ diet and environment can affect their colour. Polar bears whose diet has a lot of seals in it can look light yellow because of the seal oils. Polar bears that live in warmer climates (like in zoos) can have algae growing in their hair, which can make them look green! Don’t worry, being green doesn’t cause the Polar bear any harm and a bath with special salt solution turns them white again.

Dear Ranger56120723,
Actually, it’s spelled ‘extinct’ but you’re helping by drinking bottled water. If you boil water from the tap and freeze it it’s the kind of water you should drink to help save Polar Bears.
Your Fellow Earth-Ranger,
Alishia
clear because the fur reflects off the snow.

WOW!
