Many animals once thought to hibernate, including bears, really only enter a lighter sleep-state called torpor. Like hibernation, torpor is a survival tactic used by animals to survive the winter months, and is triggered by colder temperatures and decreased food availability.
Why can a penguin not meet a polar bear?
Because they’re polar opposites! In Greek Arctic means bear while Antarctic means the opposite of Arctic (or opposite of bear). That’s why polar bears and penguins will never meet; they’re found in the north while penguins are found in the south. They are literally on opposite sides of the earth!
How can polar bears adapt to changing environments?
While polar bears have shown some ability to adapt to changes in their surroundings – for example, by foraging for food on land – scientists project polar bears will become more food-stressed as sea ice diminishes and populations will decline.
How far away can a polar bear smell an injured animal?

Do polar bears sleep in caves?

Can polar bears survive in warm climates?
Summary: Polar bears are not likely to survive in a warmer world, biologists report. As polar bears lose habitat due to global warming, these biologists say, they will be forced southward in search of alternative sources of food, where they will increasingly come into competition with grizzly bears.
Is polar bear hair white?
Polar bears have white fur so that they can camouflage into their environment. Their coat is so well camouflaged in Arctic environments that it can sometimes pass as a snow drift. Interestingly, the polar bear’s coat has no white pigment; in fact, a polar bear’s skin is black and its hairs are hollow.
Can polar bears smell humans 100 miles away?
Keen smelling is a polar bear talent Polar bears can smell seals and other animals up to 9 km (5.6 miles) away. They can even smell the breathing holes seals create in the ice from almost one km (.

Do polar bears stink?
Polar bears have smelly feet, scientists have discovered. Not just feet that are stinky because they are dirty, or unwashed. But feet that distribute scent, allowing the bears to leave chemical trails wherever they walk.
Do polar bears sleep in igloos?
Polar bears don’t den or hibernate as other bears do, but on particularly cold winters they will shelter beneath the snow in temporary dens, entering states of semi-hibernation called carnivore lethargy.
What animals can kill a polar bear?
Adult polar bears have no natural predators, though walruses and wolves can kill them.
What is the warmest temperature a polar bear can live in?
