Thanks to special adaptations, such as a thick layer of blubber, two layers of fur, compact ears, and a small tail, polar bears can withstand temperatures as low as -50° Fahrenheit.
Can polar bears freeze to death?
That does not mean, however, that they cannot freeze to death, only that they have the means to tolerate colder climes than most animals can abide. Of course it can. Polar bears may be well adapted to Arctic temperatures (-30 F) but not to Antarctic temperatures (which can go down to -130 F).
What temperature does a polar bear need to survive?
Inhabiting the ice and sea of the Arctic, polar bears are well-equipped for survival in a harsh environment. Two coats of fur and a thick layer of blubber help insulate the polar bear’s body from the cold, keeping its temperature at an even 37° C (98.6° F).
How does a polar bear tolerate extreme cold?
Blubber is a thick, insulating layer of fat beneath the skin that helps to keep body warmth in and the cold of the air or water out. Polar bears have an extra thick layer of fat (or blubber) up to 10cm thick which helps to keep them warm in very cold regions.
Do polar bears eat fish?
Food Preferences & Resources
When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.
Do polar bears eat penguins?
Polar bears do not eat penguins, since penguins live in the southern hemisphere and polar bears live in the northern hemisphere.
What is the average lifespan of a polar bear?
LIFE CYCLE: Polar bears can live up to 25 or 30 years in the wild.
Do polar bears get cold?
You would think that in their icy, arctic environment, polar bears spend most of their time shivering with cold! … A polar bear’s body temperature runs around 98.6º Fahrenheit, typical for most mammals, but their adaptation to cold weather means they have an unfortunate propensity to overheat.
What animal can withstand the coldest temperatures?
But many mysteries remain. The arctic ground squirrel, the only mammal to survive subzero body temperatures for extended periods of time, could offer our best chance of safely entering the world of subzero tissue preservation. It’s just about possible that, one day, a squirrel could save your life.
