This time of year, most #PolarBears are out on the sea ice, hunting seals, and getting ready to gorge during the seal pup season in the spring. Polar bears don't hibernate during the winter - they're actually really active!

Pregnant female #PolarBears will find a den & give birth to their cubs (usually in January/February) while in the den, & will not emerge until spring. This first year of life for cubs, especially time spent in the den, is critical for survival.

On average, only about half of #PolarBear cubs reach adulthood. In more vulnerable populations, those survival rates may be even lower.

Did you know? ⁉️❔

#PolarBears are #MarineMammals. Because they spend so much time on the sea ice (at least half of their lives), and because they depend on the marine ecosystem and sea ice for survival, they are marine mammals.

In fact, #PolarBears are great swimmers! They use their front paws to propel themselves through the water, & their back paws to steer, just like rudders. The longest recorded swim was over 9 days, & the bear covered 426 miles/687 kilometers.

#PolarBears are actually highly adapted to exist & thrive in an Arctic environment. Small round ears & a small tail help prevent heat loss. Translucent, hollow fur over black skin reflects heat back to the body. But they can overheat!
