From a love of blubber to enormous paws, polar bears are remarkable animals,with many unusual adaptations that help them thrive in the Arctic.we wanted to share five of our favorite facts about what makes polar bears tick.

Number 1.

For a polar bear, home is on the sea ice.Polar bears rely on Arctic sea ice for their survival, a habitat that is literally melting away as the planet warms. They use the ice as a platform to hunt seals, to breed, to roam, and sometimes to den. Polar bears range across the circumpolar Arctic, in five “polar bear nations”: Canada, the U.S. (Alaska), Russia, Norway (Svalbard), and Denmark (Greenland). Canada is home to the most polar bears, approximately 2/3rds of the global number. (And, by the way, polar bears don’t live in Antarctica. Penguins do!)

Number 2.

Polar bears are BIG. In fact, they are the largest fourlegged predator. Adult males normally weight 350 to more than 600 kilograms (775 to more than 1,300 pounds). Adult females are smaller, normally weighing 150 to 290 kilograms (330 to 650 pounds). Scientists usually refer to how tall bears are by measuring them at the shoulder when on all fours. Those heights are typically 11.5 meters (3.35 feet) for adult polar bears. An adult male may reach over three meters (10 feet) when standing on its hind legs!

Number 3.

Polar bear cubs are born in dens hidden under the snow.After feeding throughout the winter and the spring sealpupping season, a pregnant female polar bear digs a den in the fall where she gives birth to her cubs and nurses them. After digging the den, she waits for snow to cover the entrance tunnel, blanketing it from view. The mother bear will emerge with her cubs in the spring and head to the sea ice to hunt seals—which means up to eight months with no meals for mom, an amazing feat.

Number 4.

Polar bears can eat over 100 pounds of blubber in one sitting!They are the most carnivorous of all bear species. Scientists sometimes call them lipovores because their main source of calories comes from marine fat, or blubber. Polar bears assimilate the majority of the fat they eat directly into their own body fat—and they don’t digest carbohydrates or proteins as well as brown bears do. Instead, they rely on seal prey reached via sea ice for the majority of their calories. The fat from seals keeps them going for much of the year and through times of extended fasting.

Number 5.

Polar bears are at the top of the Arctic food chain but rely on the entire food web to stay alive. Eightysix percent of the carbon that makes up the polar bear’s body is derived from the marine algae that grows within sea ice. Microorganisms like copepods eat the algae, fish eat the copepods, seals eat the fish, and polar bears eat the seals. Just as soil and plants form the base of a forest or meadow food chain, sea ice and algae form the base of the sea ice food chain, supporting polar bears at the top.

The situation is urgent, and we need to act soon—but it's important to remember that hope remains to save polar bears.We often hear overwhelming news about the Arctic and polar bears—but we know that if we take action now, we’ll see sea ice respond in time for the bears. And if societies do act to halt the rise in carbon emissions in time to save polar bears, it will benefit the rest of life on Earth, including humans.
