Polar bears are only found in the frozen wilderness of the Arctic, which includes Canada, Alaska, the United States of America, Greenland, Russia, and Norway.
Guys, these are some really big bears. Polar bears can grow to be more than 2.5m long and weigh about 680kg as adults. They are the biggest meat-eaters on Earth because they are so big and heavy.
Polar bears can thrive in one of Earth's toughest environments. In addition to their thick fur, they contain blubber, which insulates them from cold air and water. Polar bears' black skin helps them absorb the Sun's rays and stay warm.
These amazing beasts utilise their acute sense of smell to locate their preferred prey, the seals*. Their sense of smell is so acute that they may locate prey up to 16 kilometres distant.
Despite their bulk, polar bears can swim up to 100 kilometres away from land. When utilising their webbed, 30cm paws as paddles, they can swim at a speed of 10km/h.
Polar bears can swim well, however they can't capture seals while swimming. They hunt on ice. They wait near seal breathing holes or on the ice's edge for one to surface. Then they pull it out and gulp.
Did you know polar bears actually have brown fur? It has a hollow centre that reflects light, making it appear translucent. Because of this, the bears are better able to blend in with their environment, which is especially helpful while hunting cautious seals.
In November or December, polar bear mothers give birth to their cubs in snow dens, shielding them from the elements. The newborn cubs are about the size of a guinea pig, measuring 30 centimetres in length and weighing about 500 grammes.
After around four or five months, the polar family emerges from the den. It takes around two years for a mother and her cubs to learn everything they need to know to survive in the Arctic.
These magnificent animals are unfortunately considered "vulnerable." Climate change is the greatest threat to polar bears. Polar bears have less time to hunt for food as global warming causes sea ice to melt and form later each year. Here's the good news: you can aid these amazing creatures.
