Interesting Facts About Polar Bears: Largest Species Of Bears

Polar bears are one of the most iconic and well-loved species in the world. Despite this, these majestic and awe-inspiring bears are under serious threat from climate change, which has left their sea ice habitat dwindling. Since 1972 WWF has worked hard to fight the challenges that polar bears are facing and secure them a safer future.
Polar bears are largest species of bears and largest land predators. They live in Arctic region of Russia, Alaska, Canada, Greenland, and Norway. Polar bears are well adapted to survive in one of the harshest environments on our planet.
As well as their thick fur, they have a layer of fat, called blubber, that insulates (protects) their bodies from the frosty air and near-freezing water. Polar bears also have black skin under their glistening coat, which helps them soak up the Sun’s rays and keep warm.
Due to their large size, they have no natural enemies, except humans. Main factors that negatively affect their survival are global warming and melting of the polar ice caps, pollution of the sea and oil spills. They are on the list of threatened species with only 20 000 animals left in the wild.
Here are some interesting facts about polar bears:
1. Although they look white, their fur is transparent. When light bounces back from the fur, result is a white color, combination of all colors. Thanks to the white color, they blend with their environment easily.
2. Male polar bear can reach 10 feet in length and weigh up to 1500 pounds. Females are two times smaller than males.
3. Polar bears have 10 cm thick layer of blubber that keeps them well insulated from low temperature and cold water. Their dense and oily fur keeps them dry even after long time in the water.
4. They can swim 6 miles per hour. Some polar bears are seen 100 miles away from the shore. They can swim 70-100 miles at once.
5. Although they live in cold environment (temperature can drop below minus 45 degrees of Celsius), they can easily overheat when they run (due to thick fur and blubber).
6. They have incredible sense of smell and can sense seal on the ice that is 20 miles away.
7. Like all other bears, they are omnivores (eat both plants and meat). During summer season, bears like to eat berries.
8. Not all hunting attempts are successful and polar bear shows angry behavior when it loses its prey. Some researchers noted that polar bears break chunks of ice, kick snow or growl when they are disappointed.
9. They take good care about their hygiene and spend 15-20 minutes in grooming themselves after good meal.
10. Mating season is reserved for April and May. Female gives birth to 1-3 cubs in November or December. She takes care of them in a special “maternity dens” for three months. During that time, she doesn’t eat, drink or defecate.
Cubs stay with their mother until they reach two and half years. Polar bears are slow breeders; they have five litters maximally in a lifetime.
