Polar bears
There are different types of animals that can only survive in the coolest places on the earth. Heard of polar bears? Arctic sea ice, water, islands, and continental coastlines around the Arctic Circle are dwelling place to these gigantic carnivores. The temperatures where these bears live ranges from an average -29°F/-34°C in winter and 32°F/0°C in summer. The coldest area in winter is northeastern Siberia, where the temperature has been recorded as low as -92°F/-69°C is not at all a place suitable for us but it is absolutely fine with these polar bears whose body is covered naturally with an extremely dense fur coat. Do you know what the favourite food of all these polar bears is? Seals. The polar bears spend a huge time moving great distances in search of their food. They can cover 20000 to 135000 square miles. They eat a lot in order to survive and develop a thick layer of fat which in turn helps them to keep themselves warm in such a chilly temperature. Another interesting fact about these guys is that they are excellent swimmers. They can swim for several hours and can hold their breath for about two minutes when they dive underwater. Male polar bears are called boars and female polar bears are called sows and their babies are called cubs.
