Polar bears have a range of interesting adaptive and behavioral characteristics that help them survive out on the frozen tundra. While adaptations such as white fur and shorted limbs may be well known to most us, let us take a look at some of the lesser known characteristics of the lifetime of these bears.
Among the very fascinating behavioral adaptations is related to hunting. When the mother polar bear searches, the baby bears will freeze in a motion-less position so as to not frighten off any possible prey the mother bear might be hunting. Should the baby bears move, the mother bear will discipline them with a quick smack to the head. The baby bears usually get the message pretty quick after that.
Only the pregnant woman bears hibernate. Though hibernating females sleep soundly, they are easily and quickly awakened. The female bear’s heart rate will slow down to as little as 27 beats per minute from her usual rate of approximately 46 beats per minute. Most bears hibernate, however polar bears are the only bears that can give birth when hibernating.
Although adult bears weight up to inquire much as an incredible 600 pounds ( 272 kilograms ) the newly born cubs weight in at about just 1 pound ( a little under half a kilogram ). The cubs, when born, look hairless however they do infact have hair it’s just that their hair is extremely fine, providing them a bald look. One of the most surprising facts about the bears is their hair is not white at all! A polar bear’s fur only reflects light. The hair is truly hollow, representing the snow in their surroundings, the hollow hair also traps the sun’s heat to keep the bear warm. Their hair is also oily which permits them to shake of excess water after swimming.
All polar bears have padded paws with rough surfaces on their base. The rough surface of the pads help the bears to walk on ice and snow without slipping over. Their wide paws are also helpful for swimming. Their front paws are utilised to propel them through the water while the back legs and paws are used to steer. Another use they make of their paws would be to cover their muzzle (nose) when resting in order to conserve body heat. Their legs and paws are so powerful they can kill prey with a single blow.
Swimming The can swim in a normal rate of 6 mph. That equates to about 4.7 miles per hour. So the world’s fastest human swimmers would struggle to escape from a swimming polar bear! Not only that but they can cover a distance of 100 miles ( 161 kilometers ) in one swim.
One of the saddest facts about these bears is that many starve to death. Polar bears can live to about 25 years old however 70ï1/4…of polar bears don’t live to see their third birthday. There are a number of factors that contribute to this starting statistic include lack of their main food source – seals, pollution and oil spills from mining and a growing loss of habitat. A world without polar bears are a cold world really. For more information check out Atlantis Bat Removal.
