Why polar bears are not found in south Pole?
Polar bears live on north pole in arctic region and south pole (antarctic region) is inhabited by penguins. Since both the places are cold. polar bear can easily survive if they move to south pole but this might create problem for penguins staying there as polar bear will start feeding on penguins.
Polar bears live in the frozen Arctic landscape, the northernmost point on the planet. They are not found in Antarctica, even though the North and South poles are both snow-covered, icy-cold environments. Polar bears range across the Arctic Ocean, in parts of Canada, Alaska, Russia, Greenland and Norway (Svalbard).
For millions of years, polar bears have called the Arctic circle home. Polar bears evolved from a population of brown bears and adapted to Arctic conditions in order to thrive. Some polar bears will leave the Arctic circle to explore other subArctic climates in northern Canada, Alaska, Russia, Norway, and Greenland.
The farthest south that polar bears live all year round is James Bay in Canada, which is about the same latitude as London, England. During winter, when the polar ice pack extends further south, polar bears move as far south as Newfoundland and into the northern Bering Sea.
A “hidden world” discovered under the ice in Antarctica
He and other New Zealand scientists have just discovered an underwater ecosystem 500 metres under the Antarctic ice, in an estuary hundreds of kilometres from the edge of the Ross Ice Shelf, the largest ice barrier on the white continent.
Antarctica is isolated
However, Antarctica has been separated from other continents by the vast Southern Ocean for about 45 million years – since before bears evolved. While polar bears are excellent swimmers, they would struggle to migrate to Antarctica.

-Krill provide the main diet for the other animals. -Need to emphasize that life forms of the Arctic are not necessarily found in the Antarctic, specifically polar bear, reindeer, wolves, and moose.
Antarctica's wildlife is diverse and unique. It is the only continent on Earth which has no terrestrial mammals, but is home to a range of marine wildlife and birds, including penguins! The most common birds in Antarctica are penguins. It is home to 18 different species, including the Emperor Penguin.
Antarctica is the only continent with no permanent human habitation. There are, however, permanent human settlements, where scientists and support staff live for part of the year on a rotating basis. The continent of Antarctica makes up most of the Antarctic region.
Could a polar bear survive in Antarctica?
While it's true that the Antarctic has an appropriate climate for polar bears and food for them to eat, relocating the bears south is far from foolproof.
However, grizzly bears are tougher than polar bears as they possess stronger and longer claws and an elongated skull with sharp and long canines that can completely separate the flesh from bone.
A grizzly bear is likely able to beat both a polar bear and a black bear in a battle for survival.
Background On Polar Bears
Polar bears are the world's largest bear species and massive land-based carnivores, despite spending most of their lives near water and ice. And although the Arctic and Antarctica ecosystems are similar in many ways, only the Arctic is home to polar bears.
The rough weather conditions and low visibility make it extremely difficult to fly and land a plane over the continent. It is technically possible to fly to Antarctica, but there are very few flights that take the risk of going there.
A few years ago, a giant hole opened up in the Antarctic sea ice, capturing attention around the world. Not since the 1970s had such a chasm appeared in the mid-ocean ice of the Weddell Sea. Scientists showed in previous research that ocean processes and cyclones contributed to the hole, called a polynya.
Antarctica is the only continent with no native population. There is still no permanent human settlement, due to the unforgiving climate and terrain, although a few thousand people are located there on a temporary basis at one of the many research stations.
It has no natural predators and knows no fear of humans, making it an extremely dangerous animal.
What makes the South Pole so much colder than the North Pole is that it sits on top of a very thick ice sheet, which itself sits on a continent. The surface of the ice sheet at the South Pole is more than 9,000 feet in elevation--more than a mile and a half above sea level.
The people who travel to or live in Antarctica fall into two main groups, those who live and work on scientific research stations or bases, and tourists. No-one lives in Antarctica indefinitely in the way that they do in the rest of the world. It has no commercial industries, no towns or cities, no permanent residents.
Why can't we go to the South Pole?
Due to harsh conditions, extreme weather and no permanent population on the continent there are no regular passenger flights to Antarctica. Most flights transport research personnel and supply the bases. The lack of infrastructure makes it difficult to recover a stranded aircraft in case of an emergency.
People from all over the world undertake research in Antarctica, but Antarctica is not owned by any one nation. Antarctica is governed internationally through the Antarctic Treaty system. The Antarctic Treaty was signed in 1959 by 12 countries who had scientists in and around Antarctica at the time.
Even though the North Pole and South Pole are "polar opposites," they both get the same amount of sunlight. But the South Pole is a lot colder than the North Pole.
As omnivores, bears often carry the larvae of a nasty parasite, Trichina spiralis. Eating undercooked bear meat can cause trichinosis, which can cause severe sickness or even death in humans. That's why bear is most often cooked in stews, chilis, braises, or in well-cooked sausage.
LIFE CYCLE: Polar bears can live up to 25 or 30 years in the wild. FEEDING: The top Arctic predators, polar bears primarily eat ringed seals but also hunt bearded seals, walrus, and beluga whales, and will scavenge on beached carrion such as whale, walrus, and seal carcasses found along the coast.
