Why are there no polar bears in the North Pole?
For polar bears specifically, there was never a time in their evolutionary history when the North and South poles were connected by ice (or land, for that matter). People say polar bears are the "biggest terrestrial carnivore in the world, and yet they're not a terrestrial species at all," Derocher told Live Science.
Penguins spend 80% of their time in water and only go on land to mate. Penguins survive on fish that they catch in the ocean. The problem with the North pole is that its smack dab in the middle of a giant iceberg. There is no water in the north pole for them to hunt because the ice is so thick.
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).
Most polar bears occur north of the Arctic Circle to the North Pole. There are some populations south of the Arctic Circle in the Hudson Bay of Manitoba, Canada. Polar bears live in Alaska, Canada, Russia, Greenland, and some northern islands owned by Norway, such as Svalbard.
No one actually lives at the North Pole. Inuit people, who live in the nearby Arctic regions of Canada, Greenland, and Russia, have never made homes at the North Pole. The ice is constantly moving, making it nearly impossible to establish a permanent community.
It's likely since penguins won't move over large distances on land, they struggle to find new territory farther north. Any that do make it are likely either scared off by curious humans or killed by predators as they will make an easy meal for many land predators.
They evolved from a common ancestor of the brown bear (Ursus arctos) sometime between 5 million and 500,000 years ago, according to the expert. But even 5 million years ago, the continents were in similar positions to today, so polar bears never had the opportunity to travel from pole to pole.

Polar bears live in the Arctic, on ice-covered waters. Polar bears rely on sea ice to access the seals that are their primary source of food, as well as to rest and breed. The total polar bear population is divided into 19 units or subpopulations. Sixty percent of the sub-populations are in Canada.
What is the North Pole called?
Both the Arctic (North Pole) and the Antarctic (South Pole) are very cold because they get very little direct sunlight.
Polar bears (Ursus maritimus) typically need sea ice to survive, so the discovery is raising hopes that some members of the species might survive the loss of ice caused by climate change.
Have your little ones ever wondered, “Where does Santa Claus live?” He lives at the North Pole, of course! Santa stays at the North Pole year-round. It's where he trains the reindeer, shines his sleigh, ice fishes, tries Mrs. Claus' recipes and more.
You can meet Santa Claus and cross the magical Arctic Circle every day at Santa Claus Village in Rovaniemi in Lapland, Finland. Rovaniemi is the Official Hometown of Santa Claus in Lapland.
Unlike Antarctica, there's no land at the North Pole. Instead it's all ice that's floating on top of the Arctic Ocean. Over the past four decades, scientists have seen a steep decline in both the amount and thickness of Arctic sea ice during the summer and winter months.
All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the eight Arctic coastal states: Canada, Denmark (via Greenland), Finland, Iceland, Norway, Russia, Sweden and the United States. International law regulates this area as with other portions of Earth.
The first consistent, verified, and scientifically convincing attainment of the Pole was on 12 May 1926, by Norwegian explorer Roald Amundsen and his US sponsor Lincoln Ellsworth from the airship Norge.
There are five countries included in the range of polar bears. These are: Denmark (Greenland), Norway, Russia, the United States, and Canada. Within the United States, polar bears are only found within the state of Alaska.
Advertisement. Polar bears could be transported to the Antarctic, but they would almost certainly destroy the wildlife that is currently there and then die out themselves. In the Antarctic, penguins breed in large numbers and have no land-based predators.
This works because they are threatened by very few (if any) land predators. While penguins are vulnerable to skuas and giant petrels flying overhead, in the north they would have fallen prey to foxes, wolves, polar bears – maybe even humans!
Why don't we put polar bears to Antarctica?
It would be extremely reckless to try to introduce polar bears into the Antarctic in order to save them from extinction. The Antarctic species that the bears would be likely to prey upon have evolved no defences to polar bear predation and would be likely to suffer catastrophic losses.
If polar bears are given sturdy ground, might they learn to survive? 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. For one, Antarctica is largely lacking in land predators similar to the polar bear.
“Arctic” comes from the Greek arktos, “bear,” because the constellation Ursa Major, “the greater she-bear” (also known as the Big Dipper), is always visible in the northern polar sky. “Antarctic,” then, means “opposite the bear.”
As global warming melts away Arctic sea ice, polar bears are scrambling to find ice on which to hunt. But Greenland's fjords harbor a small but unique group of polar bears that rely on glacial ice. Greenland's fjords harbor a unique group of polar bears that rely on glacial ice, a NASA-funded study reports in Science.
