Which of these predators lives only in the frozen Arctic landscape?

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). They can walk on ice or swim long distances to find food or breed – sometimes roaming across vast areas. Polar bears have a strong cultural significance for Arctic people, and beyond, polar bears are top predators in their food web. Which means they play a vital role in the balance of their ecosystem.
