Arctic and polar animals survive in some of the coldest places on Earth. They include land mammals, marine mammals, seabirds, fish, penguins, and many smaller creatures found across the Arctic, Antarctica, tundra, sea ice, and polar oceans.
The Arctic surrounds the North Pole, while Antarctica surrounds the South Pole. Some animals live in one polar region only, while others occur in cold oceans across a much wider range. Learning their names by group makes them easier to recognize, remember, and use correctly in English.
Arctic and Polar Animal Names
Arctic and polar animals are animals adapted to cold northern or southern regions, including frozen land, tundra, pack ice, coastal waters, and polar seas. Their adaptations may include thick fur, dense feathers, insulating fat, seasonal coats, or behaviors that reduce heat loss.

Most Common Arctic and Polar Animals
These are some of the best-known animals associated with the Arctic, Antarctica, and their surrounding cold oceans.
Polar Bear
The polar bear is a large Arctic predator found around the North Pole. Its thick fur and layer of body fat help protect it from extreme cold. Polar bears mainly hunt seals from sea ice. They do not naturally live in Antarctica.
Arctic Fox
The Arctic fox is a small fox adapted to tundra environments. Many have white winter coats that provide camouflage against snow. Their fur becomes thinner and often brown or gray during warmer months. Arctic foxes eat small mammals, birds, eggs, fish, and carrion.
Reindeer
Reindeer, also called caribou in North America, live across Arctic and subarctic regions. Their wide hooves help them move over snow and soft tundra ground. Both males and females can grow antlers. Many populations travel long distances during seasonal migrations.
Musk Ox
The musk ox is a heavy Arctic mammal with a long, shaggy coat. Beneath its outer hair is a fine insulating layer called qiviut. Musk oxen mainly eat grasses, sedges, and other tundra plants. They often form defensive groups when threatened.
Walrus
The walrus is a large marine mammal recognized by its tusks, whiskers, and thick body. It lives in Arctic coastal waters and around sea ice. Walruses mainly feed on clams and other animals from the seafloor. Their tusks can help them move onto ice and defend themselves.
Ringed Seal
The ringed seal is one of the most widespread seals in the Arctic. It maintains breathing holes in sea ice using the claws on its front flippers. Fish and small marine animals form much of its diet. Ringed seals are an important prey species for polar bears.
Harp Seal
Harp seals live mainly in the North Atlantic and Arctic waters. Young pups are famous for their pale coats, although their appearance changes as they mature. Adults eat fish and marine invertebrates. Large groups gather on ice during the breeding season.
Bowhead Whale
The bowhead whale is strongly associated with Arctic and subarctic seas. It has a massive head that can help it break through relatively thin sea ice. Bowheads filter tiny animals from seawater using baleen. They are among the longest-lived mammals known.
Beluga Whale
The beluga is a white whale found in Arctic and subarctic waters. Adults have distinctive pale skin and a rounded forehead called a melon. Belugas are highly vocal and use many clicks, whistles, and other sounds. They eat fish, squid, and crustaceans.
Narwhal
The narwhal is an Arctic whale best known for its long spiral tusk. The tusk is actually an enlarged tooth and is most commonly seen in males. Narwhals live around Greenland, Canada, and other high-Arctic waters. They feed on fish, squid, and other marine prey.
Orca
The orca, or killer whale, occurs in oceans around the world, including polar waters. Different populations may specialize in different prey such as fish, seals, or other marine mammals. Orcas live in social family groups. Their black-and-white markings make them easy to recognize.
Emperor Penguin
The emperor penguin is the largest living penguin species. It breeds on Antarctic sea ice during the extremely cold winter. Adults take turns protecting eggs and traveling to sea for food. Their diet includes fish, squid, and krill.
Adélie Penguin
Adélie penguins live around the Antarctic coast and nearby islands. They have black-and-white plumage and a noticeable white ring around each eye. These penguins feed mainly on krill and small fish. They build nests from small stones.
Leopard Seal
The leopard seal is a large Antarctic seal with a long body and powerful jaws. It eats krill, fish, squid, seabirds, and sometimes penguins or other seals. Leopard seals spend much of their time around pack ice. They are strong and agile swimmers.
Weddell Seal
The Weddell seal lives farther south than most other mammals. It can remain underwater for long periods while searching for fish and other prey. These seals use their teeth to maintain breathing holes in Antarctic ice. They often rest on fast ice near the coast.

FAQs
Arctic and polar animals are species living in cold northern or southern regions, including tundra, sea ice, polar coasts, and surrounding oceans.
Common Arctic animals include polar bears, Arctic foxes, reindeer, musk oxen, walruses, ringed seals, narwhals, belugas, snowy owls, and Arctic terns.
Antarctica supports emperor and Adélie penguins, Weddell seals, leopard seals, crabeater seals, Antarctic petrels, krill, whales, fish, and other marine species.
No. Polar bears naturally live in the Arctic, while wild penguins occur in the Southern Hemisphere, including Antarctica and nearby subantarctic regions.
The blue whale is the largest known animal on Earth and feeds in productive cold waters, including parts of the Arctic and Southern Ocean.
Polar bears, ringed seals, bearded seals, walruses, and several seabirds regularly use Arctic sea ice for hunting, resting, breeding, or avoiding predators.
Their diets vary widely. Polar animals may eat fish, seals, krill, squid, shellfish, birds, eggs, grasses, sedges, lichens, or other tundra plants.
No. White coloring helps some species with camouflage, but many polar animals are black, brown, gray, patterned, or brightly marked instead.
