12 Arctic Animals That Stay Warm (and Adorable) in Subzero Temperatures

Polar bears dominate the Arctic food web as a powerful apex predator. Their black skin absorbs sunlight while thick fur and fat insulate them against brutal Arctic winter temperatures.

They roam sea ice and ice floes across the Arctic Ocean searching for their primary food source: ringed seal and bearded seal. As climate change causes sea ice to shrink, these Arctic animals must swim longer distances between hunting grounds.

The Arctic wolf survives in the high Arctic where few other predators live. These wolves roam remote land masses across the far north including northern Greenland and the Canadian Arctic.

Unlike gray wolves farther south, Arctic wolves depend on prey such as wild reindeer, musk oxen, and Arctic hare. Their dense coat allows them to withstand extreme environments where winter temperatures plunge well below minus 40 degrees Fahrenheit (minus 40 degrees Celsius).

Musk oxen look like shaggy relics from the Ice Age. Their long outer hair—called guard hair—drapes almost to the ground and protects a dense undercoat that traps heat.

These plant eaters graze tundra grasses across Baffin Island and other parts of the Arctic region during the short summer months. When predators approach, the herd forms a defensive circle with horns facing outward.

The Arctic fox survives winter by switching coats. In winter its fur can turn bright-white to blend into snow across the tundra. During warmer months the coat can shift to brown or gray.

These clever hunters eat small mammals, bird eggs, and leftovers from larger predators. Their thick fur covers even their paws, allowing them to walk across pack ice without losing body heat.

The Arctic hare resembles a snowball with legs. This species lives in the high Arctic of Canada and Greenland where snow can blanket the tundra most of the year.

Arctic hares feed on woody plants and moss hidden beneath snow. They rely on speed and camouflage to avoid predators like Arctic wolf and snowy owls.

Beluga whales are among the most recognizable marine mammals in cold Arctic waters. Their white bodies blend with drifting sea ice.

These whales produce a huge range of vocal sounds, earning them the nickname "canaries of the sea." Pods migrate along coastal areas each year.

Bowhead whales rank among the longest-living mammals on Earth. Scientists have discovered individuals more than 200 years old.

These giants push through thick pack ice using massive skulls. They filter plankton from cold Arctic waters and migrate seasonally.

The Greenland shark lurks deep in the Arctic Ocean. This slow-moving predator grows extremely slowly and may live for centuries.

Researchers studying these sharks estimated that some individuals may be close to 400 years old. They feed on fish, seals, and other animals in dark, icy water.

Snowy owls patrol the tundra for small mammals such as lemmings. Their white feathers provide camouflage against snow-covered landscapes.

During years when prey becomes scarce, these birds travel south beyond the Arctic Circle. In strong prey years they nest at higher densities across the tundra.

Arctic terns complete one of the longest migrations on Earth. These bird species travel from the Arctic to Antarctica and back every year.

Their migratory patterns allow them to experience two summers each year. During late summer in the Arctic, they gather along coastal areas and feed on fish in cold Arctic waters.

Yellow-billed loons breed in remote tundra lakes across Alaska and northern Canada. These large diving birds hunt fish and crustaceans.

They nest on tundra lakes during the short Arctic summer while the ice recedes. After the breeding season they migrate south to spend winter on the open ocean.

Puffins nest in colonies along cliffs in places like the Faroe Islands and the Svalbard archipelago. Their colorful bills stand out against dark feathers.

These seabirds dive into cold waters to catch fish. Their playful nature and clumsy walk on land make them favorites among intrepid explorers visiting the Arctic on expedition cruise ships.

Arctic peoples have lived alongside these animals for thousands of years. Today human activity, habitat loss, and climate change are reshaping wildlife habitats across the far north.

Travelers who take an Arctic cruise sometimes witness these species under the glow of the northern lights—also known as the aurora borealis—dancing across the sky above the North Pole.
