The Arctic is one of the most extreme environments on Earth, yet it’s home to some of the most resilient and fascinating creatures found nowhere else in the world.
North America’s Arctic region supports life perfectly adapted to its frigid challenges. These unique animals embody the spirit of endurance and ingenuity that defines the far north, offering a glimpse into one of nature’s most remarkable ecosystems.
This article is for general knowledge only and is based on information from online sources. Wildlife behaviour and habitat ranges may vary due to climate change and environmental factors. Always respect local guidelines and avoid disturbing animals in their natural habitats.
1. Polar Bear

With paws the size of dinner plates, polar bears reign as the Arctic’s apex predator. These magnificent carnivores spend most of their lives on sea ice, hunting seals and traveling vast distances across frozen landscapes.
Their thick white fur and black skin underneath help them absorb heat while staying camouflaged. Males can weigh up to 700 kilograms, making them the largest land carnivores in North America.
Climate change poses serious threats to their habitat as sea ice continues to diminish each year. Conservation efforts focus on protecting their hunting grounds and monitoring population health across Canadian territories and Alaska.
2. Arctic Fox

Wrapped in the warmest fur of any mammal, Arctic foxes thrive where temperatures plummet to bone-chilling extremes. Their coats change colour with the seasons, shifting from pristine white in winter to brown or grey during summer months.
These clever hunters follow polar bears to scavenge leftovers and cache food during abundant times. Their compact bodies and short ears minimize heat loss in frigid conditions.
Arctic foxes can survive temperatures as low as minus 70 degrees Celsius without shivering. Small but mighty, they represent nature’s brilliant adaptation to extreme cold throughout northern Canada and Alaska.
3. Muskox

Looking like prehistoric survivors, muskoxen have roamed Arctic landscapes for thousands of years. Their long, shaggy coats called qiviut provide exceptional insulation, keeping them warm during brutal winter storms.
When threatened, these herd animals form defensive circles with their horns facing outward to protect vulnerable calves. Both males and females sport curved horns that meet at the centre of their foreheads.
Muskoxen graze on Arctic vegetation like grasses, willows, and sedges throughout the year. Their ability to withstand extreme cold makes them perfectly suited for life in Canada’s northern territories and parts of Alaska.
4. Narwhal

Often called the unicorns of the sea, narwhals possess one of nature’s most distinctive features. The males grow a spiral tusk that can reach three metres long, actually an elongated tooth filled with sensitive nerve endings.
These medium-sized whales travel in pods through Arctic waters, using echolocation to navigate beneath ice-covered seas. Scientists believe the tusk helps males sense environmental changes and may play a role in mating rituals.
Narwhals feed primarily on Arctic cod, Greenland halibut, and squid during deep dives. Found exclusively in Canadian and Greenlandic Arctic waters, these mysterious mammals remain one of the least understood whale species.
5. Snowy Owl

Ghostly white feathers make snowy owls perfectly camouflaged against snow-covered tundra. Unlike most owl species, these diurnal hunters actively search for prey during daylight hours, which suits the Arctic’s extended summer days.
Their diet consists mainly of lemmings, though they’ll catch other small mammals and birds when necessary. Females tend to have more dark markings than males, who appear almost pure white.
Thick feathering covers their legs and feet, protecting them from frostbite during harsh winters. These powerful fliers breed in the Arctic tundra of Canada and Alaska, occasionally migrating south when food becomes scarce.
6. Beluga Whale

Nicknamed the canaries of the sea for their vocal nature, beluga whales communicate through clicks, whistles, and chirps. Their flexible necks allow them to turn their heads in all directions, unlike most whale species with fused vertebrae.
The distinctive white colouration develops as they mature, with calves born grey or brown. Their rounded foreheads, called melons, help focus sound for echolocation in murky Arctic waters.
Belugas feed on fish, squid, and crustaceans found along the seafloor and in open water. These social mammals gather in large pods throughout Canadian Arctic waters, particularly in Hudson Bay and the St. Lawrence estuary.
7. Caribou (Barren-Ground)

Embarking on one of nature’s longest land migrations, barren-ground caribou travel up to 5,000 kilometres annually. Both males and females grow antlers, unusual among deer species, which they use to dig through snow to reach vegetation.
Their wide, flat hooves act like snowshoes, distributing weight across soft snow and boggy summer tundra. Special tendons in their feet create clicking sounds as they walk, helping herds stay together in blizzards.
These resilient herbivores survive on lichens, grasses, and shrubs throughout Canada’s northern territories. Indigenous peoples have depended on caribou for food, clothing, and tools for thousands of years.
8. Arctic Hare

Built like miniature snowmobiles, Arctic hares possess powerful hind legs that propel them across frozen landscapes at speeds reaching 60 kilometres per hour. Their compact ears reduce heat loss while their thick white winter coats provide excellent camouflage against predators.
Unlike their southern cousins, these hares often remain white year-round in the far north. They dig through snow to find woody plants, mosses, and lichens for food.
Arctic hares sometimes gather in groups of hundreds, huddling together for warmth during severe weather. Found throughout Canada’s Arctic islands and mainland tundra, they’ve adapted remarkably well to life in freezing conditions.
9. Wolverine

Pound for pound, wolverines rank among the toughest animals in the Arctic. These muscular members of the weasel family possess incredible strength, capable of taking down prey much larger than themselves.
Their thick, oily fur resists frost and water, making it highly valued for parka trim in extreme cold. Wolverines cover enormous territories, sometimes traveling 25 kilometres in a single day while searching for food.
They scavenge carrion but also hunt live prey including rabbits and even young caribou. Solitary and elusive, wolverines inhabit boreal forests and tundra across northern Canada and Alaska, avoiding human contact whenever possible.
10. Ringed Seal

As the smallest and most abundant Arctic seal species, ringed seals form the foundation of the polar bear’s diet. Their name comes from the light-coloured circular patterns scattered across their grey backs.
These resourceful seals maintain breathing holes in sea ice using their strong claws, sometimes keeping several open throughout their territory. They give birth in snow caves above the ice, protecting pups from harsh weather and predators.
Ringed seals dive deep to catch Arctic cod, shrimp, and other small marine creatures. Found throughout Arctic waters surrounding Canada and Alaska, they’ve adapted perfectly to life in ice-covered seas year-round.
11. Arctic Ground Squirrel

Masters of hibernation, Arctic ground squirrels can lower their body temperature below freezing, entering the deepest hibernation state of any mammal. They spend up to eight months underground, surviving on fat reserves accumulated during brief summer months.
Their high-pitched alarm calls warn colony members of approaching predators like foxes and hawks. These industrious rodents gather seeds, roots, and vegetation, storing food in extensive burrow systems.
During active months, they must eat constantly to build sufficient fat stores for winter survival. Arctic ground squirrels inhabit tundra regions across Alaska and northwestern Canada, playing important roles in Arctic food webs.
12. Peary Caribou

Named after Arctic explorer Robert Peary, these caribou represent the smallest and palest subspecies in North America. Their light-coloured coats help them blend into the stark landscapes of Canada’s high Arctic islands.
Peary caribou face unique challenges, including unpredictable ice conditions that sometimes prevent access to feeding grounds. They survive on sparse vegetation like Arctic willow, grasses, and sedges scattered across barren terrain.
Population numbers have declined significantly due to climate change and habitat disruption. Listed as endangered, Peary caribou now receive protection and monitoring throughout their range on islands including Ellesmere, Devon, and Banks in Canada’s Arctic archipelago.
