Emperor Penguin (Aptenodytes forsteri) Birds (Aves)

Emperor Penguin

Near Threatened
Aptenodytes forsteri

The emperor penguin is the tallest and heaviest of all living penguin species. Living in the harshest winter environment on Earth, they breed during the Antarctic winter on sea ice. Females lay a single egg and immediately return to the ocean to feed, leaving the males to incubate the egg. Males balance the egg on their feet under a warm brood pouch for about 64 days, fasting through extreme winds and temperatures as low as -60°C.

Snow Leopard (Panthera uncia) Mammals

Snow Leopard

Vulnerable
Panthera uncia

The snow leopard, often called the 'ghost of the mountains', is a secretive big cat adapted to the cold, rugged mountain ranges of Central Asia. Equipped with thick fur and wide paws that act like snowshoes, they are solitary master climbers that navigate steep rocky slopes.

Polar Bear (Ursus maritimus) Mammals

Polar Bear

Vulnerable
Ursus maritimus

The polar bear is the largest land carnivore on Earth, native to the freezing regions of the Arctic Circle. Classed as marine mammals due to their reliance on sea ice, they are apex predators specialized in hunting seals. They are highly adapted to survive in extreme Arctic cold.

Atlantic Puffin (Fratercula arctica) Birds (Aves)

Atlantic Puffin

Vulnerable
Fratercula arctica

The Atlantic Puffin is a small, colorful seabird native to the cold waters of the North Atlantic. Known as the 'clown of the sea' due to its bright, parrot-like bill and expressive eyes, the puffin is a skilled diver. They spend the winter at sea and breed in large clifftop colonies in spring.

Snowy Owl (Bubo scandiacus) Birds (Aves)

Snowy Owl

Vulnerable
Bubo scandiacus

The Snowy Owl is a large, iconic owl species native to the open tundra of the Arctic. Recognizable by their white plumage and piercing yellow eyes, snowy owls are diurnal hunters that are active during the Arctic summer. They are nomadic birds that migrate south during harsh winters.

Narwhal (Monodon monoceros) Mammals

Narwhal

Least Concern
Monodon monoceros

Often called the 'Unicorn of the Sea', the Narwhal is a medium-sized toothed whale easily recognized by the long, spiral tusk protruding from its jaw, which is actually an overgrown tooth.

Reindeer (Caribou) (Rangifer tarandus) Mammals

Reindeer (Caribou)

Vulnerable
Rangifer tarandus

The Reindeer, known as Caribou in North America, is a species of deer adapted to extreme polar cold. They perform some of the longest overland migrations of any terrestrial mammal.

King Penguin (Aptenodytes patagonicus) Birds (Aves)

King Penguin

Least Concern
Aptenodytes patagonicus

The King Penguin is the second-largest penguin species. Living in massive colonies on sub-Antarctic islands, they are exceptional divers that hunt fish in cold pelagic waters.

Southern Rockhopper Penguin (Eudyptes chrysocome) Birds (Aves)

Southern Rockhopper Penguin

Vulnerable
Eudyptes chrysocome

The Rockhopper Penguin is one of the smallest crested penguins. Unlike other penguins that slide on ice, they jump across steep, slippery coastal rocks to reach nesting sites on high cliffs.

Gentoo Penguin (Pygoscelis papua) Birds (Aves)

Gentoo Penguin

Least Concern
Pygoscelis papua

The Gentoo Penguin is the third-largest penguin species and holds the title of the fastest underwater swimmer of all birds. They establish nesting colonies on rocky, ice-free beaches.

Beluga Whale (Delphinapterus leucas) Mammals

Beluga Whale

Least Concern
Delphinapterus leucas

Known as the 'Canary of the Sea' due to its high-pitched whistles and chirps, the Beluga Whale is an Arctic marine mammal. It is easily recognized by its pure white skin and bulbous, flexible forehead (melon).

Pacific Walrus (Odobenus rosmarus) Mammals

Pacific Walrus

Vulnerable
Odobenus rosmarus

The Walrus is a massive Arctic pinniped famous for its long ivory tusks, stiff facial whiskers (vibrissae), and wrinkled pink-brown hide. They use their tusks to pull themselves onto ice floes.

Macaroni Penguin (Eudyptes chrysolophus) Birds (Aves)

Macaroni Penguin

Vulnerable
Eudyptes chrysolophus

The Macaroni Penguin is the most numerous penguin species in the world, with over 18 million individuals. Named for the flamboyant yellow feather crests on their head, they nest in massive, noisy colonies.
