The Arctic fox, often referred to as the “white fox,” thrives in the frigid landscapes of the Arctic and subarctic regions. Their remarkable adaptations include a warm, thick fur coat that changes color with the seasons, providing camouflage in snow-covered environments. 

These resourceful omnivores have a varied diet, consuming small mammals, birds, fish, and even carrion. They are well-equipped to endure the harsh Arctic winters, using their dens as shelters against the biting cold. With their small size and adaptability, Arctic foxes are agile hunters, making them essential components of the Arctic food web.

Walrus (Odobenus rosmarus):

Walruses, characterized by their prominent tusks and distinctive whiskers, are marine mammals that inhabit the icy waters of the Arctic and subarctic regions. These sociable creatures use sea ice as resting platforms and haul-out sites, congregating in large numbers. Walruses primarily feed on benthic invertebrates like clams and snails, which they extract from the seafloor using their sensitive whiskers and powerful tusks. 

These tusks also aid in hauling themselves out of the water onto ice floes. Walruses play a crucial role in shaping the Arctic ecosystem, and their conservation is imperative as they face habitat loss and other threats due to climate change.

Seals (Various species):

Seals, including the ringed seal, bearded seal, and Weddell seal, are marine mammals that rely on icy environments for various aspects of their life cycles. They are well-adapted to cold waters and use sea ice as a platform for giving birth, molting, and resting. Seals have specialized limbs and bodies for efficient swimming, with some species possessing adaptations for moving on ice. 

These animals are also the primary prey of polar bears and play a significant role in Arctic food webs. Ringed seals, in particular, create and maintain breathing holes in the ice, essential for their survival and that of other Arctic species.

Beluga Whale (Delphinapterus leucas):
