- THE ARTIC FOX Arctic foxes have several adaptations that allow them to survive. Their round, compact bodies minimize surface area that is exposed to the cold air. Their muzzle, ears, and legs are short, which also conserves heat. ... Arctic foxes also have thick fur on their paws, which allows them to walk on both snow and ice.
- Polar bears depend on the frozen ocean to hunt for their main sources of food: seals and walrus. ... For one, Antarctica is largely lacking in land predators similar to the polar bear. Without these types of predators, penguins and seals have evolved to be rather confident when hanging out above the water.
- They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather. They also huddle together with their friends to keep warm. ... Waterproofing is critical to penguins' survival in water, Antarctic seas may be as cold as -2.2°C (28°F) and rarely get above +2°C (35.6°F).
- A glacier is a huge mass of ice that moves slowly over land. The term “glacier” comes from the French word glace (glah-SAY), which means ice. Glaciers are often called “rivers of ice.” Glaciers fall into two groups: alpine glaciers and ice sheets.
- An Igloo (a place for people to stay warm and dry) made from blocks of snow placed on top of each other, often in the shape of a dome (like half of a hollow ball). ... Snow is used because the air pockets trapped in it make it an insulator.
- The aurora australis or southern lights is a natural light display in the Earth's sky. It is the southern cousin to the aurora borealis. The aurora australis is visible from high southern latitudes in Antarctica The activity that creates auroras begins on the sun.
