Polar Animals

Science · Polar Regions · conceptual

Know about other polar animals besides penguins and polar bears — seals that swim under ice, walruses with long tusks, Arctic foxes that turn white in winter, snowy owls, narwhals with their unicorn-like tusk, and whales that migrate to polar waters to feed — and that all these animals have special features to survive extreme cold

What mastery looks like

  • Name at least four polar animals beyond penguins and polar bears, such as seals, walruses, Arctic foxes, snowy owls, or narwhals
  • Describe one way each named animal survives the cold (e.g. walrus blubber, Arctic fox white winter coat)
  • State that narwhals have a long spiral tusk and live in Arctic waters

Check your understanding

Can Polar Animals name several animals that live in the freezing polar regions — like walruses, Arctic foxes, snowy owls, or narwhals — and explain how they cope with the cold?
