          Arctic animals
        
        
          have to endure
        
        
          bitterly cold
        
        
          weather. Walruses
        
        
          have a layer of
        
        
          blubber (fat) to keep
        
        
          them warm. Polar
        
        
          bears and reindeer
        
        
          have thick coats of fur.

          The Arctic tern spends
        
        
          most of its life flying.
        
        
          It breeds in the Arctic
        
        
          during the northern
        
        
          summer. Then it flies
        
        
          all the way to the
        
        
          Antarctic, where it
        
        
          stays during the
        
        
          southern summer.

          The Arctic tern catches small
        
        
          fish and shrimps by swooping
        
        
          across the surface of the sea.
