            Birds
          
        
        
          All birds have wings,
        
        
          and most (but not all)
        
        
          can fly. They have
        
        
          feathers and a beak.
        
        
          Baby birds hatch
        
        
          from eggs.
        
        
          
            Fish
          
        
        
          Fish need to live
        
        
          in water. They
        
        
          breathe through
        
        
          gills, and most
        
        
          are covered in
        
        
          scales. Fish use
        
        
          their fins to move
        
        
          through water.
        
        
          
            Insects
          
        
        
          There are more types of insect
        
        
          on Earth than any other
        
        
          animal. Insects can live almost
        
        
          anywhere. They have six legs
        
        
          and bodies with three sections.
        
        
          
            Spineless creatures
          
        
        
          Animals without
        
        
          backbones are called
        
        
          invertebrates. There
        
        
          are several types of
        
        
          invertebrates.

            Amphibians
          
        
        
          Amphibians live both
        
        
          in water and on land.
        
        
          They usually have
        
        
          slimy skin. Baby
        
        
          amphibians hatch
        
        
          from jelly-like eggs.

          are part
        
        
          of an invertebrate group
        
        
          called gastropods.

          soft bodies and no legs.
        
        
          They like damp areas.
        
        
          
            Jellyfish, starfish, and
          
        
        
          
            sponges
          
        
        
          are invertebrates
        
        
          that live in water.
