          Amphibians are different
        
        
          from reptiles in that they
        
        
          have smooth skin with no
        
        
          scales. They are born in
        
        
          water then live on land
        
        
          or in water when
        
        
          they grow up.
        
        
          
            Colourful creatures
          
        
        
          Many amphibians are incredibly
        
        
          colourful creatures. Some are
        
        
          spotted, others are striped and
        
        
          some are just very bright.
        
        
          
            Amazing skin
          
        
        
          Most adult amphibians, such as this
        
        
          salamander, can breathe through
        
        
          their skin as well as their lungs.
        
        
          In order for the skin to
        
        
          breathe it has to be kept
        
        
          moist, which is why
        
        
          most amphibians
        
        
          like to live
        
        
          near water.
