            Molluscs
          
        
        
          Slugs, snails, squids,
        
        
          and oysters, are
        
        
          molluscs. Some live
        
        
          on land and some
        
        
          live in water.
        
        
          
            Centipedes and millipedes
          
        
        
          If you try counting the legs on an
        
        
          insect and you find there are too
        
        
          many, the chances are you have
        
        
          found a centipede or millipede.
        
        
          They have lots and lots of legs.
        
        
          
            Crustaceans
          
        
        
          Most crustaceans, such as lobsters, crabs, and
        
        
          shrimps, live in water. Only the woodlouse
        
        
          lives on land. They often have a shell and
        
        
          their eyes are on stalks.
        
        
          
            Odd sea creatures
          
        
        
          The sea contains some
        
        
          very strange animals
        
        
          indeed. Here are a few:
        
        
          
            Sponge:
          
        
        
          these
        
        
          animals were once
        
        
          thought to be plants.
        
        
          Snails are
        
        
          found on land
        
        
          and in the sea.
        
        
          The octopus,
        
        
          which is also
        
        
          a mollusc, is a
        
        
          very intelligent
        
        
          creature.
        
        
          Centipedes have
        
        
          one pair of legs on
        
        
          each segment and
        
        
          millipedes have
        
        
          two pairs on each.
        
        
          
            Snail
          
        
        
          
            Lobster
          
        
        
          
            Centipede
          
        
        
          
            Centipede
          
        
        
          
            Millipede
          
        
        
          
            Starfish:
          
        
        
          most starfish
        
        
          have five arms to crawl
        
        
          across the sea floor.
        
        
          
            Anemone:
          
        
        
          these
        
        
          flower-like sea animals
        
        
          have no brains.
