      - insects
        
        3 pairs of legs
        
        they can have 1 or 2 pairs of wings (not all of them have)
        
        they go through metamorphosis
      - myriapods
        
        they are segmented
        
        millipeds
        
        2 pairs of legs per segment
        
        centipeds
        
        1 pair of legs per segment
        
        they are terrestrial
    - - they have segmented bodies divided into

        thorax

        they use their foot to move around
        
        they are herbivores
      - bivalves

        the shell is made up of two parts (valves)
        
        they fix themselves to a solid surface
      - cephalopods
        
        they use their tentacles to capture their prey
        
        they are carnivores
        
        their sheed has evolved into a long, thin piece (gladius)
        
        they have tentacles (instead of a foot)
    - - the mayority are marine
      - their bodies are soft
      - they have a vascular foot
      - they are not divided into rings
      - some of them produce a protective external shell
