- - - - acting as pollinators
      - a food source for wildlife
      - dispose of wastes and remains
    - - distinct head, thorax, abdomen
        
        head has two compound eyes
        
        digestive organs and sex organs located in abdomen
        
        (in winged insects) thorax has one or two pairs of wings
- - - - Vertebrates...
        
        were first jawless fishes, later evolving jaws
      - Tetrapods...
        
        have four bony limbs that descended from a four-limbed ancestor
        
        gave rise to
      - -->
      - Amniotes...
        
        have specialized eggs and other adaptations to dry habitats
- - - - Asymmetry aka Radial Symmetry
        
        examples are...
        
        Jellies, sea anemones,
        other cnidarians
      - Symmetry aka Bilateral Symmetry...
        
        examples are...
        
        worms, snails, lobsters
        
        have two different lineages
        
        protostomes (first opening becomes mouth)
        
        deuterostomes (second opening becomes mouth), also has lineages in vertebrates
        
        have variations in body cavities
        
        coelom (e.g., most bilateral animals)
        
        no cavity (e.g., flatworm)
        
        pseudocoelom (e.g., roundworms)
    - - annelids
