    • chordates
      • most are vertebrates
      • have hard, internal skeleton
      • fish
        • cold blooded
        • gills and scales
        • example: catfish
      • amphibians
        • moist skin
        • jelly covered eggs
        • 4 limbs
      • reptiles
        • dry and scaly skin
        • lungs for gas exchange
        • example: snakes
      • birds
        • feathers
        • warm blooded
        • internal fertillisation
      • mammals
        • nipples
        • feed young with milk from mammary glands
        • example: elephants
    • annelids
      • body covered in mucus to conserve water
      • many are hermaphrodite

    • nematodes
      • no segments
      • long cylindrical body
      • body covered in mucus
      • long muscles
    • arthropods
      • uses the resources in their habitat to the maximum
      • show interesting adaptation in their life cycle
      • cructaceans
