- - - - Phylum: Syndermata
        Clades: Rotifera, acanthocephala
        Descriptions: Hemocoel, rotifer have alimentary canal, jaws, acanthocephalans
      - Phylum: Ectoprocta and Brachiopoda
        Clades: phylactolaemata, gymnolaemata, stenolaemata
        Description: Coelom, have lophophores
      - Phylum: Mollusca
        Clades: Polyplacophora, gastropoda, scaphopoda, monoplacophora, polyplacophora
        Description: Hemocoel, three body parts(muscular foot, visceral mass, mantle), most have hard shell made of calcium
      - Phylum: Annelida
        Clades: Polychaeta, oligochaeta, hirudinea
        Description: Coelom, body wall and internal organs are segmented.
      - Lophotrochozoan
      - The Lophotrochozoa is a major clade of protostome animals comprising several phyla. Platyhelminthes (flatworms) are bilaterally symmetrical, acoelomate, and dorsoventrally flattened. Mollusca are coelomates with a three-part body plan. Syndermata, including rotifers, also have a defined body cavity. The Ectoprocta and Brachiopoda are coelomate phyla. Annelida (segmented worms) are coelomates characterized by body segmentation. As a group, these phyla first appeared and diversified during the Cambrian Period of the Paleozoic Era
    - - Phylum: Arthropoda
        Clades: Chelicerata, myriapods, crustaceans, Hexapoda
        Descriptions: Hemocoel, reduced coelom, have segmented body, jointed appendages, and exoskeleton made protein and chitin
      - The ecdysozoans are a major animal clade defined by the process of molting (ecdysis). This group includes Phylum Nematoda (roundworms), which are bilaterally symmetrical, have a hemocoel body cavity, and possess a simple cylindrical body with no circulatory system. It also includes the highly diverse Phylum Arthropoda, which are bilaterally symmetrical with a hemocoel and reduced coelom, and are characterized by their segmented body, jointed appendages, and hard chitin-protein exoskeleton. Both of these phyla first evolved and underwent their initial diversification during the Cambrian Period of the Paleozoic Era.
