    • ‘These include representatives of the Porifera, Mollusca, and possibly Arthropoda and Annelida or Pogonophora.’
    • ‘Both the frenulate pogonophoran clade and the vestimentiferan clade have been referred to as phyla, classes within the Annelida, classes within the Pogonophora, and subclasses within class Pogonophora within the Annelida.’
    • ‘Another phylum, the Pogonophora, are also vermiform animals with a trochophore larva.’
