The animal phyla are as listed: Porifera , Cnidaria , Ctenophora , Platyhelminthes , Nemertea , Rotifer , Nematoda , Mollusca , Annelida , Arthropoda , Lophophorates, Echinodermata , and Chordata . This guide will only go over the bolded phyla as those are the ones that taxonomists are most sure about regarding their placements/ existence.
