Most other taxonomists think there are somewhere in the thirties in the realm of 'How many phyla are there ?' Some invertebrate animal phyla are: Phylum Porifera, Phylum Cnidaria, Phylum Ctenophora, Phylum Platyhelminthes, Phylum Annelida, Phylum Mollusca, Phylum Arthropoda, Phylum Echinodermata, Phylum Hemichordata, Phylum Nematoda, Phylum Rotifera, Phylum Kinorhyncha, Phylum Nemertea, Phylum Bryozoa
