 FACT: When Mr. Ray sings his "Lets Name the Species" song, he isnt  actually naming species. Porifera, Coelenterata, Ctenophora,  Bryozoa, Arthropoda, Echinodermata, and Chordata are all phyla.  Hydrozoa, Scyphozoa, and Anthozoa are classes in the phylum Cnidaria  (Coelenterata), and Gastropoda is a class in the phylum Mollusca.  The order of classification is: kingdom, phylum, class, order,  family, genus, species. Phyla and classes are definitely not the  same as species.
