I use the term spongiomorph because anatomical, biochemical, and genetic evidences reveal that the group of organisms that we all learned as Phylum Porifera is, in fact, a paraphyletic group; our living sponges are relicts of a radiation of erect water-filterers, an initial diversification of metazoans into a colonial lifestyle.
