WebIntroduction. The phylum Porifera, known as sponges, is a highly important metazoan, playing roles in three main areas: (a) impacts on the substrate (provoking bio-erosion, building and stabilizing reefs, and consolidating and regenerating the benthos substrate), (b) bentho-pelagic coupling (interfering in carbon, silicon, oxygen, and nitrogen cycles and … Web1 Jan 2003 · The implications of such variations in sponge taxonomy may be important.
