sponges
This is an old revision of the document!
The Porifera, sponges, are sessile benthic invertebrates that represent one of the oldest, if not the oldest metazoan lineage. Sponges comprise approximately 8,500 described species divided among 4 classes and maintain numerous roles in the marine ecosystem such as nutrient cycling, habitat forming, and symbiosis with several different organisms. Bacteria comprise nearly 50% of the sponge biomass leading to five types of interactions (mutualism, commensalism…) and are formidable opponents in the battel for benthic space by filter feeding.
