An area dominated by sponges, simple multicellular animals of the Phylum Porifera that live attached to the seafloor. Their soft and porus body structure is supported by a framework of fibrous proteins, and spicules of calcium carbonate or silica. Sponges are morphologically diverse, but all draw in a current of water using specialised flagella and extract nutrients and oxygen from the flow.
