"Poriferans" is the scientific term for sponges, members of the animal phylum Porifera, which means "pore-bearer" in Greek. Sponges are the simplest animals known. Unlike all other animal phyla, which have two or three-layered body plans (diploblastic or triploblastic), sponges have only a single body layer (monoblastic), and no true tissues. They have no appendages and no ability to make any movements, lacking muscle tissues. Sponges are exclusively aquatic.
