Sponges
Sponges are animals of the phylum Porifera ("pore bearer"). Their bodies consist of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, and the shapes of their bodies are adapted to maximize the efficiency of the water flow...
