Porifera is a Latin word (Pore - Porous and Ferra - bear ) used for a group of animals having a lot of minute pores, through which water enter, circulate and leave the body. Porifera are characterized by being marine organisms with very simple taxonomic organization, so much that they do not have respiratory, circulatory and digestive systems.Their body is formed externally by pores that allow the absorption from the flow of water, a process by which it achieves its breathing, feeding, and reproduction.
