The most important characteristic and is the one that gives its name to the poriferous edge is that the bodies are formed by a series of pores and channels through which the water passes and, in this way, they get food and oxygen. Their bodies do not have a definite shape, although some species show radial symmetry. ![]() These are animals that do not present any type of symmetry.
