What organisms are found in porifera?
Porifera are sea sponges. They have no symmetry (asymmetrical) and they are one of the most basic forms of life. They have a 2 cell layer wall made of collar cells, spicules, amoeba like cells, and a layer of epidermal like cells. The spicules and the amoeba like cells are in between the layer of collar cells and epidermal cells. Sponges also have pores throughout their structure. Porifera include freshwater sponges as well of marine varieties. Freshwater sponges are common although not obvious. Frequently they are green in color due to included algae.
