Porifera, also known as sponges, are the types of phylum that live underwater. This phylum is different from other types because the porifera has many cells that cover their exoskeleton. These cells each have different types of functions. For example, because the sponge does not have a mouth , they use their tiny pores on their body. Phylum porifera 1.
