The phylum Cnidaria includes animals that show radial or biradial symmetry and are diploblastic. Some of these contrasting features can be determined through observation, while others . Sponges lack organs and specialized tissue; flagellated cells move water into the central cavity through the perforations, and individual cells digest food (bacteria, other microorganisms, and organic debris), excrete waste, and absorb oxygen. Larval forms are free-swimming but all adults are sessile. All sponges have tiny pores where they intake water. Within each of the two subclasses of hexactinellids are sponges with loose skeletons—spicules held together by living tissue—and sponges with fused skeletons.
