Corals are marine organisms in class Anthozoa of phylum Cnidaria typically living in compact colonies of many identical individual "polyps". The group includes the important reef builders that inhabit tropical oceans, which secrete calcium carbonate to form a hard skeleton.
Yellow tube sponges get their name from their hollow, chimney-like body form. They pump huge quantities of water through their bodies, filtering out the tiny particles on which they feed. At shallow depths yellow tube sponges have a shape which resembles a cactus. In deeper waters, the sponges develop long, straight tubes. Their vivid yellow colour is probably due to special fluorescent pigments in the sponge tissue.
