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.
