The metazoans are a group of animals that have a bilateral symmetry and a fluid-filled body. Members of this group include crustaceans, cnidarians, annelids, and flatworms. Metazoa have a three-layered water-vascular system, a single nerve ring, and a segmented body that is organized into several somatic and reproductive organs. Metazoa are classified according to their organ system, and the main divisions are based on their reproductive methods. Metazoan animals range in size from microscopic single-celled protozoa to the enormous blue whale.
