Cephalochordata is the group of organisms which belongs to chordate sub-phylum. These organisms are defined by the presence of a notochord. The notochord remains throughout the life. The cephalochordates are marine animals. They have segmented bodies. They possess elongated bodies with a notochord that extends the length of the body. They have cirri surrounding the mouth for obtaining food. Asymmetron (also called as Epigonichthyes) and Amphioxus (also called as Branchiostoma) are cephalochordates.
