Chordata-Vertebrates, Tunicates, Lancelets. At some point, all of the organisms in this phylum have a structure called a notochord. A notochord is a flexible rod-like cord of cells that provides the main support for the organism's body during its embryonic stage.n some primitive species, the slits are used to filter food out of the water. In other species, like fish, the pharyngeal slits have gills. In other species, like mammals, the pharyngeal slits are only present during the embryonic stage. Chordates also have a dorsal nerve cord that runs down the length of the organism.
