| | However some authorities doubt if their notochord and nerve cord are comparable in structure to those of other chordates. | | | These features should qualify them to be included in the phylum Chordata and they were included in this phylum until fairly recently. |

| | Chordata - Animalia phylum |
| | Members of this phylum possess pharyngeal feeding slits, a dorsal skeletal rod (back spine), and a dorsal nerve cord. | | | Chordata consists of animals with complex physical structure. | | | However, these features may only appear during the embryonic stage. |

| | GENERIC OPTICAL SYSTEM OF CHORDATA |
| | The vast majority of Chordata enjoy tetrachromatic vision. | | | It is the large chordates, primarily those living on land and including human, that are limited to trichromatic vision by the spectral absorption inherent in the cornea and lens of the eye. | | | Note the generic eye of Chordata accommodates four spectral absorbers. |

| | Chordata have bilateral symmetry, which is caused by the need for forward motion. | | | The notochord stiffens the body and acts as support during movement. | | | Chordata have three germ layers and a well developed coelem, which is a body cavity bounded entirely be mesoderm. |

| | Chordate - Wikipedia, the free encyclopedia |
| | Chordates (phylum Chordata) include the vertebrates, together with several closely related invertebrates. | | | They are united by having, at some stage in their life, a notochord, a hollow dorsal nerve cord, pharyngeal slits, a dorsal hollow neural tube, and a muscular tail extending past the anus. | | | Some scientists argue, however, that the true qualifier should be pharyngeal pouches rather than slits. |

| | Amphioxus (actually Branchiostoma sp.), is an organism that is familiar to most biology students, as it is often used in the laboratory to illustrate some of the basic chordate features. | | | Sometimes considered a subphylum of the Chordata, the Cephalochordates are composed of about 22 species of small fish-like organisms commonly called lancelets. | | | Present day lancelets, such as Branchiostoma sp., bury in sand where they draw in water through their mouth and filter out small organisms for food. |
