  1. An animal of the large phylum Chordata, comprising the vertebrates together with the sea squirts and lancelets

  1. any animal of the phylum Chordata having a notochord or spinal column
  2. of or relating to or characteristic of the Chordata
  3. Chordates (phylum Chordata) are animals which are either vertebrates or one of several closely related invertebrates. They are united by having, for at least some period of their life cycle, a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail. ...
  4. (Chordates) Animals with spinal cords. This includes all vertebrates (animals with backbones) and a few other animals with spinal cords.
  5. (Chordates) a biological division including chiefly the vertebrates, but embracing also those animals that have a notochord -- an elastic rod dividing the dorsal from the ventral regions.
  6. (chordates) members of a diverse phylum of animals that, as embryos,  possess a (1) notochord; (2) a dorsal, hollow nerve cord, (3) pharyngeal gill slits; and (4) a post-anal tail.  Adult forms usually do not possess all these features.
  7. (Chordata) Animal phylum. Contains  vertebrates (subphylum Vertebrata) and also invertebrate subphyla Urochordata and Cephalochordata.
  8. (chordata) The phylum that includes the deuterostome groups such as vertebrates who all share a structure called the notochord - a long linear structure running the length of the body - at some point in their embryological or adult anatomy.
  9. (Chordata (Phylum)) it is the Type that groups the more evolued organisms. In particular, the subphylum of the Vertebrates, in agreement with the classic theories, is divided in five classes of organisms endowed of a vertebrale column: Fish, Amphibians, Reptiles, Birds and Mammals.
  10. (Chordata) A vertebrate phylum consisting of organisms that possess a notochord at some period during their life.
  11. (Chordata) Organ system, bilateral symmetry, coelom, closed circ. one or no heart, anterior, well developed brain; notochord pharyngeal gill slits, post-anal tail, dorsal nerve cord.
  12. (Chordata) The phylum of animals to which mammals, reptiles, birds, fishes, and tunicates belong.*
  13. (Chordata) e.g. humans (Homo sapiens). Triploblastic, coelomate organisms with bilateral symmetry. Gas exchange takes place over an internal exchange surface with a large surface area (e.g. alveoli in lungs) to provide for the typically large volume. ...
  14. (Chordata) in the classification of organisms, the green iguana’s official “phylum” is termed Chordata.
  15. organism having a notochord at some stage of development - a rigid cartilaginous rod in the back extending from anterior to posterior; this group includes the vertebrates.
  16. an animal with an internal 'rod' of flexible tissue which supports its body. This rod can be bone or cartilage. Chordates with bony notochords are called vertebrates - for example mammals (including humans), fish, birds and reptiles. Invertebrate chordates include worms.
  17. An animal with a nerve cord running down its back.
  18. Clade of animal distinguished by a notochord, dorsal nerve cord, and pharyngeal gill slits. Placed with this clade is the clade Vertebrata.
