The Phylum Chordata, the chordates, is the classication of organisms that possess a structure called a notochord, at least during some part of their development. The best known chordates are the vertebrates (fishes, amphibians, reptiles, birds, mammals). The vertebrates and hagfishes together comprise the taxon Craniata. Also included in the phylum are the tunicates (Urochordata), lancelets (Cephalochordata). Some extinct groups are also assigned to this phylum.
