A chordate (/ ˈ k ɔːr d eɪ t /) is an animal of the phylum Chordata.During some period of their life cycle, chordates possess a notochord, a dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail: these five anatomical features define this phylum.Chordates are also bilaterally symmetric, and have a coelom, metameric segmentation, and circulatory system.
