Animals in the phylum Chordata may not all have a spine (some do, which would additionally classify them as vertebrate animals), but they do all have a notochord.The notochord is like a primitive backbone, and it is present at at least some stage of development.

Chordates are bilaterally symmetrical, which means there is a line of symmetry that divides their body into halves that are roughly mirror images of each other. Chordates are animals possessing a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail for at least some period of their life cycles. Larger by only a little however, the majority of chordates are vertebrates, though they all derive from the same ancestors.
