The notochord, which is present in the young, is gradually replaced by cartilage.

Amphicoelous centra often are integrated with a full notochord.

It had a primitive notochord, a structure that could have developed into a vertebral column later.

- A flexible rodlike structure that forms the supporting axis of the body in the lowest chordates and lowest vertebrates and in embryos of higher vertebrates
- The notochord is a flexible, rod-shaped body found in embryos of all chordates. It is composed of cells derived from the mesoderm and defines the primitive axis of the embryo. ...
- Rigid cartilaginous rod found at the dorsal midline in all chordate embryos (it is their defining feature) derived from dorsal mesoderm (chordamesoderm). In vertebrates, it is typically a transient embryonic structure.
- Rod-like primitive backbone. Found in Ascidians.
- In embryology, a rod-shaped body of cells that is the center of development of the axis of the skeleton; also called chorda dorsalis.
- An elongated cellular cord, enclosed in a sheath, which forms the primitive axial skeleton of chordate embryos and adult cephalochordates.
- Longitudinal supporting axis of body which is eventually replaced as a support by the vertebral column in teleostean fishes.
- Greek notos = back, and chorde = cord; hence, the primitive axial skeleton around which the vertebrae develop, parts persisting in the nuclei pulposi.
- Characteristic of chordates, the notochord is a stiff rod of tissue along the back of the body. In vertebrates, the backbone is deposited around the notochord and nerve cord.
