The flexible, supporting structure found only in chordates is called the notochord. The notochord is located between the nerve cord and the digestive track.
The firm flexible rod found in the dorsal area of chordates is called the notochord. It provides support and structure to the body, and is present during early development in all chordates. In most vertebrates, including humans, the notochord is eventually replaced by the vertebral column.
The majority of chordates are found in the subphylum Vertebrata, which includes organisms with a backbone composed of vertebrae. Vertebrates such as fish, amphibians, reptiles, birds, and mammals belong to this subphylum.
First off, a Chordate is anything with a Notochord, aka, a spinal column. So, of course, all vertebrae are Chordates. But also nearly any animal that has an endoskeleton, be it bony or cartilaginous. So sharks are also chordates as are most fish.
The rigid helix structure is found in spirochetes, which are spiral-shaped bacteria characterized by their flexible, corkscrew-like shape that allows them to move in a corkscrew motion. Spirilla, on the other hand, are spiral-shaped bacteria with a more rigid structure that do not exhibit the same flexible helical shape as spirochetes.
Notochord is a supporting structure found in lower chordates and in embryos of all higher chordates. It functions as a major axial supporting structure just as vertebral column does in our body.
The firm flexible rod found in the dorsal area of chordates is called the notochord. It provides support and structure to the body, and is present during early development in all chordates. In most vertebrates, including humans, the notochord is eventually replaced by the vertebral column.
A notochord. 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.
Penguins belong to the phylum Chordata because they have a notochord (flexible rod found in the back of the early embryos of all chordates) at some point in their life cycle.

Chordata is the phylum that possesses members with a notochord, which is a flexible rod-like structure that provides support. This phylum includes animals such as mammals, birds, reptiles, amphibians, and fish.

Notochord
The postanal tail in chordates serves various functions, including aiding in swimming and balance, providing propulsion, and assisting in movement and maneuvering in the water. It is one of the defining features of chordates, along with the notochord, dorsal nerve cord, and pharyngeal slits.
