Body Symmetry of Phylum Chordata Although chordates come in many shapes and sizes, they share the four characteristics listed above and they also all have bilateral symmetry. If you divide a chordate in half, you will get two equal pieces that are mirror images of each other.
There are four key characteristics to chordates. They are the  presence of a notochord, the presence of a hollow nerve cord that  is dorsal to the notochord, pharyngeal pouc â¦ hes and an endostyle.t some point in their lives, a chordate will have a notochord, a nerve cord that runs down their back, and a slit in the throat area. The phylum name Chordata came from the n â¦ otochord, a flexible rod that supports the back. They include fishes, amphibians, and reptiles.
