In order to be considered part of the phylum Chordata, an animal must have a backbone. What other characteristics does this phylum share? Complete digestive system, lack of segmentation, and true body cavity No central brain, incomplete body cavity, and radial symmetry Exoskeleton, jointed feet, and simple nervous system Complete body cavity, segmentation, and bilateral symmetry

Complete body cavity, segmentation, and bilateral symmetry

Explanation:

In conjuction with possessing a backbone, chordates also have a complete body cavity, segmentation, and bilateral symmetry. They possess a complete true body cavity called the coelom. They also exhibit heteromeric segmentation wherein the links between segmented regions are inconspicuous. And they majorly possess bilateral symmetry; being divisible into symmetric halves.
