Summary Introduction
Introduction: Chordates are deuterostomes. They are coelomates with a bilateral symmetrical body structure. Chordates are divided into three clades, namely, urochordates, cephalochordates, and vertebrates. There are four shared derived characters that differentiate the chordates from other groups of organisms. These characters are evolved from other animal clades in connection with their locomotion and obtaining food, post-anal tail, endostyle, tubular nerve cord, and notochord.
