Solution
A tunicate is a marine invertebrate animal belongs to the subphylumTunicata and phylum Chordata (includes all animals with dorsal nerve cord and notochord).
Although tunicates are classified as chordates, only the larval form possesses all four common structures.
Adult tunicates are sessile and only retain pharyngeal slits and lack a notochord, a dorsal hollow nerve cord, and a post-anal tail.
