The rational which determine the fact that neural tube of tunicates and vertebrates are similar. Also determine whether these two groups are homologous or analogous. Introduction: Tunicate is an invertebrate marine animal, belongs to subphylum Tunicata and phylum Chordata. The vertebrates are also part of phylum Chordata, chordates are characterized by the presence of dorsal nerve cord and notochords. Tunicates bear a simple body structure compare to a very different adult form of vertebrates. The close relationship between these two forms is due to the presence of notocord or a stiffening rod in the larval stage of tunicate resembles a tadpole.
