Are they really our cousins? One clue that tunicates are related to vertebrates is found in the tunicate larva, or tadpole. It even looks like a tiny tadpole, and has a nerve cord down its back, similar to the nerve cord found inside the vertebrae of all vertebrates. The Cerebral Vesicle is equivalent to a vertebrate's brain.

Tunicates differ strongly in appearance between the adult and larva. • The larval form possesses more of the chordate characteristics than the adult form (see figure). Adult is sessile (and sometimes colonial), and must obtain food by siphoning sea water through its … One important question in evolutionary biology concerns the origin of vertebrates from invertebrates. The current consensus is that the proximate ancestor of vertebrates was an invertebrate chordate. Today, the invertebrate chordates comprise cephalochordates (amphioxus) and tunicates (each a subphylum in the phylum Chordata, which also includes the vertebrate subphylum).

In some chordate embryos the nerve cord develops from the central nervous system. The larval stage of tunicates also has a nerve cord. Q: Vertebrates and tunicates share 1 a notochord and a dorsal, hollow nerve cord. 2 the formation of structures from the neural crest. 3 jaws adapted for feeding. 4 an endoskeleton that includes a skull.

Notochord is a skeletal structure, which resembles a flexible rod, made up of cells, filled with fluid. In the case of vertebrates, the notochord is surrounded by a joined skeleton. In tunicates, these characters are observed in the larval stage. Most of the chordate embryo has a dorsal, hollow nerve cord. In some chordate embryos the nerve cord develops from the central nervous system.
