Question: do tunicates have a cranium?
Answer: The Kingdom Animalia phylum Chordata includes three classes: lancelets, tunicates, and vertebrates. Lancelets and tunicates have no backbone or well-developed head, but all chordates have at some a notochord, a hollow nerve cord, pharyngeal pouches, and a tail. ... They also have a well-developed head protected by a skull.
