Chapter 23: Question 8

Explain why it is necessary to know the life history of a tunicate to understand why tunicates are chordates.

It is necessary to know the life history of tunicates to understand why tunicates are chordates because we can learn about the origin of vertebrates and better our knowledge of the world around us.

As adults, tunicates are highly specialized chordates, for in most species only the larval form, which resembles a microscopic tadpole, bears all the chordate hallmarks.
