, and a post-anal tail.A tunicate tadpole larva contains several chordate features, such as the notochord, dorsal nerve cord, and tail. These features are lost, however, as the larva metamorphoses into the adult form. The tunicate larva has special organs of sense and attachment, which it uses to find and occupy a suitable habitat.Although tunicates are classified as chordates, the adults do not have a notochord, a dorsal hollow nerve cord, or a post-anal tail, although they do have pharyngeal slits and an endostyle.

Water is filtered inside the sack-shaped body. However, many tunicates have a larva that is free-swimming and exhibits all chordate characteristics: it has a notochord, a dorsal nerve cord, pharyngeal slits, and a post-anal tail.

Do adult tunicates have a nerve cord?

Do tunicates have a notochord?

In the larval stage, tunicates look like little tadpoles. They can swim and have all of the characteristics of chordates – a notochord, a dorsal nerve cord, pharyngeal slits, and a post-anal tail. As tunicates mature, a sticky substance forms and they attach themselves to a rock or other fixed surface.
