What Are Tunicate Adults

Tunicates are also known as sea squirts. Adult tunicates are simple organisms. They are basically a barrel-shaped sack with two openings or siphons that water passes through. They draw water into their body through one siphon, filter out food like plankton, and expel the remaining water out of the other siphon.

What are most tunicate adults?

As adults, most tunicates are sessile (they do not move around) filter feeders that lack a notochord and a post-anal tail. They also lack the body segmentation that is found in other chordates.
