This group of invertebrates is closely related to vertebrates in that members have a nerve cord during embryologic development (Ruppert et al. 2004). They are commonly known as sea squirts and can be found on pilings, dock supports, boat hulls, and the ocean floor. In a study examining regeneration in a colonial species, researchers used razor blades and needles to remove individual buds and zoids from the colony (Brown et al. 2009). The authors found that circulating stem cells are responsible for the complex multi‐tissue zoid regeneration.
