For example, adult echinoderms are radially symmetric (unlike their larvae), while some parasitic worms have extremely simplified body structures. Many bilaterian phyla have primary larvae which swim with cilia and have an apical organ containing sensory cells. They also have a gut that extends through the basically cylindrical body from mouth to anus. Many bilaterians have a combination of circular muscles that constrict the body, making it longer, and an opposing set of longitudinal muscles, that shorten the body; these enable soft-bodied animals with a hydrostatic skeleton to move by peristalsis.
