In fact, they use two methods, sexual and asexual, both of which will produce offspring. In addition, their fecal pellets provide nutrition for the vast array of bottom feeders. Although the mesh of their feeding net is efficient enough to catch a variety of different sizes of particles from bacteria to larva, their main food is phytoplankton. They are free-swimming marine animals that use jet propulsion both to move and to eat, pumping water through their contracting gelatinous bodies equipped with internal filters.
