The digested food is moved from the cardiac stomach to the pyloric stomach where further digestion occurs. In sexual reproduction the process meiosis is used, and when asexual reproduction is used, the processes of budding fragmentation, or parthenogenesis are done. Through the years the starfish will grow bigger as a whole using the process of mitosis. The organism Choriaster granulatus is a multicellular eukaryotic organism.
