A. capensis generally splits across the disc along the fission plane during the spring, and then each half regenerates the missing arms during the rest of the year. The fission process can last eight hours. WebSome species of starfish carry out asexual reproduction when they reach the adult stage, by means of the fission of their central disk or as a consequence of losing one of their arms.
