Fission starfish
WebIn asexual starfish reproduction, starfish develop offspring identical to the parent. This can be achieved through arm autotomy or fission. In arm autotomy, starfish typically shed arms with part of the central disk attached. This arm regenerates into a full starfish identical to the original through disk-dependent bidirectional regeneration.

WebSome unicellular eukaryotic organisms undergo binary fission by mitosis. In other organisms, part of the individual separates and forms a second individual. This process occurs, for example, in many asteroid echinoderms through splitting of the central disk. Some sea anemones and some coral polyps (Figure 24.2) also reproduce through fission.
Asexual reproduction in starfish takes place by fission or through autotomy of arms. In fission, the central disc breaks into two pieces and each portion then regenerates the missing parts.
