Detailed explanation-1: -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.

Detailed explanation-2: -Starfish exhibit an asexual mode of reproduction through binary fission and regeneration. Starfish is a bisexual organism and undergoes regeneration as a method for asexual reproduction. In binary fission, the parent organism’s cell divides exactly into two genetically identical daughter cells.

Detailed explanation-3: -Asexual reproduction amongst starfish is through fission where the starfish’s central disc is split into two pieces or autotomy where one or more of the starfish’s arms are lost.

Detailed explanation-4: -Asexual reproduction is by fragmentation, a part of an arm and part of the central disk becomes detached from the “parent” and develops into an independent individual sea star. In the past, many sea stars have been “killed” by chopping them into pieces but they have been able to regenerate and grow into more sea stars.

Detailed explanation-5: -starfish follows the fragmentation method.
