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: -Some animals are known for their ability to regrow – or regenerate – body parts following dramatic injury. Starfish are among the most famous and dramatic examples, being able to grow an entire new body from just a single arm.

Detailed explanation-3: -starfish follows the fragmentation method.

Detailed explanation-4: -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. Some starfish can regenerate from just a fragment of one arm. A single arm which has become separated from its host is known as a comet.

Detailed explanation-5: -During autotomy a starfish sheds an arm typically with part of the central disk attached. This arm regenerates into a full starfish identical to the original.
