Asexual reproduction in starfish takes place by fission or through autotomy of arms. This phylum is characterized by. Organisms that reproduce sexually yield a smaller number of offspring, but the large amount of variation in their genes makes them less susceptible to disease. Starfishare classified in the phylum Echinodermata, which include organisms like sea cucumers and sea urchans. In autotomy, an arm is shed with part of the central disc attached, which continues to live independently as a "comet", eventually growing a new set of arms.
