Regeneration vs. asexual reproduction Regeneration Starfish regenerates arms … Some 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.

In addition to sexual reproduction carried out externally, the fertilization of the egg by sperm occurs outside the uterus. The first condition, termed fissiparity, is a form of asexual propagation and in the Asteriidae is characteristic of three genera, namely, Coscinasterias (both the Reproduction. This method of asexual reproduction is found in protozoa, sponges, hydra, earthworms and starfish. Starfish Sea star regeneration. When the sperm cells come together with the eggs, the eggs are fertilized and begin to divide. And so when conditions are right and the starfish feels some need to increase its population size, it can do it by basically just splitting itself in half and the two halves growing a new body.
