Detailed explanation-1: -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-2: -Starfish, or sea stars, can reproduce sexually or asexually. During sexual reproduction, the male and female release sperm and eggs into the environment, resulting in fertilized free-swimming embryos.
Detailed explanation-3: -Like in humans, the sexual reproduction of sea stars involves the joining of genes from a male and a female. But some sea stars and brittle stars are able to duplicate themselves, a process called asexual reproduction.
Detailed explanation-4: -Males release sperm into the water and females release eggs. The fertilized eggs hatch into a larval form that lives as plankton, sometimes for months, before settling on the sea floor in its adult form. Regeneration: Sea stars have a remarkable ability to regenerate, or regrow, their arms and tube feet.
