In some species, the male places a sperm packet inside the bell of the female, and the eggs develop there instead of in the open water. Your email address will not be published. 5. The jellyfish life cycle begins as eggs and sperms from the male and female Jellyfish. It is a free swimming tinny thing which is bilaterally symmetric. Once the sperms fertilize the eggs, the development of eggs sets off. On the other hand, during the medusa phase, the reproductive stage, they begin to be free-swimming and stay afloat among plankton. As an adult, it is a free-roaming animal known as a medusa.
