Most people know only the jellyfish, which has been fully developed. The jellyfish is a transparent, bell-like creature that we always find on sandy beaches. The fact is that the life cycle of jellyfish is very complex. It passes through at
least six different evolutionary stages

Eggs and sperm are the most important stages of the jellyfish life cycle

Jellyfish Like most other animals reproduce sexually, this means that adult jellyfish are either male or female, jellyfish possess genital organs called gonads which produce sperm in males and eggs in females, and when jellyfish are ready to mate, the male Jellyfish release sperm through the opening of the mouth located on the underside of their bell or body. In some species of jellyfish, eggs are placed on incubator bags or egg bags on the upper part of the female arms surrounding jellyfish. Eggs are fertilized when swimming. method To male sperm, and in other species of jellyfish harbor the female eggs inside her mouth and swam the male sperm into the female jellyfish belly, the fertilized eggs will later leave the stomach and hang on the arms of female jellyfish

After fertilizing female jellyfish eggs by male sperm, they are subject to typical embryonic development such as all animals, and hatching eggs, free larvae of free blanula, exiting the mouth of jellyfish females or of incubator bags attached to the plants. The larvae are small oval And the outer layer of them are lined with fine hairs called cilia that help the larva to rush into the water, however, the kinetic force produced by the cilia is very small compared to the movement of ocean currents that can move the larva to very long distances, and the larvae can float on the surface If water is not eaten by predators, the larvae quickly fall down and settle in the solid substrate and begin to develop into the next stage of the tumor
The tumor is from the stages of the jellyfish life cycle

When the larvae descend to the seabed, they attach themselves to a hard surface and turn into a tumor, also known as stomachache. The tumor is a cylindrical, leg like structure. At the base of the tumor is a disc that sticks to the substrate. At the head is the opening of the mouth surrounded by small probes. By dragging food to the mouth, when the tumor grows, the tumor starts to sprout a new tumor from the leg area, and the growth continues and the buds form a colony of tumors. When benign tumors reach the proper size that can take several years, they begin the next stage in the Handily life cycle the sea.

When the colony is ready for the next stage of development, the tumor stem begins to develop the horizontal grooves, a process known as strangulation, and these grooves continue to deepen until they resemble a pile of dishes, and the upper grooves mature faster and faster and turn into small jellyfish known as Alvira With arms that resemble the arms of the jellyfish to a certain extent, and the process of budding that comes out of the tumors and the form of aphira is a non-sexual reproduction, which means that the jellyfish reproduce sexually and sexually, and swim freely in the water and gradually turn into adult jellyfish which Mei Almidosa which possesses a smooth and transparent body

Very informative and enlightening. I have seen the jellyfish in the ocean off the coast of California floating in their schools of millions on the current. The Man O' Wars are a beautiful, undulating thing to watch and thanks for the information @mars9
