In this type of medium, internal fertilization (the union of the ovum and sperm) is not common. Therefore, cnidarians experience external fertilization. Males and Females release sperm and eggs into the water, which join to make a microscopic swimming larva called a planula. Learn more about the lifecycle and reproduction of jellyfish. They first release sperm and eggs into the water in a sexual medusa stage. Most jellyfish species are hermaphrodites. This means that females and males release ovules and sperm outside of the body. "To do this, we first sterilized the polyps of the jellyfi The jellyfish belong to the "Cnidaria" phylum, which includes some 10,000 species, of which only 20 are freshwater, and the rest marine.

All cnidarians live in either a salt of fresh water aquatic environment. Interestingly enough, the reproduction of jellyfish is not carried out inside of a female jellyfishes body, as it does in mammals. The planula swims until it finds a hard surface to attach to, such as a rock or oyster shell. Jellyfish are ubiquitous predators in marine pelagic environments and can sometimes control their zooplankton prey populations. Adult parents do not contribute in rearing the young because the female dies soon after spawning. Most of us have crossed paths with this interesting animal, either through jellyfish stings or by noticing them in the ocean.

First, the male and female jellyfish release the sperm and egg into the water, allowing them to mingle and fertilize.The fertilized larva, called the planula, swims around till it finds a hard surface to attach to. First, males release gametes (sperm) through its mouth into surrounding water, which swim to the female and enter her central cavity, finally reaching her eggs. S. gemmifera was able to ingest up to 3 micro g carbon per hour, which corresponds to a daily carbon ingestion that exceeds the individual's body weight (carbon). Conversion of ingested carbon into tissue was less than 30%. A Jellyfish stinger moves faster than a bullet shot from a gun. The numerical response of S. gemmifera reached saturation at prey levels of 100 or more copepods per liter. In some female species, she keeps her eggs in brood pouches and are fertilized them by swimming through the male's sperm.
