Asexual reproduction only requires a single parent that will pass down all of its genes to the offspring. 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. It is this form that grows into the adult medusa jellyfish. Many reach a diameter of … reproduction Asked by x2017x to Thon, Catherine, James, Natalie, Shaylon on 16 Jun 2014. These This is the common name for the species Aurelia arita, and they are one of the more common species of jellyfish. This means there is no mixing of genes and the offspring is actually a clone of the parent (barring any sort of mutations). Reproduction in Jellyfish Jellyfish have a quite complex way to reproduce offspring, they use both asexual and sexual forms. Asexual reproduction makes the daughter cnidarian a clone of the adult. There is a sexual and asexual stage to their life cycle, meaning they switch off on which form (polyp or medusa) is formed, although medusa is the dominant form. In the adult, or medusa, stage of a jellyfish , they can reproduce sexually by releasing sperm and eggs into the water, forming a planula. Males release sperm and females release eggs into the water and when the sperm and eggs combine, they produce small larvae called planula. The polyps clone themselves and bud into the next stage, called ephyra.

Muscle ligaments and may others. Throughout their lifecycle, jellyfish take on two different body forms: medusa and polyps. All cnidarian species are able to reproduce asexually, either by dividing their bodies in half and cloning themselves, or by producing buds off their bodies that grow into mature clones of the parent. The polyps can then reproduce asexually by budding off tiny jellyfish one or two millimetres across, which feed on plankton and gradually grow into full-size adult jellyfish. Some plants and unicellular organisms reproduce asexually. jellyfish life, the planula hooks on to the bottom of a smooth rock or other structure and grows into another stage of jellyfish
