The Medusa phase is the jellyfish form that we're familiar with. Jellyfish live an average of 3 - 6 months in the medusa phase, but could spend years in the polyp phase, with some never actually maturing into a an adult medusa.ellyfish live an average of 3 - 6 months in the medusa phase, but could spend years in the polyp phase, with some never actually maturing into a an adult medusa.
In the adult, or medusa, stage of a jellyfish, they can reproduce sexually by releasing sperm and eggs into the water, forming a planula. In this larval stage of jellyfish life, the planula hooks on to the bottom of a smooth rock or other structure and grows into another stage of jellyfish life, the polyp--which resembles a miniature sea anemone. During this stage, which can last for several months or years, asexual reproduction occurs. The polyps clone themselves and bud, or strobilate, into another stage of jellyfish life, called ephyra. It is this form that grows into the adult medusa jellyfish.
