When jellyfish are attached to coastal reefs they have a stalked (polyp) phase and a jellyfish (medusa) phase, when they float among the plankton. The jellyfish eggs are fertilized internally and develop into free-swimming planula larvae during the medusa stage. The medusa stage is the reproductive stage. The larvae will then settle on the sea floor after a brief period of floating around the water surface. The larvae will attach themselves at one end, there they then develop into polyps and grow. During the months of spring, some of the polyps will start to bud off immature jellyfish also knows as ephyra larvae. They then grow into mature jellyfish. :)
