The lifecycle of a jellyfish has two phases. The first is the fixed phase when the polyp attaches itself to a stone on the seabed. The second, free phase starts when the season changes. The polyp detaches itself from its stone and turns into a mini jellyfish that will then grow into an adult. Following fertilisation between two adult jellyfish, a new larva will be deposited on the seabed and the cycle starts again!
