Jellyfish have appeared more frequently in large numbers since the 1990s, with particularly frequent reports during the 2000s and 2010s, affecting marine ecosystems, fisheries, tourism, and even power plants. While most attention is usually given to the medusa stage, this article highlights the lesser-known role of the polyp, a life stage that occurs on the seafloor. The polyp is crucial because, under certain environmental conditions such as temperature, light, or food availability, it can multiply and give rise to new jellyfish. In the context of climate change, understanding how this stage functions helps predict future blooms and supports the design of better strategies to monitor and manage coastal ecosystems.
