แมงกะพรุนหัวคว่ำ หรือ แมงกะพรุนกลับหัว ในระยะโตเต็มวัยเรียกว่าเมดูซ่า

              The adult stage of a jellyfish is called the medusa. The male medusae will release their reproductive cells into the water column, which will than fertilize the female’s eggs. The female will then release these eggs as planula larvae, which attach to a hard substrate such as mangrove roots or jetties, becoming what is called a polyp. The polyp stage looks similar to a small sea anemone, and when the water conditions are suitable, the polyp will go through asexual reproduction in a process called strobilation. This is the budding of the medusae stage from a polyp, and multiple medusae can come from a single polyp.
