WebbLab 2 – Page 16 of 24 Like other scyphozoans, the life cycle of Aurelia sp. is defined by the relative importance of the medusa stage compared to the polyp stage (Figure 14).The adult medusa possesses four semicircular gonads (reproductive organs) that are contained in its gastric pouches (Figures 12 and 13).During mating, spermatozoa (or sperm) are … WebbThe scyphistomae acquire their photosynthetic algae symbionts during their preliminary development phase, though the mechanism for this is still unclear. These microorganisms live primarily in the mesoglea and lining of the cnidarian's gastrovascular system, bolstering oxygen production, and remain with the jellyfish for the rest of their lifespans.
