Impact, Responses and Future Prediction of Climate Change on the Phenology of Jellyfish

Abstract
Climate variation can be devastating to marine life. This essay mainly focuses on how jellyfish cope with changes in ocean temperature and whether they benefit or are also affected by the population's decline. In terms of whether jellyfish benefit from climate change, this paper focuses on two case studies: the mass propagation of jellyfish in the coastal areas of China and the abundance change of jellyfish in the Bering Sea area. The results conclude that jellyfish are increasing because of climate change. However, for the case study on the decrease of the race caused by the influence of jellyfish, this paper only found that it occurred in Humboldt Current, West Greenland Shelf, and Oyashio Current. Through comparative study, this paper demonstrates that jellyfish mainly benefited from climate variation because overfishing significantly reduced their predators. Critical species of the Marine food chain were transformed into flagellates. Flagellates reduce the oxygen content in the ocean. In addition, the paper found that the mortality of individual jellyfish in the study was increased by ocean acidification due to climate change. The increase in mortality rate is because the jellyfish's reproductive and body functions are greatly affected, leading to higher mortality. This discovery proves that there are still a few jellyfish that could be negatively affected by climate change. As a result, jellyfish, with their simple but adaptable bodies, gradually replaced fish as the dominant creatures in the water. Since studies of jellyfish and their corresponding measures are still scarce, researchers will need more attention to these small and unremarkable creatures in the future. Even in the face of human overfishing, their numbers are still more significant than the correct number. To restore the marine ecosystem balance, scientists must do something to reduce the number of jellyfish in the ocean.
