Jellyfish may be one of the “winners” in a more acidic ocean. It’s unclear whether increasing acidity is directly related to the recent increases in jellyfish prevalence,97but it does appear that ocean acidification does not harm jellyfish reproduction or the formation of their internal structures, as it does for many other forms of marine life.98It is likely that even if acidification is not directly responsible for their recent increased prevalence, it may be creating ocean conditions that are ripe for jellyfish to flourish.
