Aurelia aurita

Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly, northern moon jelly or saucer jelly) is a species of true jellyfish in the family Ulmaridae and the type species of its genus, Aurelia. Before the 2020s, the species was considered cosmopolitan, but the taxon has since been split into at least 28 species.
