Aurelia (genus)
''Aurelia'' is a genus of scyphozoan jellyfish, commonly called moon jellies . There are at least 13 species in the genus ''Aurelia'' including many that are still not formally described. It has been suggested that ''Aurelia'' is the best-studied group of gelatinous zooplankton, with ''Aurelia aurita'' the best-studied species in the genus; two other species, ''Aurelia labiata'' and ''Aurelia limbata'' have also been investigated (studies summarized by Arai). Since most previous studies of ''Aurelia'' were done without the benefit of genetic identification, one cannot positively attribute the results of most research to the species named. Species of ''Aurelia'' can be found in the Atlantic Ocean, the Arctic Ocean and the Pacific Ocean, and are common to the waters off California, Japan, Korea, Australia, New Zealand, the Black Sea, Indonesia, the East Coast of the United States as well as Europe.〔 ''Aurelia'' undergoes alternation of generations, whereby the sexually-reproducing pelagic medusa stage is either male or female, and the benthic polyp stage reproduces asexually.
