Probably one of the more recognizable and common jellyfish seen in today's zoos and aquariums. The Moon Jellyfish is of simple construction and not exactly the most interesting of the jellies. It's ability to move is limited, and so it often just drifts with the currents. Because of that, however, they are wonderful to display since they can be pushed in a sort of dance inside their watery homes. 2010-2012.
