|Moon Jellyfish 2013 - Dennis Stewart|
This type of jellyfish is often cultured around the world. Their sting is not powerful because they are planktivores. The flower-like pattern in the center of the disk is composed of the reproductive organs; reproduction is both sexually and asexually. This delicate invertebrate is known to survive for only a few months in the wild, but can live for years in an aquarium environment.
