Learn more about the characteristics and natural history of jellyfish in this article. Found all over the world sometimes in huge numbers in both freshwater and sea water. Another adaptation that moon jellies have is their translucent coloring, which makes them difficult to detect from below or above. They feed on molluscs and plankton. Found on all continents (except maybe Antarctica) and in all biogeographic provinces; or in all the major oceans (Atlantic, Indian, and Pacific. Linking human well-being and jellyfish: Ecosystem services, impacts, and societal responses. They also clog up power plant water intakes, as well as desalination plants. Although it is virtually impossible to distinguish the many different subspecies of this organism without extensively studying their DNA, they are all characterized by the appearance of four reproductive organs, or 'gonads', which are each shaped like a horseshoe, and which ca… The largest recorded specimen was a lion's mane jellyfish found on the shore of Massachusetts Bay in 1870. Its size prohibited a proper assessment of its weight. A group of jellyfish is termed as ‘smack’, and when several smacks gather together to form a larger group, it is called a ‘bloom’.

The Animal Diversity Web is an educational resource written largely by and for college students. Moon jellyfishes, Aurelia aurita (Linnaeus, 1758), aka saucer jellies, moon jellies and common sea jellies, range between 5-40 cm in diameter.
