The Moon Jellyfish (Aurelia aurita) is a common jellyfish found in almost all Global Oceans, and in areas with salinity as low as 6 parts per thousand, and is mostly found in harbors and estuaries.

It feeds on plankton with organisms like mollusks and crustaceans.

These jellies are also commonly kept in captivity, and can be easily kept in captivity with the invention of the Aquarium Kreisel Tank.


The moon jellies' sting is rated low on the scale from low to high, and is completely harmless to humans unless there is a severe allergic reaction, which is rare.

To ease the stinging you should apply vinegar to the area to stop the stinging.
