Asian Moon Jelly

Aurelia coerulea

The Asian moon jelly is one of the most widely distributed species of sea jellies found in our World Ocean. This species can quickly populate areas and reduce the amount of zooplankton by consuming it. They are believed to be originally from the northwest region of the Pacific Ocean and that humans unintentionally introduced them to Europe via maritime or shellfish transport. This species can be white to brownish pink. Its bell can reach over ten inches in diameter. This jelly reaches around two inches in length. They produce an antioxidant compound that scientists are studying for its beneficial properties.
