Moon jellyfish (Lat. Aurelia sp.). It is an inshore genus that can be found in estuares and harbors and water temperatures ranging from 6–31 °C. It can reach 40 cm in diameter. It shows a strong tolerance to low DO (dissolved oxygen) conditions, which is why their population is still relatively high during the summer. The basic body plan of Aurelia consists of several parts. The animal lacks respiratory, excretory and circulatory systems. It has four bright gonads that are under the stomach. It is either male or female. It feeds by collecting medusae, plankton, and mollusk, with its tentacles, and bringing them into its body for digestion. Aurelia is known to be eaten by a wide variety of predators, including ocean sunfish, leatherback sea turtle, scyphomedusa, even herbivores, sea birds.. They are harmless to humans.
