Moon Jellyfish have some of the longest life spans of any of our pet jellyfish, and can typically live for up to and, if treated well, over a year. No brain, no locomotory organs, no respiratory or circulatory or digestive system, and no senses, yet they have been an evolutionary success story for millions of years as they floated about the oceans of the earth. The most common jellyfish to keep as a pet is the moon jellyfish, which lives for about 15 months. Without the influence of wind and water currents, Aurelia live alone, however, they are thought to be brought together into aggregations as a result of wind and water currents (10). They can be found alone or in large groups along almost every major coastline in the world. It is in the family Ulmaridae and the Genus Aurelia. These invertebrates are bioluminescent (glow in the dark) and a favorite item in the aquarium pet trade. A. labiata have just the opposite, where the oral arms are longer than their bell tentacles (2). They tend to have a variety of different sizes (9), however, they typically range from 5-38 centimetres in diameter with an average of 18 cm wide and 8 cm in height (10).

Identifying Features: The Moon Jellyfish (Aurelia labiata) ranges from 25 to 40 cm (9.8 to 15.8 in) in diameter and can be easily recognized by the four horseshoe-shaped rings on its bell. The most common method used to identify the species consists of selecting a jellyfish from a harbour using a device, usually a drinking glass and then photographing the subject. Moon jellyfish is typically found close to shore, including harbours and estuaries. Confused by a class within a class or It is really impossible though to tell them apart without taking samples of their DNA. There are at least 13 species in the genus Aurelia including many that are still not formally described. Animals that don't have backbones are called invertebrates.

Hydrozoans may be solitary or colonial and are extremely diverse, […] Disclaimer: Twitter. Jean-Baptiste, and Lamarck. Aurelia is a genus of scyphozoan jellyfish, commonly called moon jellies. They commonly either prey on or compete with the commercial fisheries and their larvae as well as cause several issues for trawling boats (6) such as loss of revenue due to lost fishing time and bycatch, damage done to gears in the boats and the equipment, and having to relocate due to large aggregations (13). The reproduction of Aurelia has been studied extensively by scientists. The spherical shape of the bell bares a striking similarity to the spherical shape of the moon, which is how this jellyfish received its name. The Moon Jellyfish, its scientific name being Aurelia aurita, is commonly found in groups or what are known as 'smacks' in coastal areas all over the world. Jellyfish, any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about 200 described species, or of the class Cubozoa (approximately 20 species).

Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly) is a widely studied species of the genus Aurelia. (12) The species A. aurita tends to live in all oceanic areas other than the northern arctic where-as its counterpart, A. labiata inhabits the northern polar regions of the ocean (12). Its preferred temperature is 9 °C to 19 °C, but it can be found in freezing cold waters as well and in tropical regions where the temperature exceeds 30°C. However, Aurelia typically reproduce when there are too many nutrients in the surrounding waters (2). Order: Semaeostomeae.

Currents may sweep many of these jellyfish into sheltered bays and they are often washed up on beaches. Meanwhile, life cycle reversal, in which polyps are formed directly from juvenile and sexually mature medusae or their fragments, was also observed in Aurelia sp.1. They store their prey in special pouches until they are ready to eat it and use their four oral arms (1) to bring it to the mouth (2).
