The genus was first described in 1816 by Jean-Baptiste Lamarck in his book Histoire Naturelle des Animaux sans Vertèbres (Natural History of Invertebrates). [4] It has been suggested that Aurelia is the best-studied group of gelatinous zooplankton, with Aurelia aurita the best-studied species in the genus; two other species, Aurelia labiata ...
Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly) is a species of the family Ulmaridae. [ 1 ] [ 2 ] All species in the genus are very similar, and it is difficult to identify Aurelia medusae without genetic sampling; [ 3 ] most of what follows applies equally to all species of the genus.
Aurelia limbata is in the genus Aurelia, which is commonly called moon jellies. Aurelia is the most common and widely distributed species of jellyfish. [1] A. aurita is the closest relative to A. limbata, because they have a similar gene orientation [2] and the same life cycle.
Aurelia labiata in the Vienna Zoo. Aurelia labiata is a species of moon jellyfish. It is a cnidarian in the family Ulmaridae. [1] It is typically larger than Aurelia aurita, [2] with individuals document up to 45 cm (18 in). [3] However, much of its size range overlaps with A. aurita (up to 40 cm (16 in)), making size an imperfect diagnostic tool.
Aurelia coerulea or Asian moon jelly is a species of moon jelly in the genus Aurelia. [1] This species is native to the seas off Japan, China, Korea, and California, as well as the Mediterranean and other temperate seas. and they can also be found in coastal areas of China, Korea, California, the Mediterranean and other temperate seas.
Incredibly well-preserved fossils of the oldest swimming jellyfish, which lived 505 million years ago, were discovered at a famed fossil site in Canada.
The term jellyfish broadly corresponds to medusae, [4] that is, a life-cycle stage in the Medusozoa. The American evolutionary biologist Paulyn Cartwright gives the following general definition: Typically, medusozoan cnidarians have a pelagic, predatory jellyfish stage in their life cycle; staurozoans are the exceptions [as they are stalked]. [14]
Aurelia marginalis was first named by Louis Agassiz in 1862, who encountered the jellyfish near Florida. [4] In 1910 Alfred G. Mayer suggested that A. marginalis was a synonym of A. aurita. [5] However, there is morphological and genetic evidence that A. marginalis is indeed a separate species. [2] [3]
