Aurelia undergoes alternation of generations, whereby the sexually-reproducing pelagic medusa stage is either male or female, and the benthic polyp stage reproduces asexually. Meanwhile, life cycle reversal, in which polyps are formed directly from juvenile and sexually mature medusae or their fragments, was also observed in Aurelia coerulea ...
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 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 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.
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 hyalina is a species of true jellyfish belonging to the family Ulmaridae. [1] It was formerly considered conspecific with Aurelia limbata. [2]
