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 (cnidarian) Aurelia. (cnidarian) Aurelia is a genus of jellyfish that are commonly called moon jellies, which are in the class Scyphozoa. There are currently 25 accepted species and many that are still not formally described. [1][2][3] The genus was first described in 1816 by Jean-Baptiste Lamarck in his book Histoire Naturelle des ...
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.
Jellyfish. Spotted jellies swimming in a Tokyo aquarium. Jellyfish, also known as sea jellies, are the medusa -phase of certain gelatinous members of the subphylum Medusozoa, which is a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are ...
The Scyphozoa are an exclusively marine class of the phylum Cnidaria, [2] referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word skyphos (σκύφος), denoting a kind of drinking cup and alluding to the cup shape of the organism. [3] Scyphozoans have existed from the earliest Cambrian to the ...
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.
Gobs of moon jellyfish have been spotted washing up on the beaches or floating in the waters of the Gulf of Mexico in recent days. In this case, the number of jellyfish can be attributed to a ...
Rhopalium. Moon jelly (Aurelia aurita) with rhopalia visible in indentations of rim. Rhopalia (singular: rhopalium) from Ancient Greek ῥόπαλον (rhópalon) 'club' are small sensory structures of certain Scyphozoan (true jellyfish) and Cubozoan (box jellyfish) species.
