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.
The similar appearances of moon jellyfish is what has made them so hard to identify. They tend to have a variety of different sizes, however, they typically range 5–38 cm (2.0–15.0 in) in diameter with an average of 18 cm (7.1 in) wide and 8 cm (3.1 in) in height. [12]
Scyphozoa include the moon jelly Aurelia aurita, [9] in the order Semaeostomeae, and the enormous Nemopilema nomurai, in the order Rhizostomeae, found between Japan and China and which in some years causes major fisheries disruptions. The jellyfish fished commercially for food are Scyphomedusae in the order Rhizostomeae. [10]
Anatomy of a scyphozoan jellyfish. On the underside of the bell is the manubrium, a stalk-like structure hanging down from the centre, with the mouth, which also functions as the anus, at its tip. There are often four oral arms connected to the manubrium, streaming away into the water below. [31]
A new study has found that moon jellyfish have a unique survival mechanism where the creature is able to shift its remaining limbs evenly around its body.
Cubozoa is a group commonly known as box jellyfish, that occur in tropical and warm temperate seas. They have cube-shaped, transparent medusae and are heavily-armed with venomous nematocysts. Cubozoans have planula larvae, which settle and develop into sessile polyps, which subsequently metamorphose into sexual medusae, [ 11 ] the oral end of ...
Jellyfish are medusozoans, or animals with an umbrella-shaped body and stinging tentacles, like the mythical snake-haired Medusa. Medusozoans, corals and sea anemones fall under a larger group ...
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.
