Aequorea victoria, also sometimes called the crystal jelly, is a bioluminescent hydrozoan jellyfish, or hydromedusa, that is found off the west coast of North America.. The species is best known as the source of aequorin (a photoprotein), and green fluorescent protein (GFP); two proteins involved in bioluminescence.
Luminescent bacteria emit light as the result of a chemical reaction during which chemical energy is converted to light energy. Luminescent bacteria exist as symbiotic organisms carried within a larger organism, such as many deep sea organisms, including the Lantern Fish, the Angler fish, certain jellyfish, certain clams and the Gulper eel.
[1] [2] They are distinguished from other jellyfish by the presence of a deep groove running around the umbrella, giving them the crown shape from which they take their name. Many of the species in the order inhabit deep sea environments. [3] Crown jellyfish are able to make light through bioluminescence. When they are touched, their bells will ...
Bioluminescence is the production of visible light by a living organism (Herring 2004). Bioluminescence is a common phenomenon in marine animals found in the deep sea. Atolla wyvillei has adapted a safety response to avoid predation. When Atolla wyvillei is attacked it produces an array of blue light flashes. The propagation rate of these ...
The new species of jellyfish is considered “relatively large,” its body reaching just over 1 inch in height and its tentacles measuring over 2 inches in length, the study said.
Bioluminescence in fish began at least by the Cretaceous period. About 1,500 fish species are known to be bioluminescent; the capability evolved independently at least 27 times. Of these, 17 involved the taking up of bioluminous bacteria from the surrounding water while in the others, the intrinsic light evolved through chemical synthesis.
The same species washed up on the state park’s shore two years ago, officials said. Rare deep sea creature with ‘bioluminescent tips’ turns up on California shore. See it
