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.
Bioluminescence is used by a variety of animals to mimic other species. Many species of deep sea fish such as the anglerfish and dragonfish make use of aggressive mimicry to attract prey. They have an appendage on their heads called an esca that contains bioluminescent bacteria able to produce a long-lasting glow which the fish can control. The ...
It is less than an inch (2.5 cm) in diameter, colorless and does not sting. [120] Some jellyfish populations have become restricted to coastal saltwater lakes, such as Jellyfish Lake in Palau. [121] Jellyfish Lake is a marine lake where millions of golden jellyfish (Mastigias spp.) migrate horizontally across the lake daily. [82]
[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 ...
a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
This species of jellyfish is known to live in the Pelagic zone of the ocean in the Indo-West Pacific, Eastern Atlantic and the Red Sea. They live and thrive in cold water and can be found as deep as over 3,000 feet below the surface. The species is bioluminescent. During the day it tends to remain in deeper waters, migrating to surface waters ...
Scientists and bioluminescence enthusiasts have enjoyed a long streak of electrifying waves across Southern California. A specific type of algae bloom creates a bioluminescent effect, but catching ...
Hydromedusan jellyfish differ from scyphozoan jellyfish because they have a muscular, shelf-like structure called a velum on the ventral surface, attached to the bell margin. Originally from the Yangtze basin in China, C. sowerbii is an introduced species now found throughout the world in bodies of fresh water. [2]
