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.
Atolla wyvillei can trap its prey through the use of its hypertrophied tentacle. It can passively catch its prey by leaving the tentacle extended and allow it to catch things that may be floating nearby. The colors of its body as well as the light it emits, prevents the bioluminescent nature of its prey from being discovered inside of it.
Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. [1] Bioluminescence occurs in diverse organisms ranging from marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, dinoflagellates and terrestrial arthropods such as fireflies.
Over 90 percent of marine organisms are bioluminescent -- algae, jellyfish, squid and shrimp to name just a few. Even though bioluminescence is so common amongst sea creatures, ...
Thus, the jellyfish may change the color of its bioluminescence with depth. However, a collapse in the population of jellyfish in Friday Harbor , where GFP was originally discovered, has hampered further study of the role of GFP in the jellyfish's natural environment.
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.
Use of Bioluminescence to Attract Prey Like many creatures living in the midnight zone, the sea anemone produces its own light. This is in the form of a bioluminescent mucus that it emits.
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).
