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.
Discussions of "jellyfish DNA" that can make "glowing" animals often refer to transgenic animals that express the green fluorescent protein, not aequorin, although both originally derive from the same animal. Apoaequorin, the protein portion of aequorin, is an ingredient in the dietary supplement Prevagen.
Aequorea vitrina, commonly called the crystal jellyfish, crystal jelly, lampshade or disk jellyfish, [2] is a species of hydrozoan in the family Aequoreidae. [ 3 ] [ 4 ] The specific name vitrina means " glassy ", due to its transparent appearance; it should not be confused with Aequorea victoria , which is also sometimes called the crystal jelly.
Aequorea forskalea Scientific classification Domain: Eukaryota Kingdom: Animalia Phylum: Cnidaria Class: Hydrozoa Order: Leptothecata Family: Aequoreidae Genus: Aequorea Species: A. forskalea Binomial name Aequorea forskalea Péron & Lesueur, 1810 Synonyms List Aequorea aequorea (Forsskål, 1775) Medusa aequorea Forsskål, 1775 Aequorea stauroglypha Péron & Lesueur, 1810 Staurobrachium ...
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.

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.
Without notice, the waters off of California beaches will sometimes transform into a rusty-red color, driving surfers away. It's a massive, unpredictable bloom of single-celled, red plankton, and ...
