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 two proteins involved in bioluminescence, aequorin, a photoprotein, and green fluorescent protein (GFP). Their discoverers, Osamu Shimomura and colleagues, won the 2008 Nobel Prize in Chemistry for their work on GFP.
