Aequorea victoria
Another, well-studied example of fluorescence in the ocean is the hydrozoan "Aequorea victoria". This jellyfish lives in the photic zone off the west coast of North America and was identified as a carrier of green fluorescent protein (GFP) by Osamu Shimomura. The gene for these green fluorescent proteins has been isolated and is scientifically significant because it is widely used in genetic studies to indicate the expression of other genes.
