The discovery of the green fluorescent protein (GFP) from the jellyfish Aequorea victoria has revolutionized cell biological research ... The seemingly monolithic structure of GFP, an 11-stranded ...

umbrella-shaped jellyfish. The sea creature — which was first spotted in 2002 in a deep-sea volcanic structure in ocean waters south of Tokyo, Japan — has a bright red "X" on its stomach.
