The crystal jelly (Aequorea victoria) has been called "the most influential bioluminescent marine organism."

This cnidarian possesses green fluorescent protein (GFP) and a photoprotein (or a protein that gives off light) called aequorin, both of which are used in laboratory, clinical and molecular research. Proteins from this sea jelly are also being studied for use in early detection of cancer.
