Still, certain features are common among all bioluminescent forms: They emit a steady stream of light, and the Bioluminescent light is bluish-green. The Crystal jelly jellyfish is a fascinating animal, as it possesses a protein that has been widely used in the study of biological processes in human cells. Aequorea species can be fairly difficult to tell apart, as the morphological features on which identifications are made are mostly the numbers of tentacles, numbers of radial canals, numbers of marginal statocysts, and size. No proteins. This species is thought to be synonymous with Aequorea aequorea of Osamu Shimomura, the discoverer of green fluorescent protein (GFP). Photo: iStock.

Their polyps also tend to live in colonies, and can live up to more than 2 years. They blend perfectly well with the surrounding waters and are very difficult to spot by predators having weak to normal eye sight. 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. Aequorea jellies glow with a bioluminescent protein used in the biotechnology industry. The power station uses seawater for cooling purposes and has to filter out and dispose .
