These nearly transparent jellyfish grow up to ten inches (25.4 cm) in diameter with long, wispy tentacles. 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. Other predators of jellyfish are sharks, sea turtles, penguins, tunas, and swordfish. Although these appear delicate, they are much more resistant than those of other types of jellyfish. This may be a way to get rid of the excessive chemical energy which their body doesnt need in the form of light and heat energy. It has also been examined that the bioluminescence in jellyfishes is used predominantly as a form of communication between individuals, and can be used for defense, offense, and intraspecific communication as well.
