Thus, the giant jellyfish may appear "invisible" or glow orange very faintly in its surroundings, depending on the depth of the water. Furthermore, their bodies being made of either spongy tissue or jelly allows for the species to withstand the enormous deep ocean pressure of 40,000 kPa (5,800 pounds per square inch).

It is suggested that many firefly larvae glow to repel predators; some millipedes glow for the same purpose. [59] Some marine organisms are believed to emit light for a similar reason.
