This may attract night-flying insects and aid in spore dispersal, but other functions may also be involved. [49] Quantula striata is the only known bioluminescent terrestrial mollusk. Pulses of light are emitted from a gland near the front of the foot and may have a communicative function, although the adaptive significance is not fully ...
In the second stage, reduced luciferin is oxidized by an insoluble luciferase that releases the energy in the form of bluish-green light. Conditions that affect the growth of fungi, such as pH, light and temperature, have been found to influence bioluminescence, suggesting a link between metabolic activity and fungal bioluminescence.

Some examples of glow-in-the-dark materials do not glow by phosphorescence. For example, glow sticks glow due to a chemiluminescent process which is commonly mistaken for phosphorescence. In chemiluminescence, an excited state is created via a chemical reaction. The light emission tracks the kinetic progress of the underlying chemical reaction.
They light the entire house at night" (tr. Laufer 1912: 64). Chinese dragons are frequently depicted with a flaming pearl or gem under their chin or in their claws. According to the German anthropologist Wolfram Eberhard , the long dragon is a symbol of clouds and rainstorms, and when it plays with a ball or pearl, this signifies the swallowing ...

The light can be seen by males up to 45 metres away. The light is emitted continuously, although they will wave their abdomens from side to side, which gives the impression of it brightening and dimming. Larvae are sometimes seen to glow, although they seem able to turn off their light more easily than the female, especially when disturbed.
A "permanent" illumination watch dial Tritium-illuminated handgun night sights on an FN Five-seven. These light sources are most often seen as "permanent" illumination for the hands of wristwatches intended for diving, nighttime, or combat use. They are also used in glowing novelty keychains and in self-illuminated exit signs.
