Female glowworm, Lampyris noctiluca

Male and female of the species Lampyris noctiluca mating. The female of this species is a larviform and has no wings, unlike the male.

Osamu Shimomura isolated the photoprotein aequorin and its cofactor coelenterazine from the crystal jelly Aequorea victoria in 1961.

$Due to refraction, the straw dipped in water appears bent and the ruler scale compressed when viewed from a shallow angle.$

Protein structure of the luciferase of the firefly Photinus pyralis. The enzyme is a much larger molecule than luciferin.

Coelenterazine is a luciferin found in many different marine phyla from comb jellies to vertebrates. Like all luciferins, it is oxidised to produce light.

Principle of counterillumination camouflage in firefly squid, Watasenia scintillans. When seen from below by a predator, the bioluminescence helps to match the squid's brightness and color to the sea surface above.

$Thomas Young's sketch of a double-slit experiment showing diffraction. Young's experiments supported the theory that light consists of waves.$

Stauroteuthis syrtensis bioluminescent photophores

Acanthephyra purpurea has photophores along its body which it uses in defense against predators.

Pyrosoma, a colonial tunicate; each individual zooid in the colony flashes a blue-green light.

Bioluminescence is the production and emission of light by living organisms.

In living things, this process is called bioluminescence.
