Bioluminescence
Bioluminescence is the production of light by living organisms, such as fireflies, glow worms and mainly animals that live in the sea. The lights are produced by chemical reactions in various parts of the animals' body.
In these reactions, oxygen is combined with a substance called luciferin, and energy is given out in the form of light. Unlike our electric lights, the lights give out almost no heat. The animals turn their lights on and off by altering the amount of oxygen reaching them.
Some fungi and bacteria produce glowing light, but it is not yet clear how.
Fireflies, a kind of beetle are found in many parts of the world. Some flash while resting on trees or on the ground, and others, while flying. The lights bring the males and females together for mating. Many deep sea fishes produce light to find their way or to attract their prey.
Deep within the ocean, where sunlight cant reach, fish such as the angler fish use Bioluminescence to find their food or to attract a mate.
Sometimes the sea appears to be lit by a strange light. The light actually comes from luminescent organisms including certain bacteria and fungi. Many squids are also luminescent.
The light comes from the chemical processes that go on in the cells of these plants and animals.
Bioluminescence is light produced by a chemical reaction within a living organism.
Bioluminescence is a type of chemiluminescence, which is simply the term for a chemical reaction where light is produced.
Some bioluminescent organisms, including fireflies and fungi, are found on land.
