Bioluminescence - ever wonder how it works??

Bioluminescent life forms generate their own light in their body to carry around with them. Bioluminescent light is much like that of a glow stick in which chemicals mix together to produce a glow that is much more efficient than humans invention of incandescent light. Bioluminescent light does not produce heat and is therefore sometimes known as Cold Light!





Some species of single-celled plankton called dinoflagellates glow when disturbed. Tides, storms, swimming marine life and passing ships can cause large numbers of these plankton to produce light simultaneously. Dinoflagellates are responsible for the phenomenon known as the milky sea, which causes the ocean to glow. In some cases, this glow is so bright that it interferes with marine navigation.


Bioluminescent life forms live throughout the ocean's depths, but most exist in one particular zone -- the twilight zone. This zone is also known as the disphotic, or poorly lit, zone.







In general, the twilight zone extends from about 660 feet (201 meters) to about 3,300 feet (1006 meters) deep.
