Beautiful Bioluminescence

Bioluminescence is one of those beautiful and intriguing processes that few people are lucky enough to see in person. But what is bioluminescence? The Merrium-Webster encyclopaedia defines it as:

“Emission of light by an organism or biochemical system (e.g., the glow of bacteria on decaying meat or fish, the phosphorescence of protozoans in tropical seas, the flickering signals of fireflies). It occurs in a wide range of protists and animals, including bacteria and fungi, insects, marine invertebrates, and fish. It is not known to exist naturally in true plants or in amphibians, reptiles, birds, or mammals. It results from a chemical reaction that produces radiant energy very efficiently, giving off very little heat. The essential light-emitting components are usually the organic molecule luciferin and the enzyme luciferase, which are specific for different organisms. In higher organisms, light production is used to frighten predators and to help members of a species recognize each other. Its functional role in lower organisms such as bacteria, dinoflagellates, and fungi is uncertain. Luminous species are widely scattered taxonomically, with no clear-cut pattern, though most are marine.”

Where can we see bioluminescence in action? It mostly occurs deep down in the oceans, but luckily, we can film it in action:

We can also see it up on the surface though, as seen here on the Vaadhoo island in the Maldives. This beach is famous for its bioluminescence, caused by a type of phytoplankton.
