The glow of the living organisms in the sea in Hong Kong
• The glow of living organisms in the sea Hong Kong
Sometimes the sea, you can admire the magnificent natural phenomenon, which can be called boring word "bioluminescence", but you can - magical glow of the sea. And the spectacle is fascinating and diverse and mysterious.
Today we go to Hong Kong and a few pictures see unusual phenomenon - the glow of living organisms in the sea.
Meet this noctiluca scintillans which has a spherical body (diameter 23 mm) with a mobile reducible tentacle. The internal environment noctiluca scintillans filled with fat inclusions, which, when mechanical or chemical stimuli (in the experiments - also with the action of electric current) are capable of bioluminescence - emission of a living organism.
The glow of the sea over the centuries was one of the greatest mysteries of the ocean. Scientists have attempted to explain the phenomenon of luminescence and phosphorus contained in water and the electrical discharges occurring during friction of molecules of water and salt and in that the night ocean sends the absorbed solar energy during the day.
The answer to the puzzle was found in 1753, when naturalist Becker could see under the magnifying glass, tiny, the size of about 2 mm in diameter, single-celled organisms, scurrying in the sea water drops with a flagellum beats and meet the flashes of light to any mechanical or chemical irritation. Glow-celled flagellates were called noctiluca scintillans, but for a long time, few scientists believed that the activities of these miserable creatures can indeed cause a phenomenon of such a grandiose scale. Now it is no doubt the fact that the sea glow caused by biological factors, the main of which is the mass reproduction of some species of unicellular flagellates, which constitute a substantial part of the plankton of the oceans. Opening nochesvetok not a discovery of the phenomenon of bioluminescence (live luminescence) as such, but merely extended the range of known human beings who have the mysterious ability to illuminate the cold ghostly light.
The name "bioluminescence" literally means "faint glow of the living." However, humanity is still only envy the efficiency of this process, because the living luminescence efficiency fantastically great: it reaches 80-90%, while the most economical lamp "daylight" is converted into light only 10-15% of the energy, and the rest energy goes into useless heat. As it turned out, it does not exist glowing plants, but there are luminous bacteria and fungi.

Live glow, despite the 250-year history of the study, still keeps a lot of mysteries. But even if we imagine that all of them will be unraveled, luminous waves of the sea, fire dance myriad fireflies under the canopy of the forest at night, squid and fish, careening into the depths, like fiery meteors will still remain one of the most mysterious and beautiful phenomena of nature on earth. The mass development periods nochesvetok illuminates everything: the splash, paddle, hairy hands into the water, fishing line and nets, and even submarines and bottoms of ships. In Crimea, there were legends telling about how, in the dark, dead of night Greek ships set out to go to the shores of the old brand and surprise capture the freedom-loving mountaineers. This plan failed due to the fact that the sea is lit up with a bluish flame and highlighted the enemy ships. Photo taken along the seashore in Hong Kong, on the long exposure.
