Glowing fish: so different and such an amazing
• Glowing fish: so different and such an amazing
Some creatures, such as jellyfish and corals, have a tremendous ability to absorb light and convert it into its own color glow. This phenomenon is known as biofluorestsentsiya. Now scientists have discovered that this phenomenon is much more common than previously thought.
Many species of aquatic life that seem quite ordinary, deep under water look completely different. At a depth of a large part of the light spectrum is absorbed by the water, leaving basically only the blue light. Many species of fish use this light to glow neon green, orange or red.
"By creating special conditions light, similar to what occurs in the depths of the ocean, and using a special camera with the possibility of fixing the fluorescent light, we can a glimpse of this biofluorestsentnuyu universe" - says biologist David Gruber.
To catch fish during fluorescence, invisible to the human eye, with a team of Gruber used the blue light and a yellow filter chamber, blocking blue light. Thus they were able to see the fish emitted light. The mystery of this glow scientists have uncovered, for the filming of the exhibition fluorescent coral on the island of Little Cayman. One of the photos showed glowing green eel. Then the team specifically went to the Bahamas and the Solomon Islands. The expedition has been very successful, shone many water inhabitants: sharks, rays, eels.
The team announced that they have discovered 180 species with this ability. Scientists believe that animals use to communicate glow while remaining invisible to predators as the eyes of many types are equipped with luminous yellow filters, allowing you to see biofluoristsentsiyu.

The study was based on data from five expeditions. In the last journey in the Solomon Islands three experts submerged to a depth of one thousand meters for the study of fluorescent corals.
