LED to help scientists discover the fluorescence of fish communication signal"

In early January this year, the latest published in the "Public Library of science" (PLOS ONE) a research journal, the scientists used LED lamps and the lens used in the Caribbean and West Pacific tropical waters of several fish special filter was shooting. Because these filters can simulate the filter in the fish's cornea, scientists have found that the fish in the eye can be seen with the eyes or other species in the eyes of a very different. The results showed that, in the eyes of fish may be seen in other fish special fluorescent color patterns.

The study found that there are 180 species of fish with bioluminescent patterns, which is more than the number of people think. With the protection of color in reef fish with bioluminescent patterns, such as eel, fish, fish, catfish, lizard goby and flounder etc.. Scientists believe that these fish may use biological fluorescence to carry out protective camouflage or other similar information. If such bioluminescence is capable of delivering information, this will provide a "private" communication signal for the fish, because the predator may not be able to see this type of biological fluorescent pattern.
