Scientists have found a fish whose skin absorbs 99.5% of light (4 photos)

Scientists are continuously working on methods of creatingperfect camouflage using numerous "tips" left by nature. In recent studies of deep-sea fish, 16 species have been shown to be extremely capable of absorbing any spectrum of light. It is noteworthy that the natural camouflage created in the process of evolution is much simpler and more effective than all the super-complex systems proposed by modern scientists.

Research team from the Smithsonian Institution andDuke University has found that fish, whose habitat is located at depths below 300 meters, where sunlight does not penetrate, developed a unique ability to camouflage. The ultra-dense arrangement of melanin molecules in the pigment layer allows some fish to absorb almost all the light that hits their skin, so that only 0.05% of this light is reflected back.

Almost perfectly black surface of fish skinessential for survival in pitch darkness, when some deep-sea creatures emit their own light, called bioluminescence. Bioluminescent lights are used to attract mates, distract predators, and lure prey.

The adaptation of some fish species causesadmiration of scientists. So the Pacific black dragon received a perfectly black body, transparent teeth and antennae, on which there is a bright bait for victims who do not suspect that a formidable predator is nearby.

Scientists have found that to create an ultra-blackcoating the fish organism uses a high concentration of melanin, which ensures almost complete absorption of light by pigment cells. The size, shape and arrangement of melanin cells allows unabsorbed light to be redirected to neighboring melanin cells, which then absorb the remaining light. Using this technology in artificial materials will help create an almost perfect black camouflage.
