According tomedia reports, the goths knew that black was cool. Some fish that live in the deep sea know this too. A team of researchers is uncovering the secrets of fish hidden in black. The fish are known to have evolved special skin features that could help them avoid predators who hunt with bioluminescence. Researchers including Alexander Davis, a Ph.D. student in biology at Duke University, published a study of the super-black fish Thursday in the journal Current Biology.
They found that the skin of at least 16 deep-sea fish absorbs more than 99.5 percent of light. They are the ultimate pretenders in the depths of the ocean.
Listening to the name can also feel that the deep-sea dragonfish and ordinary fangfish are by no means cute-looking creatures in the ocean. For neurotic humans, they may seem as scary as nightmares, but for scientists looking for ways to develop new ultra-black materials, they are lovely.
Vantablack is the most famous ultra-black coating designed for defense and aerospace applications, but also in architecture and the arts. However, this is not the only one. Last year, the Massachusetts Institute of Technology added a new “blackblack” material.
The marine team used spectrometers to measure the light reflected by the skin of fish caught from Monterey Bay and the Gulf of Mexico. These deep-sea inhabitants live a mile below sea level.
Duke University said in a press release Thursday that the darkest species they found was a shorter-than-golf-seat herring, which absorbs a very, very large amount of light, with little light reflected back to the eye and only 0.04 percent.
Scientists have discovered the difference between black fish and ultra-black fish by focusing on the melanosomes.
“Other normal black-skinned cold-blooded animals have tiny pearly melanin, while ultra-black animals are larger and more like well-shaped melanosis,” Duke said. “In addition, the structure of the super-black fish is closer. Computer simulations show that these melanosomes have the best geometry for swallowing light.
Imitation can help engineers develop cheaper, more flexible, and more durable ultra-black materials that can be used in optical technologies such as telescopes, cameras and camouflage, according to Karen Osborn, co-author of the study. Osborn is a zoologist at the Smithsonian’s National Museum of Natural History.
However, the ultra-black fish poses some challenges for scientists to take pictures. “No matter how you set up the camera or the lights – they absorb all the light,” says Osborn. “
Fortunately, Osborn captured the amazing teeth of an ultra-black deep-sea dragon fish and a golden-eyed python.
