In the dark depths of the ocean, where camouflage can be lifesaving, scientists have discovered the blackest fish ever documented.
Researchers have found 16 species of so-called ultra-black fish, which by definition absorb more than 99.5 percent of light, making them mere shadows as they swim, scientists wrote in a study published Thursday, July 16, 2020 in the journal Current Biology, according to The New York Times.
This video is all about the newest discovery of ultra black fish in depth of the ocean. So, without further delay, let us share what we know about the ultra black fish.
The 16 species of ultra black fish includes the #fangtooth, the #Pacificblackdragon, the #anglerfish and the #blackswallower, in the waters of Monterey Bay and the Gulf of Mexico. The fish spanned seven different orders, which are large groupings that each have a shared evolutionary history, to determine that the modifications occurred independently from each other. Zoologist Karen Osborn of the Smithsonian’s National Museum of Natural History and a co-author of the study says that, “In the deep, open ocean, there is nowhere to hide and a lot of hungry predators, An animal’s only option is to blend in with the background.” According to Reuters.
Ultra-black fishes absorb light by using only the size and shape of pigment filled cellular parts, a much simpler method than any previously known. This could mean a new way to make ultra black coatings used in things like cameras.
And while little light penetrates below 650 feet, some of the #ultrablackfish live three miles underneath the surface, according to Reuters.
As the species evolved, they modified the pigment of their skin through continuous layers of melanosomes, which store light absorbing melanin, to more easily hide from predators, the Times reported. “It’s like looking at a black hole,” Duke University biologist Alexander Davis, a co-author of the study, told the newspaper.
One bioluminescent anglerfish documented by the team absorbs an astounding 99.95 percent of light, making the fish virtually invisible. It makes them about 20 times darker than everyday black objects. These fish mark the first time ultra black has been discovered in aquatic animals, researchers said.
Prosanta Chakrabarty, a biologist at Louisiana State University who wasn’t involved in the study, told the Times, “I would not be surprised if we have not yet found the blackest fish in the sea.”
Scientists have now uncovered the secrets, behind the magical disappearing act of some of the fish lurking in some of the deepest parts of the ocean. These "ultra-black" fish are among the darkest creatures ever found, evolving to camouflage themselves to predators, even with no sunlight.
