Elusive, Ultra-Black Fish Are Cloaked to Survive in the Deep Ocean

The fangtooth fish was one of 16 species of ultra-black fishes that the researchers have since identified. To be classified as ultra-black, the bar was high. Like the fangtooth, the researchers were looking for fish skin that reflected less than .5 percent of light across the visible spectrum. They collected deep-sea fish specimens from 18 different species and used a special black-reflectance light probe to measure the angles and the amount of light that were absorbed. They found that 16 of the species qualified. By comparison, man-made black materials reflect ten percent of light, and other black fish reflect two to three percent, giving ultra-black species a six-fold advantage when it comes to hiding.
