How Ultra-Black Fish Disappear into the Deep

In the deep sea, some fish have evolved to absorb nearly all light, making them almost invisible to predators. This adaptation is achieved through a high concentration of melanin in their skin, organized in a way that prevents light from scattering. These ultra-black fish not only avoid predators but also prey on bioluminescent creatures. The study of these fish could inspire the development of synthetic ultra-black materials for use in technology, such as cameras and optical instruments, where controlling stray light is crucial.
