Many of the animals in the deep-sea use red pigments to hide themselves because red light is one of the first wavelengths of visible light to be absorbed by the ocean (at approximately 328 feet), rendering any animal using it invisible. In these images from the Monterey Bay Research institute, the red color is visible because high-intensity lights shining from the remotely operated vehicles (ROVs) used to capture this footage illuminate the scene.
