Sharks are unable to distinguish colors, even though their close relatives rays and chimaeras have some color vision, according to new research by scientists in Australia. Their study shows that although the eyes of sharks function over a wide range of light levels, they only have a single long-wavelength-sensitive cone type in the retina and therefore are potentially totally color blind.
