A goldfish is the only aquatic animal (or fish) on earth that can see infrared and ultraviolet light. Most goldfish retina ganglion cells and wavelength photopic spectral sensitivity functions reflect both wavelength additive mechanisms and wavelength opponent mechanisms.

Scientists discovered that they could track submarines, intercept trace reflections of communication lasers that took bad bounces of atmospheric interference, and even decode the ultra-faint emanation that is shed of trans-oceanic communication cables, and so much more.
