The mantis shrimp Haptosquilla trispinosa. When researchers trained H. trispinosa to associate a spectral light with a food reward, it could discriminate wavelength differences of about 25 nanometers, or about the difference between what we see as pure yellow and orange. For comparison, humans can distinguish wavelength differences of 1 to 4 nm.
