Ultraviolet visual pigment in a vertebrate: a tetrachromatic cone system in the dace

Science. 1983 Dec 2;222(4627):1021-3. doi: 10.1126/science.6648514.

Abstract

Microspectrophotometric measurements of optically isolated photoreceptors in the Japanese dace, a cyprinid fish, revealed four spectroscopically distinguishable cone pigments and one rod pigment. A visual pigment that absorbs in the near ultraviolet was found in small single cones.
