Shark and ray vision comes into focus

Vision is a crucial sense for most animals, and vertebrates have evolved a highly adaptable set of opsin genes that generate light-sensitive pigments to decode the retinal image. These opsins include a rod opsin to help see ...

Discovery of a simple mechanism for color detection

Color vision, consisting of ocular color detection, is achieved with complicated neural mechanisms in the eyes. Researchers from Osaka City University in Japan have found color detection with a simple mechanism in the fish ...

Tracing the evolution of vision in fruit flies

The function of the visual photopigment rhodopsin and its action in the retina to facilitate vision is well understood. However, there remain questions about other biological functions of this family of proteins (opsins) ...
