Light-induced changes in corneal iridescence in fish.
The cornea of the goby Pomatoschistus minutus is iridescent. Spectral reflectance measurements show that the colour of the iridescence responds to light shifting to longer wavelengths when illuminated and shifting to shorter wavelengths when dark adapted. After 2-3 hr dark adaptation the iridescence is no longer visible.
