The salmon compensate for this: A simple biochemical switch in their retinas gradually enhances their ability to see infrared light. The salmon effectively transform their eyes into night-vision goggles, so they can see further into the murky water where they’ll fight, mate, spawn, and die.
How good is salmon eyesight?
