Can Fish See Ir Light? Some forms of fish such as goldfish, salmon, piranha and cichlid can see infrared light. Salmon and some other freshwater fish have an enzyme that switches their visual systems to activate infrared seeing, which helps them to navigate and hunt in murky waters. What can see IR light? Summary: Science
Can Heat Sensor See Fish? As long as the water temperature changes rapidly within a few meters, thermal imaging can detect the difference. Thermal cameras can also see fish at night. Do cold blooded animals show up on thermal imaging? Here, the warmer human hand stands out against the cooler background and the snake. This
Can Infrared Light Travel Through Water? Water scatters but does not absorb ultraviolet light. It absorbs infrared light quickly – little infrared light penetrates more than 2 meters. Light is quenched rather quickly even in clear water. Only about 25 percent of incident light reaches a depth of 10 meters in the open ocean, where
