What is underwater fluorescence ?
One type of hidden magic found in the dark, nighttime depths of our oceans is fluorescence. Fluorescence is when an object releases light after excitation by another source of light. Fluorescence is different than bioluminescence. Creatures that are bioluminescent will emit light independent of another source. Rather than producing their own light, creatures that fluoresce emit light at a lower wavelength than what is irradiated upon them. For example, if you shine a blue light or UV light on some corals, they will shine green in return. However, without the blue light, these corals will not emit any light. https://www.uwphotographyguide.com/un...
