FLUORESCENT SUNSCREEN

Coral has many threats these days:warmer waters,more pollution,acidic seas...
But one of the least known is probably to much sunlight, as it contains dangerous UV light that damages DNA that may cause serous problems.
To deal with this corals have a weapon.At night coral shines by biofluorescence that absorbs the sunlight of the day and shows the same light at night with a lower wavelength than before.Research has shown that coral that biofluoreses more is more resilient to sunligth and UV rays,just like a natural fluorescent sunscreen.
