Fluorescence Could Indicate Health of Corals

Fluorescence Could Indicate Health of CoralsCorals are well-known for the brilliant colors they sport, but less well-known is the light, or fluorescence, that most coral species give off. Monitoring the levels of this fluorescence could be an easier way for scientists to monitor the health of coral reefs around the world, a new study finds, as these reefs are subjected to stress from climate change and other factors.
