Summary:
- Researchers have discovered that the ability of fish to produce biofluorescence, where they emit colored light, has evolved more than 100 times over the past 112 million years.
- This finding suggests that biofluorescence is a common and important adaptation in the underwater world, with many different fish species developing this ability independently.
- The study provides new insights into the evolutionary history and ecological significance of biofluorescence, which can be used for communication, camouflage, and other important functions in the marine environment.
