A Biofluorescent Anemone
The function of fluorescent proteins on coral reefs remains a controversial topic so far, with no concrete scientific explanation. Many theories have been proposed to explain the role these proteins play in coral. For example, some theorists argue fluorescent proteins convert sunlight’s abundant high-energy photons (violet, blue, and green) to lower energy photons, and that this conversion encourages the photosynthesis occurring in the corals’ algae symbionts. However, this theory has been challenged by evidence that transferring photons from corals’ fluorescent proteins to the algal cells is highly inefficient, proving negligible fuel for cranking the motors of photosynthetic engines.
