Legend has it that brain coral, known for its intricate, maze-like patterns, possesses a mysterious bioluminescence that can hypnotize predators and guide lost fish to safety. 

However, scientific research reveals that brain coral does not produce any glowing light; its patterns merely create optical illusions under certain lighting conditions. 

This enchanting myth likely arose from the interplay of natural pigments and shimmering water reflections, inspiring tales of magical underwater guidance. 

In reality, brain coral is an essential part of the reef, providing habitat and shelter for numerous marine species without any supernatural glow.
