In the caves of Waipu and Waitomo, New Zealand, the larvae of the Arachnocampa luminosa beetle cover the ceiling with blue lights produced by bioluminescence. While the magic of such a scene might lead one to believe that this is an exceptional phenomenon, this is not the case. It exists in a multitude of living beings, from bacteria to sharks, earthworms and even certain fungi! To date, it is estimated that bioluminescence has been reinvented no less than a hundred times throughout the history of life.
In the depths of the sea, underground or at night, it allows its inhabitants to deceive or lure their prey and reveal the invisible, such as the presence of a predator or a fellow creature. At the same time, bioluminescence has found major applications in biotechnology and medicine, particularly as a labeling tool in biological research.
However, bioluminescence is often confused with another luminous phenomenon: fluorescence. Equally spectacular, fluorescence is distinguished by its own mechanisms, modes of expression, and evolutionary history.This book reveals the richness, ecological roles, and multiple scientific applications of these two phenomena. It is an invitation to discover the fascinating and still largely unknown world of living light!
