Beetles do it. As do fish. And squid, sharks, jellyfish, salps, dinoflagellates, and a host of other invertebrates. Bioluminescence, the production of light by living organisms, is one of nature’s most awe-inspiring spectacles and has fascinated humans since time immemorial. Luminous Creatures, written by bioluminescence researcher Michel Anctil, is a chunky book that charts the history of scientific research on this phenomenon by examining the lives and achievements of many of the key players involved. Along the way, it lifts the lid on many of the wondrous details of bioluminescence.
