Deep inside caves, at the bottoms of oceans and lakes, beneath the ground: these concealed habitats are absent of light. This strange and fascinating world of complete darkness is not a solitary place-it is inhabited by millions of life forms. Yet most humans have never seen any of them. Until now. In this fascinating and sometimes eerie book, extreme wildlife photographer and scientist Dante Fenolio brings the denizens of these shadowy haunts into focus. This book shows us the many ways that life forms have adapted to lightless environments, including refinements of senses, evolution of unique body parts, and illumination using "biological flashlights". With more than 200 mesmerizing colour photographs, this book unveils bizarre creatures like the firefly squid, the giant Amazonian catfish, the Chinese cavefish, and even the human bot fly, which lives in the darkness beneath its host's skin. Fenolio's rich and vibrant images shed new light on the world's fascinating creatures of darkness.
