mind. Helen Scales is our guide on an underwater journey, as we fathom the depths and watch these animals going about the glorious business of being fish. As well as the fish, we meet devoted fishwatchers past and present, from voodoo zombie potion hunters and scientists who taught fish how to walk to nonagenarian explorers of the deep sea. Woven throughout are vignettes of Helen's own aquatic explorations, from eerie nighttime dives with glowing fish and up-close encounters with giant manta rays, to floating in the middle of a swirling shoal being watched by thousands of inquisitive eyes. As well as being a rich and entertaining read, this book will inspire readers to think again about these animals and the seas they inhabit, and to go out and appreciate the wonders of fish, whether through the glass walls of an aquarium or, better still, by gazing into the fishes' wild world and swimming through it.
