"Combing through history, art, and science, Peter Williams tells stories proving that these graceful watery creatures deserve our appreciation even while they elude our understanding." - Mary P. Winsor, Professor Emeritus of the IHPST, University of Toronto"Neither fish nor jelly and rather more like slime, jellyfish puzzled Aristotle. Were they animals or plants? Even the father of taxonomy, Carl Linnaeus, was stumped. In fact, Peter Williams writes in his engaging and handsomely illustrated book, they are animals of surprising sophistication, with an ingenious portfolio of stratagems . . . his book is an ambivalent experience itself. The reader is by turns wary, repulsed and fascinated by these creatures . . . Mr Williams argues persuasively, if they are ineligible for affection, they at least deserve humanity's respect." - The Economist
