In this series of three books, the author escorts the reader on a fascinating and inspiring exploration of areas of the biological world unseen and unknown by most. In each volume, the author presents often complex scientific ideas in a style that is lively and easily understood. Together with stunning 3D images, taken using one of the most modern and powerful scanning electron microscopes available, the books present a unique portrait of the biosphere. Microscopic Worlds, Volume 1 showcases the complexity and beauty of microscopic organisms that inhabit the oceans - from surface waters to the sea floor. A huge variety of small planktonic species make up the 'grass' of the oceans: these not only represent the 'fuel' on which all other marine species depend, they have also had a significant impact on the evolution of the biosphere. This is the starting point for a lively discussion and systematic portrait of ocean biology at the microscopic level.
