"Living Invertebrates" is an introduction to the invertebrates for students and for anyone who seeks more familiarity with the diversity of animal life on earth. It provides a complete and balanced coverage of the groups of invertebrates written in readable language, with the minimum of technical detail. The authors have selected observations and experiments that illustrate important methods, approaches and principles. In particular they have chosen material that illuminates the functional morphology, ecology and natural history of the phyla, in such a way as to bring out the inherent interest in each group. The many photographs, a large number of which have never before been published, provide an approach to the shapes, textures and aspects of invertebrates that cannot properly be communicated through words or drawings.
