Chemical Zoology, Volume VIII: Deuterostomians, Cyclostomes, and Fishes is an introduction to the scientific literature of chemistry and zoology. This volume presents the state of knowledge of the two sciences to gain a valid impression of both. The research papers in this volume address the problems of different chemical and zoological approaches. The book is arranged according to phyla in order to present chemical information of zoological significance; also, for chemists to see immediately the aspects of biochemical diversity that have greatest potential interest. The chapters are divided into two major sections, Section I (Primitive Deuterostomians) and Section II (Vertebrates). The sections are introduced by a discussion of the biology and systematic of the major phylum. The chapters under these sections tackle the different aspects of the biochemistry of the phylum. This volume is primarily addressed to both chemists and zoologists.
