Chemical Zoology, Volume IV: Annelida, Echiura, and Sipuncula presents chemical information on zoological significance of Annelida, Echiura, and Sipuncula. This book is organized into 13 chapters that tackle the biological and biochemical aspects of these phyla.
The opening chapter describes the comparative anatomy, phylogeny, and classification of Annelida, Echiura, and Sipuncula. The book goes on discussing the biological aspects of these phyla, including nutrition and digestion; respiration and energy metabolism; oxygen transport; and carbohydrate and nitrogen metabolism. This volume also covers these organisms' composition of guanidine compounds and phosphagens, lipids, inorganic components, and pigments. Other chapters deal with the growth and development, luminescence, endocrines, and pharmacologic properties of Annelida, Echiura, and Sipuncula.
This book is an invaluable resource for zoologists and biochemists.
