Reproduction of Marine Invetebrates, Volume IV Molluscs: Gastropods and Cephalopods describes the wide range of structural complexity and diverse modes of reproduction of gastropods and cephalopods. Each chapter discusses the asexual reproduction, sexual reproduction capacity, and developmental stages of different group of gastropods and cephalopods, including prosobranchia, opisthobranchia, pulmonata, nautiloidea, decapoda, and octopoda. Gastropods are among the most conspicuous sea animals, and species of limpets, snails, and slugs are found in all marine habitats. Cephalopods are active and important marine predators, ranging from archaic nautiloids to more recent pelagic decapods and benthic octopods, which are often considered to be one of the apexes of invertebrate evolution. They are all gonochoric and reproduce only by sexual means. All have intricate courtship behavior and derived developmental patterns. Marine biologists and researchers, scientists, and developmental biologists will find this book invaluable.

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.
