Book Description
Fossil and Recent Sponges contains articles on taxonomic, phylogenetic and ecological aspects of sponges of both biological and paleontological interest. They focus on three main topics: phylogeny and systematics, biology, and paleoecology of sponges. The reader is offered an overview over the most important aspects of current sponge research: - establishment of a new taxonomy based on mono phyletic groups (phylogenetic systematics) including recent and fossil taxa - new concepts of the biomineralisation of sponge skeletons - palaeoenvironmental analysis of fossil sponge buildups.

Book Description
Sponges are possibly the world’s oldest animals. Their ability to survive and adapt in their surroundings is truly astounding, as is the fact that they’ve been on Earth for over 700 million years. This scientific guide covers the wild world of sponges, including their life cycles, feeding behavior, and more. Fact boxes provide quick, interesting facts, while a glossary and index complete a comprehensive reading experience. Colorful images take readers on a visual journey through sponge habitats, where there’s always something new to explore.

Book Description
Excerpt from A Monograph of the British Fossil Sponges, Vol. 1: Sponges of Palæozoic and Jurassic Strata Though Fossil Sponges are mentioned in some of the earliest works in which fossils are treated of, and descriptions of them appear in nearly all subsequent works on palæontology, their true characters, until a comparatively recent date, were completely misunderstood, and their history was a mass of hopeless confusion. In the absence of any clear ideas as to the real nature of these organisms, the most heterogeneous materials were relegated to the group, and indeed it might be said to have been the practice - not altogether obsolete even now - to regard as a Sponge any fossil whose structure was too obscure to be satisfactorily placed elsewhere. One of the principal reasons for the chaos which existed was the erroneous idea, enunciated more particularly by D'Orbigny and Fromentel, that fossil Sponges belonged to an entirely extinct group, of a different nature to those now living, and consequently that no clue could be obtained to their original structures by a comparison with those of living forms. Acting on this mistaken idea, those who studied the fossil forms did not attempt to carry out a systematic investigation of their skeletal structures, like that which had been so successfully applied to existing Sponges, but they were content to limit their investigations to the external form and the superficial canal structures, features possessed in common by many Sponges whose skeletal characters are essentially diverse. The classification thus based, was for the most part valueless and misleading. Here and there observers were not wanting who noticed the importance of the skeletal structures of these fossils, and amongst these Etallon deserves special mention; but no thorough attempt was made to apply the principle of the character of the skeleton, as the basis of classification, until that successfully carried out by Professor Zittel in 1877-78.

Book Description
Atlas of Marine Invertebrate Larvae, Second Edition covers the origins and history of marine larval science, contemporary state-of-the-art approaches to larval development and biology, and the highest-quality images and schematics showing the broadest diversity of marine larvae in the animal tree of life. This book illustrates larval body plans, the anatomy of their organ systems (muscular, sensory, digestive), including distinct ciliation patterns that facilitate swimming, and the complex metamorphic changes they undergo between different larval and growth stages. Each chapter contains in-text references that direct readers to both historical and contemporary research on the forms, functions, behaviors and biogeographical distributions of marine larvae. This book is a valuable and foundational resource for biologists across various disciplines, including biodiversity, biogeography, and developmental biology. Ecologists, taxonomists, oceanographers, and environmental scientists also benefit from the complete coverage of marine larval forms offered by this book. Additionally, the broad scope and phyletic coverage of marine biodiversity presented in this atlas is ideal for students in oceanography and marine biology, animal development, biological oceanography and invertebrate zoology.

Book Description
Fossil sponges are an important and often overlooked component of the fossil record, providing valuable insights into the evolution and diversification of early life on Earth. In this comprehensive monograph, George Jennings Hinde provides a detailed overview of the fossil sponges of the British Isles, with a particular focus on the Palaeozoic and Jurassic periods. With numerous illustrations and detailed descriptions of individual species, this book is an essential resource for anyone interested in the paleontology of early life on Earth. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. This work is in the "public domain in the United States of America, and possibly other nations. Within the United States, you may freely copy and distribute this work, as no entity (individual or corporate) has a copyright on the body of the work.

Book Description
Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated). Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to all recent and many fossil taxa are provided.
