Synopsis
Explore how a tiny snail’s early cells build a complete animal, from initial cleavage to larval form.
This nonfiction work presents a careful study of the early steps of development in Crepidula, focusing on how the egg divides, how germ layers form, and how the embryo aligns with the future body plan. It compares species, explains key concepts in embryology, and discusses the significance of cleavage and cell lineage for understanding normal and regenerative development. The text emphasizes ground-truth observation and the logical connections between early cell events and later organs.
- How the egg divides and forms distinct cell lineages that become body parts
- Formation of the germ layers and how they relate to the developing embryo
- Development of the velum, shell gland, foot, and other organs
- How orientation, axes, and shell asymmetry arise during early development
Ideal for readers of embryology, Mollusca biology, and students seeking a clear, methodical look at early development.

Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Évaluation du vendeur 4 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book delves into the captivating world of Crepidula, a genus of marine gastropods boasting unique and diverse forms. The author explores the fascinating embryology of these creatures, revealing the intricate processes that unfold as they transition from egg to adulthood. Through detailed observations and illustrations, the author provides valuable insights into the complexities of early development in this group of mollusks. Examining the formation of Crepidula's various organs and structures, the book highlights the similarities and variations in their developmental patterns. The author carefully traces the emergence of the head vesicle, velum, and foot, unveiling the mechanisms that shape these essential features. Moreover, the book explores the role of cleavage, gastrulation, and organogenesis in shaping the overall morphology of Crepidula. Throughout the book, the author emphasizes the significance of Crepidula's developmental processes within the broader context of evolutionary biology. By comparing Crepidula to other gastropod species, the author sheds light on the potential influence of environmental factors and natural selection on the evolution of developmental patterns in marine organisms. In conclusion, this book offers a comprehensive analysis of Crepidula's embryology, providing a deeper understanding of the fundamental principles and variations that govern the early development of these marine gastropods. It invites readers to delve into this intricate world, revealing the remarkable diversity of life's forms and the underlying processes that shape their development. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781332054190_0
