Invertebrate zoology is a branch of biology that deals with the study of animals without backbones, such as sponges, worms, molluscs, arthropods, echinoderms and protozoans. These animals make up about 95% of all animal species on Earth and play vital roles in various ecosystems. Invertebrate zoology helps us understand the diversity, evolution, ecology, physiology, behaviour and interactions of these animals.

One of the most renowned authors and teachers of invertebrate zoology is Prof. R.L. Kotpal, who has been teaching this subject for over four decades at various universities in India. He has written several books and research papers on various aspects of invertebrate zoology, such as classification, morphology, anatomy, embryology, histology and ecology. He has also received many awards and honors for his academic excellence and contributions to the field.

One of his most popular books is "Modern Text Book of Zoology: Invertebrates", which was first published in 1988 and has been revised and updated several times since then. This book is a comprehensive and authoritative guide to the study of invertebrate zoology, covering both classical and modern topics and concepts. It is designed for undergraduate and postgraduate students as well as teachers and researchers of zoology.

Features of the book

The book is organized into 16 chapters, each covering a major group or phylum of invertebrates. The chapters are arranged according to their evolutionary relationships, starting from the simplest forms (protozoa) to the most complex ones (echinoderms). Each chapter begins with an introduction to the general characteristics, classification and types of the group, followed by detailed descriptions of selected examples or representatives of each group. The book also includes a glossary, selected references and an index at the end.

The book covers a wide range of topics and concepts related to invertebrate zoology, such as modern classification systems, origin and evolution of metazoa, organization and levels of complexity, body plans and symmetry, embryonic development and metamorphosis, organ systems and functions, locomotion and movement, feeding and digestion, respiration and circulation, excretion and osmoregulation, nervous system and sense organs, reproduction and life cycles, ecology and adaptations, parasitism and diseases, etc.

The book uses various illustrations, tables, diagrams and examples to explain the subject matter clearly and effectively. The illustrations are drawn with accuracy and detail, showing both external and internal features of different animals. The tables summarize important information such as classification schemes, diagnostic characters, comparative features, etc. The diagrams show schematic representations of structures, processes, cycles, etc. The examples are chosen from both common and uncommon species, highlighting their diversity and uniqueness.

The book offers many benefits for students and teachers of zoology, such as:

  • It provides a comprehensive and up-to-date coverage of invertebrate zoology, incorporating the latest research and developments in the field.

  • It explains the concepts and principles in a simple and lucid language, avoiding unnecessary jargon and technicalities.
