Invertebrate Zoology P S Verma
Invertebrates are animals without backbones. They may be divided into two broad groups: protostomes, which have spiral cleavage of the egg, and deuterostomes, which have radial cleavage. The former group includes the molluscs, arthropods, annelids, and brachiopods; the latter includes the echinoderms and chordates. There are many kinds of invertebrate life forms in our environment, but we humans only know a few of them.

Introduction
Welcome to the world of zoology! We’re glad you’re here. In this book, we’ll show you all about invertebrate zoology, with detailed explanations and illustrations for easy understanding. This book is organized into five chapters that cover topics such as classification and evolution of invertebrates (protosoa, metazoa), sponges (porifera), coelenterates (cnidaria), flatworms (platyhelminthes), roundworms (nematoda), annelids (annelida), molluscs (mollusca), arthropods (arthropoda), echinoderms (echinodermata) and phylum chordata. It will prove quite useful to students studying zoology at graduate level in Indian universities. So let’s get started!

- This book covers all important invertebrates, including protozoans and helminths, with detailed illustrations for easy understanding.
- It is an excellent resource for students of zoology, medical students and practicing laboratory scientists.
The text focuses on easy explanation with adequate illustrations.
The book is loaded with several high-quality illustrations that are in color and of good size. The illustrations are clear and relevant to the text. They are also well labeled, which helps in easy identification of the subject being described.
For example, in Figure 1-1 (Insects), a picture shows an ant carrying a leaf; this illustrates the fact that ants do not chew their food but suck it out by puncturing plants with their sharp jaws. Similarly, on page 19 (Spiders), there is a sketch showing how spiders walk on water: their legs spread out like fingers on one hand, thus providing more surface area for friction as they move about underwater! These illustrations make learning fun!
This book has been designed to present the subject matter in a simple and lucid manner, covering all aspects of morphology, anatomy, physiology, development and ecology of invertebrates.

The basic features of each group are discussed briefly with emphasis on salient characteristics which help in recognizing the species.
Invertebrate Zoology P S Verma is divided into nine chapters viz – Introduction to Invertebrates; Mollusca: Gastropoda (Snails); Bivalvia (Clams); Cephalopoda (Squid & Octopus) Polychaeta: Polychaetes; Echiuridea: Sea Worms; Pycnogonida: Sea Spiders; Merostomata: Sea Scorpions; Malacostraca- Crustacea Exoskeleton Arthropoda Insecta Arachnida Myriapoda scorpions harvestmen mites sea spiders crabs shrimp copepods centipedes polychaetes earthworms leeches starfish cuttlefish snails slugs earthworms molluscans spider-like forms segmented worms poly-pods crustaceans insects arachnids invertebrates bivalves
The book is organized into five parts comprising of 27 chapters.
The book is organized into five parts comprising of 27 chapters. Part I is devoted to Arthropods, Part II to Bryozoans, Part III to Sea Anemones and Corals, Parts IV and V deal with Sponges and Echinoderms respectively. Each part has a different focus as well as different level of difficulty. The first part on Arthropods contains six chapters which begin with the more basic concepts like classification and then moves onto more complicated topics such as evolution, ecology etc., In contrast, the last two parts on sponges and echinoderms are much more advanced in nature containing 13 chapters each containing detailed information on various species belonging to these groups.
It includes topics such as classification and evolution of invertebrates (protosoa, metazoa), sponges (porifera), coelenterates (cnidaria), flatworms (platyhelminthes), roundworms (nematoda), annelids (annelida), molluscs (mollusca), arthropods (arthropoda), echinoderms (echinodermata) and phylum chordata.

It is a large branch of zoology that deals with animals without backbones. The earliest fossil records date from the Cambrian period about 540 million years ago. Most are small but some are huge like the blue whale which weighs 100 tons!!

This book, designed to present the subject matter in a simple and lucid manner, is intended for undergraduate students of zoology. It will prove quite useful to students studying zoology at graduate level in Indian universities.
The book covers all the important aspects of invertebrate zoology with special reference to morphology, physiology and ecology of different groups of animals. The text has been written in a simple and lucid manner which makes it easy to read by undergraduates. A large number of illustrations have been incorporated throughout the chapters that enliven the subject matter presented in them and make it interesting for young readers as well as teachers alike.
this book is easy to read
This book is easy to read. It is written in a simple language that can be understood by people with little or no knowledge of zoology. The book contains many examples and illustrations, which help you understand difficult concepts better.
The book also includes sample questions at the end of each chapter, which will help you check if you have understood what has been taught in that chapter. These questions are followed by answers so that you can review them after some time and find out where your strengths lie, as well as areas where there is scope for improvement
Conclusion
This textbook is easy to read and comprehend. It has clear tables, diagrams and illustrations. The chapters are well organized with appropriate references at the end of each chapter. This book offers an excellent understanding of basic concepts in invertebrate zoology.
