About The Author
A Textbook of Zoology – Volume I and Volume II are comprehensive academic textbooks authored by Prof. K. R. Saxena, M.Sc. Phd., who served as a Prof. in Zoology in the Department of Zoology at the University College of Science, later as Principal of the PG College of Science, Saifabad, Osmania University, Hyderabad. These books followed the syllabus prescribed for the Two-Year Intermediate Course in Andhra Pradesh and presented the fundamental principles of animal biology in a systematic and student-friendly manner.
Textbook of Zoology – Volume I was specifically compiled and structured as a comprehensive educational guide to fulfill the complete syllabus requirements for students pursuing the Intermediate Course in biological science.
Originating from the rich academic traditions of Osmania University, the book reflects Prof. Saxena's dedicated efforts to provide clear, accessible biological literature for pre-university science students.The primary content of Volume I provides a detailed, highly systematic exploration of fundamental general zoology, animal biology, and invertebrate zoology. Structured to support formal classroom instruction and rigorous academic study, the textbook thoroughly introduces essential concepts governing the animal kingdom, emphasizing zoological classification, structural organization, animal morphology, and biological diversity.
Through comparative analysis and detailed structural descriptions, the text systematically guides readers through the functional biological systems, physical characteristics, body plans, and taxonomic relationships across diverse invertebrate organism groups, conveying complex scientific principles in a clear, accessible classroom format.Beyond serving as an essential study resource for students preparing for competitive academic examinations, the work represents a lasting, valuable contribution to zoological science education.
It faithfully captures the instructional methods, pedagogical techniques, and curriculum standards established during its publication era. The book follows the syllabus prescribed for the Preserved in digital archive format for students, teachers, educators, researchers,academic libraries, and science historians, the text functions both as an informative textbook on invertebrate life and as an important historical reference for understanding the evolution of biological science education.
A Supplement to Volume I, prepared by Prof. Saxena following Intermediate syllabus revisions. It adds specialized coverage on Euglena, Obelia, and starfish, retaining the main text's presentation sequence
Textbook of Zoology – Volume II
Originally published in 1976 as fifth Edition by Sri Saraswati Book Depot Educational Publishers in Charkaman, Hyderabad.
This volume was specifically compiled and structured to fulfill the academic curriculum and syllabus requirements for students pursuing the second year of the Intermediate Course in biological science.The primary content of this volume presents foundational zoological subject matter in a structured, educational manner covering core aspects of animal biology, animal anatomy, and animal physiology.
It focuses extensively on higher animal groups, highlighting key topics in vertebrate zoology, systematic zoology, comparative zoology, and the phylum Chordata. Through detailed examinations of animal diversity and classification, the text systematically guides readers through the structural organization, functional biological systems, physical characteristics, and evolutionary relationships of diverse animal species, delivering complex biological concepts in a clear, accessible classroom format.In addition to serving as a foundational study guide for students preparing for academic examinations in zoology, the work represents a meaningful contribution to zoological science education and the history of teaching.
It reflects the teaching methods, pedagogical techniques, and academic standards established during its period. Preserved as a digital edition for students, teachers, educators, researchers, libraries, and science historians, the text functions both as an informative textbook on vertebrate biology and as an important reference for understanding the historical development of biological science education.
