We have great pleasure in placing this book "Zoology" for B.Sc. Zoology first semester students. This book has been compiled exclusively as per the new semester wise CBCS pattern syllabus of Gondawana University, Gadchiroli which will implement from June-2017.

The main intend of writing this book is to present the subject matter in a concise and easily understandable form keeping in view the basic need of the students. It's our effort to make available an authentic and syllabus oriented standard study material for the students and teachers.
