The Department of Zoology had its origin in the Department of Botany in 1969-70. With the rapid advances in the field of animal science, it was felt necessary to extend it into an independent and full-fledged Department. Thus the Department of Zoology started functioning in the middle of 1972. Late Professor Dr. Mustafizur Rahman was appointed the first Headed. Since then the Department of has developed at a fast rate to its present state with a view to meeting the growing demand for trained personnel in the fields of classical as well as applied Zoology. Many changes have taken place over the last three decades.
Many of the ex-students have found careers in academic and research organizations, while others have already secured important positions in the public and private sectors of the country. The exchange of ideas between staff and students is encouraged through seminars where research findings are presented and discussed.
