The Department of Zoology was established during the Academic year of 1955 - 56 as Life Sciences. The main objective of the department is to improve the quality of education and experimental study among the students in delta and littoral districts such as Thanjavur, Nagapattinam, Thiruvarur, Ramnadu and Pudukkottai. Almost all the students are poor with minimum marks and are coming from backward areas, villages and from fisherman communities inhabiting in and around delta and coastal areas. Our department has been providing ample opportunities to the students especially from other states like Andra Pradesh and Kerala ever since its inception. B.Sc Zoology was introduced in 1962, and M.Sc. Post graduate program was introduced in 1987.During the academic year 2005 - 2006 our department has promoted as research department offering M.Phil and Ph.D research programmes in zoology.
