The Department of Zoology was started 12 years after the inception of the college in 1980 with the introduction of BSc Zoology course under able leadership of Prof. N. Chandrashekharan Nair. With his retirement, in 1995, Prof. Santha S. Kumari Devi shouldered all responsibility to ensure the smooth and efficient functioning of the Department and was succeeded by Prof. R. Rasamony (2003 to 2013) and Dr. Sreekala S (2014 to 2024). Since then, the Department is headed by Dr. Vani S. Our former teachers include Prof. G. Sethuamma, Prof. K. N. R. C. Pillai, and Prof. T G Ramachandran Pillai. At present, the department team comprises three teaching faculties- Dr. Vani S (Head of the Department), Dr. Abhijith R.S. (Assistant Professor on Contract) and Dr. Bhavya L. R. (Assistant Professor on Contract). The department offers the four-year B.Sc. (Honours) Zoology programme, along with Minor, Multidisciplinary, and Value-Added courses. It also provides an open course on Public Health and Nutrition and an elective on Nutrition, Health and Lifestyle Management. The department has consistently achieved academic excellence, with university ranks and national-level achievements including CSIR-UGC NET and JRF qualifications. Alumni are placed in reputed institutions both in India and abroad. Infrastructure includes a well-equipped lab, smart classroom, instrumentation room, and a museum with over 500 preserved specimens. The department continues to inspire scientific learning and research.
