Zoology Courses After 12th – A zoology course after 12th can be beneficial for those who are interested in nature and don’t mind taking the time to learn about it. This is a great job option but first of all, we need to know about zoology. Zoology is the scientific field concerned with the study of the animal kingdom. The field of study focuses on the existence and structure, development, classification, behavior, and distribution of all living animals. Dealing with animal species that are living, dead, and very potentially extinct is something that anyone wishing to pursue a career in zoology must accomplish.
