Zoology is the division of biology that deals with the animal kingdom. It is the scientific study of everything having to do with animals, just as botany is the scientific study of plants. Zoology is a huge field that covers the classification of every animal on earth as well as many broader fields of experimentation and inquiry related to animal life. There are several sub-branches within this field, including ethology, zoography, and anthrozoology. Additionally, zoologists often specialize in the study of specific types of animals. Zoology is not concerned only with the study of the animals that are living on earth at present time but also those which lived in the past and have disappeared or have become extinct. This text will give you an overview of zoology.
