Zoology is the scientific study of animals, including their anatomy, behavior, genetics, evolution, and physiology. Zoology covers all aspects of animal life, from single-celled organisms to the more complex structures of vertebrates. It is a broad field, encompassing a range of disciplines including ecology, genetics, conservation, and animal behavior.

Zoology can be divided into several branches, including ethology (animal behavior), ecology (interactions between organisms and their environment), physiology (how animals function), morphology (form and structure of organisms), taxonomy (classification of organisms), and evolution (changes that occur in animals over time).

Zoologists work in a variety of settings, including universities, museums, research labs, and in the field. They may specialize in a particular organism or group of organisms, or may develop more general knowledge of the natural world.
