Zoology is the scientific study of animals, including their behavior, physiology, anatomy, and evolution. It is a branch of biology that focuses on the structure, function, growth, distribution, and classification of animals. Zoologists often study the behavior of animals in their natural habitats, as well as in captivity. They also investigate the effects of environmental factors on animal populations. Zoology is an important field of research for understanding the relationships between humans and animals, and for developing conservation strategies to protect endangered species.
