Zoology is the branch of biology that deals with animals and animal life, including the study of the structure, physiology, development, and classification of animals. An individual that specializes in the field of zoology is called a zoologist. Aristotle is regarded as the father of zoology.

  • animal physiology (deals with the physiological processes in animals)
  • animal histology (concerned with the study of animal tissues)
  • animal embryology (focused mainly on studying animal embryos)

  • zoogeography (concerned mainly with the study of animals and their habitats)
  • comparative anatomy (deals with the similarities and differences in the anatomy of different species)
  • ethology (concerned with the study of animal behavior
