Branches of Zoology

    Zoology is the study of the animal kingdom, which includes the anatomy, physiology, evolution, characteristic, and classification of all living and extinct animals.

    Here are the different branches of zoology and their definitions:

    • Anthrozoology Human-Animal Interactions


      Anthrozoology is a study of the interaction between humans and other animals. This sub-discipline of zoology overlaps with anthropology, veterinary medicine, ethnology, and zoology.
    • Arachnology Spiders


      Arachnology is a branch of zoology that deals with the study of spiders and related species known as arachnids (such as scorpions, harvestmen, etc.).
    • Archaeozoology Dead Animals


      Archaeozoology is the study of dead animals (faunal remains) that includes their bones, shells and other body parts. It is also known as zooarchaeology.
    • Bionics


      Bionics is the study of mechanical systems that function like living organisms or parts of living organisms. It applies biological methods and systems found in nature to the study/design of engineering systems and modern technology.
    • Cetology (Marine Mammals)


      Cetology is a branch of zoology that deals with the study of marine mammals that include whales, dolphins, porpoise, etc.

      The branch of zoology that studies the prenatal development of gametes (also known as sex cells), fertilization, and development of embryos and fetuses.
    • Entomology (Insects)


      Entomology is the study of insects. The following is the list of Entomology sub-branches that specialize in different types of insects.
