Zoology is the study of 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 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 is the concept of applying 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.
