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.
AnthrozoologyAnthrozoology is a study of interaction between humans and other animals. This sub-discipline of zoology overlaps with anthropology, veterinary medicine, ethnology and zoology.
ArachnologyArachnology is a branch of zoology that deals with the study of spiders and related species known as arachnids (such as scorpions, harvestmen, etc).
ArchaeozoologyArchaeozoology is the study of dead animals (faunal remains) that includes their bones, shells and other body parts. It is also known as zooarchaeology.
BionicsBionics 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.
CetologyCetology is a branch of zoology that deals with the study of marine mammals that include whales, dolphins, porpoise, etc.
EmbryologyThe branch of zoology that studies the prenatal development of gametes (also known as sex cells), fertilization, and development of embryos and fetuses.

Lepidopterology (Butterflies)Lepidopterology is a branch of Entomology that covers the study of butterflies and moths.
Melittology (Bees)Melittology is the study of bees. It is also known as Apiology.
Myrmecology (Ants)Myrmecology is a sub-discipline of Entomology which focuses on the study of ants.
Orthopterology (Grasshoppers)Orthopterology is a sub-discipline of Entomology which handles the study of grasshoppers, crickets, etc.
Trichopterology (Caddis Flies)Trichopterology is a sub-branch of Entomology focusing on the study of caddis flies.
Vespology (Wasps)Vespology is a sub-discipline of Entomology which specializes in the study of wasps.
EthologyEthology is a branch of zoology that deals with animal behavior under their natural habitats and studying their behavior as an adaptive trait in evolution.
HelminthologyHelminthology is the study of parasitic worms (helminths) and deals with taxonomy of helminth and the effect on their hosts.
HerpetologyHerpetology is the study of reptiles and amphibians.
Batrachology (Amphibians)Batrachology is a branch of Herpetology concerns with the study of amphibians alone.
Ophiology (Snakes)Ophiology or Ophidiology is a sub-division of Herpetology which deals with the study of ophidians or snakes.
HistologyHistology is the study of microscopic anatomy of cells and tissues of animals and plants.
IchthyologyIchthyology is a branch of zoology that covers the study of fish (also known as fish science).
MalacologyMalacology is the study of Mollusca such as snails, slugs, octopus, clams, and all animals that live in water with shells.
Conchology (Mollusk Shells)Conchology is a sub discipline of malacology that deals with the study of mollusk shells only.
MammalogyMammalogy is the study of mammals and their characteristics. Mammalogy is also referred as Mastology, Theriology or Therology.
MorphologyMorphology is a branch of zoology dealing with the study of the form and structure of organisms and their specific structural features.
NematologyNematology is a sub-discipline of zoology that studies roundworms (nematodes).
OrnithologyOrnithology is a branch of zoology that deals with the study of birds. Check out the most colorful birds in the world.
PalaeozoologyPalaeozoology is a branch of zoology that deals with the study of fossil animals to identify multi-cellular animals from geological perspective to establish prehistoric environments and their ecosystems.
PathologyPathology is the study of bodily fluids in laboratory such as blood, urine or tissues to diagnose a disease. It further narrows down to plant pathology (for plants) and veterinary pathology (for animals).
PrimatologyPrimatology is a study of living and extinct primates (monkeys, apes, and prosimians).
ProtozoologyProtozoology is a branch of zoology that deals with the study of Protozoa (which are unicellular organisms such as amoeba, etc.).
TaxonomyTaxonomy is a study that defines groups of biological organisms on the basis of shared characteristics and giving names to those groups. Check out the levels of biological organization in detail.
ZoogeographyZoogeography is the scientific study of geographical distribution of animal species (both historic and contemporary) in the world.
ZoographyZoography is study of animals and their habitats (also known as descriptive zoology).
ZoometryZoometry is a sub-division of zoology that deals with measurements (length or size) of animal parts.
ZootomyHuman Anatomy is the study of the structure of humans and their various parts whereas Zootomy specifically refers to animal anatomy.
