Outline of zoology

The following outline is provided as an overview of and topical guide to zoology:

Zoology – study of animals. Zoology, or "animal biology", is the branch of biology that relates to the animal kingdom, including the identification, structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek word ζῷον (zōon), i.e. "animal" and λόγος, (logos), i.e. "knowledge, study".^[1] To study the variety of animals that exist (or have existed), see list of animals by common name and lists of animals.

By nature of studies[edit]

Anatomy - the study of the internal structure of animals
- Comparative anatomy - comparative anatomy of different animals
- Dermatology - study of skin
- Embryology - study of embryonic development
- Histology - study of tissues
- Osteology - study of bones

- Mendelian genetics - genetics based on Mendelian inheritance
- Molecular genetics - study of gene expression and behaviour
- Non-Mendelian genetics - genetics that does not follow Mendel's laws
Morphology - the study of the external structure of animals
- Anatomy - internal morphology
- Eidonomy - external morphology

Zooarchaeology - study of animal remains in relation to ancient people
Zoogeography - Zoogeography is the scientific study of geographical distribution of animal species (both historic and contemporary) in the world
Zoography - Zoography is study of animals and their habitats (also known as descriptive zoology)
