Zoology, or animal biology, is the branch of biology that relates to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct. The term is derived from Ancient Greek ζῷον, zōon, i.e. "animal" and λόγος, logos, i.e. "knowledge, study"
Zoology itself can be even more specific to groups of animals. For example:
- Herpetology - is the scientific study of amphibians and reptiles
- Ornithology - is the scientific study of birds
- Entomology - is the study of insects
- Arachnology - is the study of spiders, scorpions and related organisms
- Ichthyology - is the study of fishes
A scientist who studies these groups of animals is called an [something] ist, for example a herpetologist is a scientist who studies reptiles. the end bit ist is called a suffix.
Zoology is also about studying the interactions of animals:
