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.
