The branch of zoology that studies whales, dolphins, porpoises, and other cetaceans, including their evolution, behavior, and ecology.
From Greek 'cetus' (whale) + '-logy' (study of). Follows the Greek-based scientific naming convention established in the 18th-19th centuries.
Cetology became fashionable in the 1800s when whaling was declining and people became fascinated by the scientific study of these mysterious creatures—Melville even has a famous chapter on cetology in Moby Dick, blending literature with science.
