A cetologist with Orca

Cetology is a type of science. It is the study of the cetaceans. It includes whales, dolphins, and porpoises.

Cetology is the branch of marine mammal science which studies approximately eighty species of whales, dolphins, and porpoise in the scientific order Cetacea. The term was created in the mid-19th century from the Greek cetus ("whale") and -ology ("study"). Cetologists, [1]or those who study it, seek to understand and explain cetacean evolution, distribution, morphology, behavior, community dynamics, and other topics.
