Whales, Dolphins, and Porpoises: Presentation of the Cetaceans

摘要

Whales, dolphins, and porpoises live their entire lives in the water, and in the process of adapting to this environment, became the most specialised mammals. From the small vaquita (Phocoena sinus) to the giant blue whale (Balaenoptera musculus), cetaceans have adapted to the aquatic environment in very different ways yet have retained many common anatomical and behavioural characteristics. This overview of the taxonomy, biology, and behaviour of cetaceans may help the reader to become familiar with aspects of the animals that are relevant to the design of their habitat.
