The toothed whales (systematic name Odontoceti) form an infraorder of the artiodactyl suborder Cetacea, including sperm whales, beaked whales, dolphins, and others. At least one author believes that Cetacea should be best recognized as an infraorder in the suborder Whippomorpha in Artiodactyla. As the name suggests, the suborder is characterized by the presence of teeth rather than the baleen of other whales.
