The toothed whales (Suborder Odontoceti) are a diverse group, making up more than 90% of all cetaceans. Toothed whales include porpoises, dolphins, river dolphins, sperm whales, beaked whales, and white whales.
Filter feeding whales (also known as baleen whales, Suborder Mysticeti) include the northern right whale, gray whale, bowhead, fin whale, blue whale, humpback whale, minke whale, and others.
The term cetacean is used in a general sense to refer to a dolphin, a whale, or a porpoise.
