Whale is the common name for marine mammals of the order Cetacea. The term whale is sometimes used to refer to all cetaceans, but in more common English usage it generally excludes the members of the Delphinoidea superfamily, such as dolphins and porpoises.[1] These smaller species belong to the suborder Odontoceti (toothed whales), which also includes the sperm whale, killer whale, pilot whale, and beluga whale. The other suborder of cetaceans, Mysticeti (baleen whales), includes the blue whale, which is the largest animal known to have ever existed, the humpback whale, and many other animals that feed by straining seawater through long strips of baleen that they have in the place of teeth, and from which they get their name.
