in taxon whale beluga whale MSW3:14300105 white whale beluga CEC1993:1460 The beluga or white whale, *Delphinapterus leucas*, is an Arctic and sub-Arctic cetacean. It is one of two members of the family *Monodontidae*, along with the narwhal, and the only member of the genus *Delphinapterus*. This marine mammal is commonly referred to simply as the beluga or sea canary due to its high-pitched twitter. Using the term "white whale" to refer to belugas is, in the strictest sense, erroneous, as the term "whale"is usually applied to the *Mysticeti* (baleen whales) and not to toothed cetaceans which belong to the suborder *Odontoceti*, which also includes dolphins and porpoises. ] delphinapterus leucas white whale Delphinapterus leucas requires discussion
