This is a list of cetaceans. The order Cetacea includes whales, dolphins, and porpoises. It has 88 living species, divided into the suborders Odontoceti (the toothed whales, including dolphins and porpoises) and Mysticeti (the baleen whales). In addition, numerous species of extinct cetaceans exist, but they are not listed here. This list contains only the known, extant cetacean species including several recent discoveries (the baiji is also included, though it is believed to have gone extinct in 2006).
Cetaceans are aquatic mammals characterised by having fusiform (streamlined) body shapes, paddle-shaped front limbs and vestigial hind limbs. Their tails have been flattened into flukes to aid propulsion.

Famous quotes containing the words list of and/or list:
“Do your children view themselves as successes or failures? Are they being encouraged to be inquisitive or passive? Are they afraid to challenge authority and to question assumptions? Do they feel comfortable adapting to change? Are they easily discouraged if they cannot arrive at a solution to a problem? The answers to those questions will give you a better appraisal of their education than any list of courses, grades, or test scores.”
—Lawrence Kutner (20th century)
“Thirty—the promise of a decade of loneliness, a thinning list of single men to know, a thinning brief-case of enthusiasm, thinning hair.”
—F. Scott Fitzgerald (1896–1940)
