[[Cetacea]] is an [[infraorder]] that comprises the 94 species of [[whale]]s, [[dolphin]]s, and [[porpoise]]s. It is divided into [[toothed whale]]s (Odontoceti) and [[baleen whale]]s (Mysticeti), which diverged from each other in the [[Eocene]] some 50 [[mya (unit)|million years ago]] (mya). Cetaceans are descended from land-dwelling hoofed mammals, and the now extinct [[archaeocete]]s represent the several transitional phases from terrestrial to completely aquatic.<ref>{{cite book|url={{Google books|plainurl=yes|id=sD3NBQAAQBAJ |page=111}}|editor1-first=Debra L.|editor1-last=Miller|first1=Barrie G.

The following is a list of currently existing (or, in the jargon of taxonomy) '[[extant taxon|extant]]' [[species]] of the [[biology|infraorder]] [[cetacea]] (for extinct cetacean species, see the [[list of extinct cetaceans]]). The list is organized [[taxonomy (biology)|taxonomic]]ally into [[parvorder]]s, [[superfamily (taxonomy)|superfamilies]] when applicable, [[family (biology)|families]], [[subfamilies]] when applicable, [[genus]], and then species. In tabular form, seven descriptors are given for each species: the common name; the scientific name; the IUCN Red List status; a global population estimate; a global map with its range; its weight with an image of its shape, and its size relative to a [[human]]; and a photograph.

Conservation status codes listed follow the [[IUCN Red List of Threatened Species]] (v. 2014.3; data current at 20 January 2015).<ref name="iucnredlist.org">{{cite web | url = http://www.iucnredlist.org/ | title = The IUCN Red List of Threatened Species | publisher = International Union for Conservation of Nature and Natural Resources | access-date = 20 January 2015}}</ref>

Where available, the global population estimate has been listed. When not cited or footnoted differently, these are from the [[IUCN Red List of Threatened Species]] (v. 2014.3; data current at 20 January 2015).<ref name="iucnredlist.org" />

== Mysticeti: baleen whales ==
{{Main|Baleen whale}}
The baleen whales, also called whalebone whales or great whales, form the [[parvorder]] Mysticeti. Baleen whales are characterized by having [[baleen]] plates for filter feeding and two blowholes.<ref>{{cite journal |last=Karlsen |first=K. |year=1962 |title=Development of tooth germs and adjacent structures in the whalebone whale (''Balaenoptera physalus'') |journal=Hvalrådets Skrifter: Scientific Results of Marine Biological Research |volume=45 |pages=1–56 }}</ref>

=== Family Balaenidae: right whales ===
{{See also|Balaenidae}}
The family Balaenidae, the right whales, contains two genera and four species. All right whales have no ventral grooves; a distinctive head shape with a strongly arched, narrow [[rostrum (anatomy)|rostrum]], bowed lower jaw; lower lips that enfold the sides and front of the rostrum; and long, narrow, elastic baleen plates (up to nine times longer than wide) with fine baleen fringes.<ref name=Martin>{{cite book| last = Martin | first = Dr. Anthony R. | title = Whales and Dolphins | publisher = Salamander Books | location = London | year = 1991| isbn = 978-0-8160-3922-7 }}</ref>

=== Family Balaenopteridae: rorquals ===
{{See also|Rorqual}}
Rorquals are the largest group of baleen whales, with eleven species in three genera. They include the largest animal that has ever lived, the [[blue whale]]. They take their name from a [[Norwegian language|Norwegian]] word meaning "furrow whale"; all members of the family have a series of longitudinal folds of skin running from below the mouth back to the [[navel]] (except the [[sei whale]], which has shorter grooves). They allow the mouth to expand immensely when feeding.<ref>{{cite journal|last1=Goldbogen|first1=Jeremy A.|title=The Ultimate Mouthful: Lunge Feeding in Rorqual Whales|journal=American Scientist|date=2010|volume=98|issue=2|pages=124–131|doi=10.1511/2010.83.124|url=http://www.americanscientist.org/issues/pub/the-ultimate-mouthful-lunge-feeding-in-rorqual-whales|access-date=2015-11-14|archive-date=2016-10-28|archive-url=https://web.archive.org/web/20161028092321/http://www.americanscientist.org/issues/pub/the-ultimate-mouthful-lunge-feeding-in-rorqual-whales|url-status=dead|url-access=subscription}}</ref> All rorquals have these unique folds.<ref name=Martin />

{{See also|Cetotheriidae}}
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies.<ref name=Martin /> The pygmy right whale is the only [[extant taxon|extant member]] of its family.

== Odontoceti: toothed whales ==
{{Main|Toothed whale}}
The toothed whales (parvorder Odontoceti), as the name suggests, are characterized by having teeth (rather than [[baleen]]). Toothed whales are active hunters, feeding on [[fish]], [[squid]], and in some cases other [[marine mammal]]s.<ref>{{cite book |last1=Klinowska |first1=M.|last2=Cooke |first2=J.|year=1991 |title=Dolphins, Porpoises, and Whales of the World: the IUCN Red Data Book |publisher=IUCN Publications |location=Columbia University Press, NY |url=https://portals.iucn.org/library/sites/library/files/documents/RD-1991-001.pdf|isbn=978-2-88032-936-5}}</ref>

=== Family Delphinidae: oceanic dolphins ===
{{See also|Delphinidae}}
Oceanic dolphins are the members of the family Delphinidae. As the name implies, they tend to be found in the open seas, unlike the [[river dolphin]]s, although a few species such as the [[Irrawaddy dolphin]] are coastal or riverine.

The Delphinidae are characterized by having distinct [[beak]]s (unlike the Phocoenidae), two or more fused cervical vertebrae and 20 or more pairs of teeth in their upper jaws. None is more than 4&nbsp;m long.<ref name=Martin />

=== Family Kogiidae: dwarf and pygmy sperm whales ===
{{See also|Kogiidae}}
The dwarf and pygmy sperm whales resemble sperm whales, but are far smaller. They have blunt, squarish heads with narrow, underslung jaws; the flippers are set far forward, close to the head and their dorsal fins are set far back down the body.<ref>{{cite journal|last1=Huggenberger|first1=S.|last2=Leidenberger|first2=S.|last3=Oelschläger|first3=H.

=== Family Phocoenidae: porpoises ===
{{See also|Phocoenidae}}
Porpoises are small cetaceans of the family Phocoenidae. They are distinct from dolphins, although the word "porpoise" has been used to refer to any small dolphin, especially by sailors and fishermen. The most obvious visible differences between the two groups are that porpoises have a less pronounced beak, and have spade-shaped teeth as opposed to conical.<ref>{{cite web|url=https://oceanservice.noaa.gov/facts/dolphin_porpoise.html|title=What's the difference between dolphins and porpoises?|publisher=[[National Oceanic and Atmospheric Administration]]|access-date=5 December 2019}}</ref>

Porpoises, divided into seven species, live in all oceans. They span from species that live almost exclusively coastal and in rivers ([[finless porpoise]]s) to species that are entirely oceanic ([[spectacled porpoise]]).

The La Plata dolphin is the only species of the family Pontoporiidae and genus ''Pontoporia''. These dolphins are known for their long beak in relation to their relatively small body size. They have a small geographic range and are mainly found in the waters along the east coast of South America. La Plata dolphins are exclusively marine organisms, however, they are grouped with river dolphins due to the fact that they reside in the La Plata River which is a salt-water estuary. With their white or sometimes pale brown coloration, fishermen tend to call them "the white ghost", as they also tend to stray away from any human interaction.<ref>{{cite web|title=National Marine Mammal Laboratory - La Plata Dolphins|url=https://www.afsc.noaa.gov/nmml/education/cetaceans/laplata.php#many|access-date=18 March 2019|website=Alaska Fisheries Science Center - NOAA Fisheries|publisher=NOAA Fisheries}}</ref>

A beaked whale is any of at least 22 species of whale in the family Ziphiidae. Several species have only been described in the last two decades. Six genera have been identified.

They possess a unique feeding mechanism among cetaceans known as [[suction feeding]]. They are characterized by having a lower jaw that extends at least to the tip of the upper jaw, a shallow or non-existent notch between the tail flukes, a dorsal fin set far backwards, three of four fused neck vertebrae, extensive skull asymmetry and two conspicuous throat grooves forming a 'V' pattern (which aid in sucking).<ref name="Martin" />
