		Living cetaceans are divided into two distinct suborders, Mysticeti and Odontoceti, which are divided further into a total of thirteen families.
		Those cetaceans classified in the suborder Odontoceti are toothed whales, dolphins, and porpoises.
		Odontoceti may have anywhere from eight to 250 teeth, and their eyesight ranges from poor to excellent.

	CLASSIFICATION: SUBORDER ODONTOCETI (Site not responding. Last check: 2007-10-20)
		Odontoceti represent cetaceans with teeth that prey on fish, seals and other cetaceans.
		There are a few Odontoceti that are toothless but do not have baleen plates to classify them as Mysticeti.
		Notice the long forehead called the melon (fatty tissue) where sound leaves the skull during echolocation.

	Cetaceans
		There are two suborders of cetaceans, the toothed whales (Odontoceti) and the baleen whales (Mysticeti).
		Odontoceti: There are six families of toothed whales, including river dolphins (Platanistidae), ocean dolphins (Delphinidae), porpoises (Phocoenidae), white whales (Monodontidae), sperm whales (Physeteridae), and beaked whales (Ziphiidae).
		Most toothed whales have a beak-like snout filled with teeth and a forehead that rises in a rounded curve called a "melon".

	Marine Mammals I: The Cetaceans
		The second group is the Odontoceti, or toothed whales, porpoises and killer whales are in this group.
		The Odontoceti, or toothed whales, first appear in the fossil record in the late Eocene Period, and probably developed from the Archaeoceti.
		The Odontoceti make up the majority of our modern whales, and include the sperm whale, beaked whale, pilot whale, killer whale, beluga, narwhal, and porpoises (which include the dolphins).

	Cetacea - Wikipedia, the free encyclopedia
		Cetaceans are nearly hairless, and are insulated by a thick layer of blubber.
		When it comes to food and feeding, this is where cetaceans can be separated into two distinct groups.
		The 'toothed whales' or Odontoceti usually have lots of teeth that they use for catching fish, squid or other marine life.

		The primary difference between Mysticeti and Odontoceti whales is their feeding mechanism.
		The Odontoceti are equipped with teeth to tear their food, and the Mysticeti have a special filtration system created by baleen.
		Baleen is a flexible horn-like material that grows in plates from the upper jaw of the Mysticeti (fig.

	Killer Whales: Scientific Classification
		This large order of approximately 80 living species is divided into three suborders: the toothed whales or Odontoceti (killer whales, dolphins, porpoises, beluga whales, narwhals, beaked whales, and sperm whales), the baleen whales or Mysticeti (blue whales, humpback whales, gray whales, and right whales), and the Archaeoceti (a group of fossil whales, now extinct).
		Ambulocetes natans was discovered in Pakistan and fossil remains show a legged land animal that also feature several characteristics of whales.
		The scientific order Cetacea is further divided into three suborders: the Odontoceti, the Mysticeti, and the Archaeoceti.

		This group includes all the whales and is subdivided into two important groups: the toothed whales or the Odontoceti (odonto = toothed; ceti = whales) (killer whales, dolphins and porpoises) and the baleen whales or the Mysticeti (mysti = moustache; ceti = whales) (blue whales, grey whales, right whales and others).
		The toothed whales or Odontoceti have strong conical or pointed teeth in their jaws.
		Dolphins and porpoises belong to the Odontoceti as they both have teeth in their jaws.

		The Odontoceti have teeth and a single blowhole, and the Mysticeti are toothless but have baleen, or whalebone, forming a set of horny plates that acts as a sieve, and two blowholes.
		The Odontoceti feed on fish and squid while the Mysticeti filter plankton and small fish with their baleen.
		The migratory whales move north in spring and south as winter approaches.

		Dolphins are mammals, which means that they bare their young live, that they nurse their young, and that they breath air.
		This massive mammal is the largest animal ever thought to have lived on the planet and measures 100 feet and 150 tons.
		Porpoise are closely related to dolphins, but the shape of the nose and head and the coloration are sufficiently different to distinguish the two.

		The two parts of the nasal apparatus have joined at the external end to form a single opening.

		Whales are marine mammals which live their whole lives underwater.
		The scientific term cetacean is used to describe the 78 known species of whales dolphins and porpoises (order Cetacea) Cetaceans can be further divided into three suborders: the toothed whales or Odontoceti; baleen whales or Mysticeti; and extinct whales or Archaeoceti.
		ODONTOCETI — The toothed whale — All of the dolphins and porpoises and most of the smaller whales are toothed whales that feed primarily on fish and invertebrates like squid and crustaceans.

	The Remarkable Ocean World: The Library: And They Call Him Flipper...
		The separation of the cetaceans into two suborders, the Odontoceti, the toothed whales, and the Mysteceti, the baleen whales, represents an interesting evolutionary solution to the problem of getting food.
		The Odontoceti and Mysteceti also differ in another important way: the Odontoceti use echolocation to find their prey.
		Of the Odontoceti, the sperm whale is the largest, measuring close to 60 feet in length, and weighing from 32 to 45 tons.

	What is the difference between dolphins and porpoises?
		All cetaceans are completely aquatic mammals, have a streamlined body, a tail fluke, and a blowhole (which is what these air-breathing animals use to breathe).
		The dolphins and porpoises are also classified in the scientific suborder, Odontoceti, which are the toothed whales.
		All odontocetes also have the ability to echolocate, the ability to detect objects in their underwater environment using the echoes of a sound, much like sonar.

		Included within Odontoceti are the dolphins and porpoises.
		The most obvious difference is the presence of teeth in all Odontoceti species, while other differences include a single blowhole and an asymmetrical skull.
		While generally thought to be whales, they are actually members of the dolphin family (Dephinidae).

	Whales
		If the new baby has trouble swimming the mother whale often helps lift her baby to the surface by getting under it and pushing the baby to the surface.
		Odontoceti whales, on the other hand, have to chase their prey, and they eat bigger animals one at a time.
		Odontoceti whales are referred to as "toothed whales".

		The mammalian order of Cetacea is divided into two sub-orders: the mysticeti, or baleen whales, and odontoceti, or toothed whales.
		Not coincidentally, all the species commonly referred to as "small cetaceans" are odontoceti.
		Not that all mysticeti are large and all odontoceti are small: the Baird's beaked whale is larger than the minke whale (Balaenoptera acutorostrata); the sperm whale (Physeter macrocephalus), the largest odontocete, dwarfs the smallest mysticete, the pygmy right whale (Caperea marginata).

	Phylogeny revisited (Site not responding. Last check: 2007-10-20)
		Some recent analyses of three mitochondrial DNA regions suggest that sperm whales are the sister group to baleen whales and, therefore, the suborder Odontoceti (toothed whales) constitutes a paraphyletic group.
		I cladistically analyzed the available morphological data, including that from relevant fossil taxa, for all families of extant cetaceans to test this hypothesis.
		All synapomorphies that support the Odontoceti node are decisive, not related to the evolution of highly correlated characters, and provide the same result regardless of what order mammals is used as an outgroup.

	Are dolphins considered whales? - ask Dr. Galapagos
		These dolphins belong to the suborder Odontoceti, which means they are "toothed whales".
		Other toothed whales include sperm whales (the biggest), beaked whales, bottlenose whales, porpoises, beluga whales, narwhals, river dolphins, pygmy sperm whales, and dwarf sperm whales.
		And sometimes the same people who say, or at least imply, that dolphins and porpoises are not whales will turn right around and tell you that dolphins are members of the "toothed whale" club (club is not an official science word), or more correctly, the suborder "Odontoceti".
