The following is a list of currently existing (or, in the jargon of taxonomy) 'extant' species of the infraorder cetacea (for extinct cetacean species, see the list of extinct cetaceans). The list is organized taxonomically into parvorders, superfamilies when applicable, families, subfamilies when applicable, genus, and then species.
Cetacea (/ s ɪ ˈ t eɪ ʃ ə /; from Latin cetus 'whale', from Ancient Greek κῆτος () 'huge fish, sea monster') [3] is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises.
The sperm whale or cachalot (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator.It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.
It is the cetacean with the greatest appetite for human interaction and the most commonly used dolphin in dolphinariums. [31] Although the Bottlenose dolphin is the most abundant cetacean species in the Mediterranean, its population is in a slight decline. [32] It can be found along the coasts of the entire basin. [17]

Researchers studying the mammal couldn’t confirm if the species went extinct. Then in 2010, two whole spade-toothed whales, both dead, washed up on a New Zealand beach.
Articles on almost every species have been started. Most species have their own article with the exception of mesoplodont whales (too little information known for separate articles) and humpback dolphins (the lack of consensus from the taxonomists makes difficult to know what species to choose). Better to do at the genus level to avoid passing ...
This list currently includes only fossil genera and species. However, the Atlantic population of gray whales ( Eschrichtius robustus ) became extinct in the 18th century, and the baiji (or Chinese river dolphin, Lipotes vexillifer ) was declared " functionally extinct " after an expedition in late 2006 failed to find any in the Yangtze River .
