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.
Porpoises range in size from the vaquita, at 1.4 metres (4 feet 7 inches) in length and 54 kilograms (119 pounds) in weight, to the Dall's porpoise, at 2.3 m (7 ft 7 in) and 220 kg (490 lb).

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.
Cetacean species articles can contain: a short introduction on the species, such as whether it is baleen or toothed; physical characteristics such as their birth and adult sizes and weights for both sexes, colour, callosities, fin placement, size and shape, and how one may distinguish between that and other species
