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.
The species has been recorded making the longest dive ever documented for any mammal, rendering its detection and the estimation of its abundance very difficult. [124] Its distribution is known mainly through strandings. [125] It is also one of the cetacean species most frequently found stranded in the North-Eastern Caribbean. [127]
Despite this trend, dolphinariums are still widespread in Europe, Japan and North America. The most common species of dolphin kept in dolphinariums is the bottlenose dolphin, as it is relatively easy to train and has a long lifespan in captivity.

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 .
Orca show at SeaWorld San Diego. Orcas, or killer whales, are large predatory cetaceans that were first captured live and displayed in exhibitions in the 1960s. They soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness in captivity and sheer size. [1]
