Dolphins and porpoises are kept in captivity. [[Bottlenose dolphin]]s are the most common, as they are relatively easy to train, have a long lifespan in captivity and have a friendly appearance. Bottlenose dolphins live in captivity across the world, though exact numbers are hard to determine. Other species kept in captivity are [[Atlantic spotted dolphin|spotted dolphins]], [[false killer whale]]s and [[common dolphin]]s, [[Commerson's dolphin]]s, as well as [[rough-toothed dolphin]]s, but all in much lower numbers. There are also fewer than ten [[pilot whale]]s, [[Amazon river dolphin]]s, [[Risso's dolphin]]s, [[spinner dolphin]]s, or [[tucuxi]] in captivity. Two unusual and rare [[hybrid (biology)|hybrid]] dolphins, known as [[wolphins]], are kept at [[Sea Life Park]] in [[Hawaii]], which is a cross between a bottlenose dolphin and a [[false killer whale]]. Also, two [[Common dolphin|common]]/bottlenose hybrids reside in captivity at [[Discovery Cove]] and [[SeaWorld San Diego]].{{citation needed|date=October 2024}}

In repeated attempts in the 1960s and 1970s, [[narwhal]]s kept in captivity died within months. A breeding pair of [[pygmy right whale]]s were retained in a netted area. They were eventually released in South Africa. In 1971, SeaWorld captured a California gray whale calf in Mexico at [[Ojo de Liebre Lagoon|Scammon's Lagoon]]. The calf, later named Gigi, was separated from her mother using a form of lasso attached to her flukes. Gigi was displayed at [[SeaWorld San Diego]] for a year. She was then released with a radio beacon affixed to her back; however, contact was lost after three weeks. Gigi was the first captive baleen whale. JJ, another [[gray whale]] calf, was kept at [[SeaWorld San Diego]]. JJ was an orphaned calf that beached itself in April 1997 and was transported two miles to SeaWorld. The {{convert|680|kg|lbs}} calf was a popular attraction and behaved normally, despite separation from his mother. A year later, the then {{convert|8,164.7|kg|lbs}} whale though smaller than average, was too big to keep in captivity, and was released on April 1, 1998. A captive [[Amazon river dolphin]] housed at [[Acuario de Valencia]] is the only trained [[river dolphin]] in captivity.<ref name="Whales">{{cite book|url=https://portals.iucn.org/library/sites/library/files/documents/RD-1991-001.pdf |archive-url=https://web.archive.org/web/20150509184324/https://portals.iucn.org/library/sites/library/files/documents/RD-1991-001.pdf |archive-date=2015-05-09 |url-status=live|last1=Klinowska|first1=Margaret|last2=Cooke|first2=Justin|year=1991| title=Dolphins, Porpoises, and Whales of the World: the IUCN Red Data Book|access-date=6 September 2015}}</ref><ref>{{cite journal| url=http://www.aquaticmammalsjournal.org/share/AquaticMammalsIssueArchives/2001/AquaticMammals_27-03/27-03_Goff.pdf |archive-url=https://web.archive.org/web/20151015214719/http://www.aquaticmammalsjournal.org/share/AquaticMammalsIssueArchives/2001/AquaticMammals_27-03/27-03_Goff.pdf |archive-date=2015-10-15 |url-status=live |title=Growth of two gray whale calves|author1=J.
