Editing Common dolphin (section)

===Captivity===

Common dolphins are not common in captivity. But on at least three occasions, a beached common dolphin in California was nursed back to health at [[SeaWorld San Diego]], but deemed unfit to release back to the ocean. These common dolphins remained at SeaWorld with the bottlenose dolphin exhibit. On one occasion, a male common dolphin managed to impregnate one of the female bottlenose dolphins in the exhibit, leading to four hybrid births.<ref name="hybrid">{{cite journal|title=Captive-born bottlenose dolphin × common dolphin (''Tursiops truncatus'' × ''Delphinus capensis'') intergeneric hybrids|author1=Zornetzer H.R. |author2=Duffield D.A. |journal=Canadian Journal of Zoology |volume=81 |issue=10 |pages=1755–1762 |date=October 1, 2003|doi=10.1139/z03-150|bibcode=2003CaJZ...81.1755Z }}</ref> One of the resulting common dolphin/bottlenose dolphin hybrids remained at SeaWorld, San Diego (alternately under the name Cindy or Bullet) while the other (named CJ) was kept at [[Discovery Cove]], and was moved to SeaWorld Orlando in 2016.

Other than at SeaWorld, at least 90 common dolphins are known to have been captured from the wild and kept in captivity. Captured common dolphins are said to be difficult to keep in captivity.<ref name="TheCommon" />

The behavior of captive common dolphins is not very well studied. However, a study was conducted in New Zealand of common dolphin reacting to swimmers at [[Marineland of New Zealand|Marineland]].<ref>{{Cite journal |date=2003 |title=Behavioural responses of captive common dolphins Delphinus delphis to a 'Swim-with-Dolphin' programme |journal=Applied Animal Behaviour Science}}</ref> Unlike bottlenose dolphins (which demonstrated antagonistic or sexual behaviors), the common dolphins retreated to the refuge center of the pool, where swimmers were not allowed. They did not leave the refuge section until the swimmers left. The dolphins also surfaced much more frequently, which is a possible indicator of stress. Aggressive and playful behavior among the dolphins decreased when swimmers were present. This behavior is consistent with wild common dolphins off of New Zealand, as they actively avoid swimmers.<ref>{{Cite journal|last=Kyngdon|first=D.|date=2003|title=Behavioural responses of captive common dolphins Delphinus delphis to a 'Swim-with-Dolphin' programme.|journal=Applied Animal Behaviour Science|volume=81|issue=2|pages=163–170|doi=10.1016/S0168-1591(02)00255-1}}</ref>
