Two Indo-pacific bottlenose dolphins held at the Seoul Grand Park aquarium in South Korea are to be released back into the wild in July.
Geumdeung and Daepo, both male dolphins, were captured in a fishing net in 1997 and 1998 respectively and have spent nearly twenty years in captivity since.
It is believed the decision to release them came from the local mayor, Park Wan-soon. The dolphins will spend the next few months being prepared for their release.
Eventually they will be set free off the coast of Jeju island and will hopefully join up with the local population of around 100 other dolphins found in the area.
This would not be the first time dolphins have been released from captivity from South Korea. In 2013, three dolphins were returned to the wild after being illegally captured. Two of the dolphins were seen with calves in 2016.
