The short version
- The transfer of thirty belugas and four dolphins from Marineland marked the end of captive whale breeding in Canada, but five whales and one dolphin have since died at their new facilities.
- Necropsies revealed chronic diseases and ingested foreign objects in some deceased animals, though experts note it is too early to determine if deaths resulted from transport stress or pre-existing conditions.
- Animal welfare advocates argue that repurposing Marineland as a hospice or accelerating the construction of a seaside sanctuary would have been safer alternatives for animals unable to survive in the wild.
The international effort to relocate thirty beluga whales and four dolphins from Canada’s shuttered Marineland park has concluded with mixed results. While the operation successfully moved the last captive cetaceans out of the country, fulfilling a long-standing goal for animal rights advocates, it has also been marred by significant mortality. Five of the transferred belugas and one dolphin have died since arriving at their new homes in the United States and Spain.
The deaths occurred across multiple facilities involved in the rescue. Chicago’s Shedd Aquarium reported the loss of four belugas: Peekachu, Rain, Orisis, and Caspian. Additionally, Beethoven, a long-time resident of Shedd who was not part of the Marineland transfer but died around the same time, passed away after eight new whales arrived. In Valencia, Spain, Europe’s largest aquarium, Oceanogràfic València, recorded the deaths of one beluga named Jelly Bean and one dolphin named Echo.
Medical examinations of the deceased animals have provided some clarity on their final conditions, though not all causes are fully understood. Necropsies at Shedd Aquarium identified chronic inflammatory disease in the gastrointestinal systems of Peekachu and Rain. Investigators also found foreign objects in their stomachs, including feathers, large rocks, and paint flecks. Aquarium officials believe these items were ingested before the animals left Marineland, suggesting long-standing behavioral issues or environmental stressors at the former park.
Other health complications emerged during the transition. Preliminary examinations of Orisis indicated chronic liver disease. The dolphin Echo, who arrived with serious vision problems and other health issues, began experiencing difficulties swallowing and respiratory distress in the hours before her death. These findings highlight the complex medical histories of animals that spent decades in captivity.
The relocation effort was triggered when the Canadian government rejected Marineland’s plan to sell its whales to China due to animal welfare concerns. Facing no viable export options, the park initially stated the animals would need to be euthanized. This decision spurred a massive international rescue operation this summer, involving transport to Chicago, Atlanta, San Diego, San Antonio, and Valencia. Photographer Carlos Osorio documented the final departure of Tofino, the last captive whale in Canada, noting the emotional weight of ending an era that began with the park’s opening in 1961.
Experts caution against drawing definitive conclusions about the success or failure of the rescue based solely on these early deaths. The animals were facing euthanasia and had lived in an aging facility for years. According to a tally by the Canadian Press, approximately twenty whales died at Marineland between 2019 and September 2025. Shedd Aquarium acknowledged that some belugas likely had substantial, longstanding medical needs that pre-dated their arrival. Assessments before the move could not reveal every underlying condition or predict how each whale would respond to the stress of transition.
Despite the losses, aquarium officials report positive signs among the surviving animals. The remaining rescued belugas are eating well and receiving specialized care. Shedd emphasized that the rescue offered a path for continued medical attention that was not available at Marineland. However, the mortality rate has drawn criticism from some animal welfare organizations who question whether transport was the safest option for frail animals.
Melissa Matlow of World Animal Protection Canada expressed concerns about moving animals that may not have been healthy enough to withstand transport stress. Her organization had suggested alternative plans, such as repurposing Marineland into a hospice-style facility or fast-tracking the development of the Whale Sanctuary Project in Nova Scotia. Lori Marino, a neuroscientist behind the sanctuary project, argues that providing ocean-based sanctuaries would allow whales to regain autonomy while receiving care.
The situation underscores a broader global challenge regarding captive cetaceans. Worldwide, there are approximately 3,600 captive whales, dolphins, and porpoises, with few alternatives for those raised in captivity who lack survival skills for the wild. As countries like France and Mexico move to ban or restrict cetacean captivity, the question of how to care for existing populations remains unresolved. The Whale Sanctuary Project, which began construction recently after a decade of planning, aims to house twelve to fifteen whales, but fundraising continues as it seeks to become a viable long-term solution.
The closure of Marineland in 2024 followed years of financial woes and public backlash over animal welfare practices. With Canada banning cetacean captivity and breeding seven years ago, the departure of Tofino marked the end of an era. While the rescue operation prevented immediate euthanasia, the subsequent deaths highlight the difficulties of managing aging marine mammals in transition. The coming months will be critical in determining whether the surviving animals can thrive in their new environments or if further losses will occur.
