Multiple rescued beluga whales die at Chicago’s Shedd Aquarium amid ongoing health investigations
By Drooid · · How we work
Core Event
Caspian, a 27-year-old female beluga rescued from the shuttered Marineland of Canada, died after several weeks of declining health and nearly four hours on life support. Her death marks the fifth rescued beluga to die at the Shedd Aquarium in recent months, following the earlier losses of Peekachu, Rain, Osiris and the resident whale Beethoven.
Background & Context
Marineland of Canada, located near Niagara Falls, Ontario, closed to the public in 2024 after financial difficulties. Facing the prospect of euthanizing its remaining cetaceans, the park arranged an international rescue that moved 30 belugas and four dolphins to aquariums in the United States and Spain over a six-week period in the summer of 2024. Ten of those belugas were transferred to the Shedd Aquarium, more than doubling the facility’s pod size.
Data & Statistics
- 30 belugas rescued from Marineland; 10 arrived at Shedd.
- Five rescued belugas have died at Shedd (Caspian, Peekachu, Rain, Osiris, and one earlier death not specified).
- One rescued beluga, Jelly Bean, died at Oceanogràfic in Valencia, Spain.
- Resident beluga Beethoven also died of age-related issues.
- Blood tests on Caspian revealed electrolyte abnormalities and dangerously acidic blood pH; necropsies on Peekachu and Rain identified chronic gastrointestinal disease; Osiris showed chronic liver disease.
Official Statements & Responses
Shedd Aquarium officials said Caspian’s condition had been a concern for weeks because she was eating less than her full diet, a critical issue for belugas that rely on food for hydration and nutrition. The aquarium’s veterinary team placed her on life support for several hours but could not reverse the decline. Shedd also emphasized that the six remaining rescued belugas are now eating their full diets and are being closely monitored.
Criticism & Opposition
Animal-rights advocates argue that the rescued whales were transferred before they were medically fit.
Conflicting Reports & Gaps
The aquarium’s necropsies have identified chronic gastrointestinal disease in Peekachu and Rain and chronic liver disease in Osiris, but officials have not linked these findings to a definitive cause of death for Caspian. No evidence of a shared infectious disease or environmental factor has been found, leaving the precise trigger for the recent fatalities unresolved.
Why It Matters
The series of deaths raises questions about the health screening and transport protocols used in large-scale marine mammal rescues. If chronic conditions were present before relocation, the rescue effort may have inadvertently exposed vulnerable animals to additional stress. The outcomes also affect public confidence in captive cetacean care and could influence future regulatory oversight of animal transfers between facilities.
Verbatim Quotes
- “Five dead belugas tells us that after years of neglect at Marineland, these whales were not healthy enough to withstand the stress of transport,” — Camille Labchuk, executive director of Animal Justice, a Toronto, Canada-based animal rights advocacy group
What’s Next
Shedd Aquarium officials indicated that additional necropsy results are pending and will be released when available. The institution plans to continue close monitoring of the six surviving rescued belugas, with particular attention to diet intake and overall health status.
