The Marineland belugas were supposed to be a happy ending. Instead, six of the thirty whales moved out of Canada's shuttered Niagara Falls park have died in roughly two months, and the story is getting darker with each announcement.

What happened to the Marineland belugas

Marineland closed to the public in 2025 after Canada banned keeping whales and dolphins for entertainment. With the park saying it had run out of money, euthanasia was floated, and a consortium of aquariums under the Association of Zoos and Aquariums stepped in. According to Mongabay, sixteen whales went to SeaWorld in California and Texas, ten to Shedd Aquarium in Chicago, two to Georgia Aquarium, and two to Oceanogràfic València in Spain.

The transfers happened in July and August. The deaths started almost immediately after.

The timeline of losses

Shedd Aquarium has taken the biggest hit. Peekachu, a twenty-three-year-old female, died in late August, and Rain, twenty, followed in early September. Osiris, a female described as a whale of clinical concern, died on September twenty-first, and Caspian, twenty-seven, died on October seventh after refusing to eat her full diet and being placed on life support, according to Mongabay.

In Spain, nineteen-year-old Jelly Bean died in September, and a bottlenose dolphin named Echo that arrived with serious vision problems died days later. The newest loss came on October eighteenth, when SeaWorld San Diego announced that Cyprus, a nine-year-old male, had died. He stopped eating two days earlier, and an ultrasound showed his intestines were not working properly.

The Chicago Sun-Times notes that a fifth Shedd whale, Beethoven, a long-time resident rather than a Marineland arrival, also died in early September.

What the necropsies found

Shedd's reports paint a grim picture of the whales' health before the move. Per the BBC, necropsies found chronic inflammatory disease in the digestive systems of Peekachu and Rain, along with foreign objects in their stomachs, including feathers, large rocks and flecks that looked like paint. Shedd believes those items were swallowed before the whales ever left Canada.

Shedd's final report said Peekachu had age-related tissue changes, existing high blood pressure and lung scarring, while Rain had widespread inflammation. External experts concluded that underlying disease made both whales more vulnerable to cardiovascular stress. Osiris had chronic liver disease.

Shedd's CEO says this is not a crisis

Shedd CEO Bridget Coughlin pushed back hard in an interview reported by the Chicago Sun-Times and WBEZ, saying the deaths do not amount to a crisis. She defended the rescue and called it a travesty that animals and nature are being politicized. A Shedd spokesperson told Mongabay that each examination makes it clearer that the lost whales were made vulnerable by chronic and severe illness, and that belugas are very good at masking discomfort.

SeaWorld says its remaining whales are in stable health but that it is premature to say they are fully in the clear. Georgia Aquarium says its two males are adjusting well, and Shedd says its six survivors are eating full diets.

Why activists say this was predictable

Naomi Rose, a marine mammal biologist at the Animal Welfare Institute, told Mongabay that nobody involved was surprised, because the whales were not well after years of poor care. She said transporting sick animals is dangerous, but leaving them in place was more dangerous, calling the rescue the best of a bad job.

Others see a bigger lesson. World Animal Protection Canada argues the deaths show why keeping whales and dolphins for entertainment must be phased out worldwide. Advocates are also pressing the aquariums not to breed the survivors, since the US agreement with the National Oceanic and Atmospheric Administration does not explicitly forbid it, and the facilities have not categorically ruled it out.

What to watch next

Expect more necropsy results, more scrutiny of the transfer plan, and a louder debate about whether captive cetaceans belong in tanks at all. Canada already made its call in 2019. For the thirty animals that were the last in the country, the real test is whether the survivors thrive over the months it takes to settle into new homes.
