A Beluga Died Days After Leaving Marineland. 

Peekachu, a 23-year-old female beluga, died Tuesday evening at Chicago’s Shedd Aquarium, roughly two weeks after arriving from the shuttered Marineland park in Ontario. Caretakers had noticed she was not consistently finishing her diet in the days before. Blood work indicated dehydration. As the animal care team worked through the evening to administer fluids and medicine, she died.

Shedd Aquarium has said a full necropsy is underway and that it will share the results once available. That is the headline, and it is the part of this story most outlets have led with.

Peekachu was one of 30 belugas that Marineland had continued to house after the park closed to the public in 2024, following the deaths of its owners and a collapse in its ticket revenue. As reported here previously, that closure set off an eight-month standoff between Marineland, Canadian regulators and a coalition of accredited U.S. and European aquariums over what would happen to the animals left behind. Ontario’s own compliance record on the facility, four outstanding orders covering water quality, equipment maintenance, record-keeping and enclosure conditions, was part of what made continued operation untenable. Marineland told federal officials the choice was export or euthanasia. Fisheries Minister Joanne Thompson used nearly that exact language in a letter to the company.

That standoff is also where the more sobering set of numbers comes from. According to provincial data obtained through freedom-of-information requests, 19 belugas and one killer whale died at Marineland between 2019 and this year, a toll of 20 animals in roughly six years. That is the baseline this rescue was measured against, not a hypothetical worst case, but a documented one, tracked by regulators, at the facility these whales were being moved out of.

Peekachu’s own circumstances add another layer. She was blind in one eye, among the smaller whales in her group, and had reportedly struggled to socialize before the move. Andrew Pulver, Shedd’s vice president of animal care, described her as adapting better than expected once she arrived, eating from caretakers and exploring her new habitat through the underwater viewing windows. He also stated plainly that her health could only be fully understood through ongoing assessment, given how long she had lived in her previous conditions. “We cannot emphasize enough that rescue is a step-by-step process for these whales, and that we truly are on a day-by-day basis in relation to their care and wellbeing,” he said in the aquarium’s statement.

That is a more honest description of what this operation actually is than “rescue” alone tends to convey. Moving 30 whales, several of them older, several with documented health limitations, out of a facility with a six-year mortality record of nearly three animals a year, was never a guarantee of a clean outcome for every individual. It was a bet that expert, round-the-clock veterinary care at accredited institutions gave each whale meaningfully better odds than staying at a park that had already lost two-thirds of its beluga population’s peers.

So far, that bet has largely held. Twelve belugas have reached SeaWorld’s facilities without incident. Eight, including Peekachu, went to Shedd. The remainder are en route or awaiting transport to Georgia Aquarium and Oceanogràfic València. One loss, in an animal already flagged as medically vulnerable before she ever left Canada, is a genuine tragedy for the team that cared for her. It is also, set against the number this same population was losing annually at its old address, a very different outcome than the one Marineland’s own mortality data would have predicted for a comparable stretch of time.

Shedd has said it will release the necropsy findings once complete. Until then, the more useful question may not be why Peekachu died, but what the record at her previous home suggests would likely have happened to her, and to the whales still waiting their turn, had nobody moved them at all.
