9/27/26 - Marineland Beluga Deaths: New Findings Raise Further Welfare Questions

Four belugas have died following this summer’s transfers from Marineland Canada. New medical findings reveal serious pre-existing illness in two whales, renewing questions about their care and the decisions surrounding their relocation.
At Chicago’s Shedd Aquarium, Peekachu, 23, died August 25; Rain, 20, died September 2; and Osiris, 26, died September 21. All three had arrived from the now-defunct Marineland over the summer.
On September 25, Shedd released preliminary findings showing chronic inflammation of the gastrointestinal tract in Peekachu and Rain—significant in Peekachu and severe in Rain. Veterinarians said the tissue changes indicated disease that likely developed months or years before their arrival. Shedd also found feathers, sticks, and large rocks in Peekachu’s stomach, believed to predate her transfer, and flecks of material that may be paint in Rain’s stomach. The aquarium said it did not believe these foreign materials directly caused their deaths.
The findings identify underlying illness but do not establish a definitive cause of death. Shedd reported no evidence of a shared infectious disease or environmental factor connecting Peekachu, Rain, and longtime resident Beethoven, whose examination showed age-associated changes. Beethoven was not part of the Marineland transfers. Osiris’s investigation remains separate and ongoing.
In Spain, former Marineland beluga Jelly Bean died at Oceanogràfic Valencia on September 17 after experiencing feeding difficulties. Her cause of death remains under investigation. The facility has since reported another loss: Echo, one of four dolphins transferred with the belugas, died September 23.
The transfers followed Marineland’s closure and warnings that it could no longer afford to care for the animals. This summer’s operation moved 30 belugas and four dolphins to aquariums in the United States and Spain. Participating institutions described the relocation as an urgent rescue, while acknowledging that some animals’ health histories were not fully understood. The latest findings make transparency about those assessments and decisions especially important.
CWI advocated for a different long-term future. In an October 2025 action alert, we urged Ontario Premier Doug Ford to help secure sanctuary retirement for Marineland’s remaining belugas through cooperation among government, nonprofits, and businesses. We recognized that no operating sanctuary could accommodate them all and called for developing an alternative while protecting their immediate welfare.
Earlier transfers also warrant attention. Of five Marineland belugas moved to Mystic Aquarium in 2021, three died by the end of 2023. NOAA attributed those deaths to severe intestinal disease and a rare metabolic disorder, and concluded that research activities had not caused them. Those findings concern different whales and cannot explain this summer’s deaths, but they underscore the importance of careful health assessments and continued scrutiny.
CWI calls for public findings on the deaths, independent veterinary scrutiny, and clear explanations of what is being done to protect the surviving animals. The evidence does not establish that transport caused these deaths; it does demand a fuller accounting of the whales’ health before and after relocation.
Their future must extend beyond moving between tanks. Governments and the captivity industry should invest in credible retirement options and prevent another generation from being bred into captivity. Protecting these animals means planning for their lifelong welfare before the next closure becomes an emergency.
