Rescued beluga whale Peekachu dies suddenly at Shedd Aquarium following international relocation effort.

The eight belugas rescued by Shedd came in two waves: four arrived in late July and joined by a second group of four around Aug. 13, bringing the total rescued belugas at Shedd to eight and placing the aquarium on track to host 16 belugas in total.
The broader relocation effort to rehome Marineland belugas includes moving animals to facilities in Atlanta, San Antonio, San Diego, and Spain, as part of relocating up to 30 whales.
Marineland in Ontario closed to the public in 2024 due to financial difficulties, with officials warning they might euthanize the whales if permanent homes couldn’t be found.
Peekachu was described as blind in one eye and among the smaller belugas, yet she socialized well and explored her new habitat despite the impairment.
Belugas can be quite large, with the species capable of reaching up to about 15 feet in length and weighing as much as 3,300 pounds.
Peekachu, a 23-year-old beluga whale rescued from Marineland in Canada, has died at Chicago's Shedd Aquarium just weeks after arrival. Block Club Chicago reported that the female whale was one of eight belugas relocated to Shedd as part of a massive international rescue effort to rehome up to 30 whales from the shuttered Canadian park. Shedd staff had detected dehydration in Peekachu's bloodwork and provided medicine and fluids, but she died suddenly before recovering.
The beluga's death highlights the risks of relocating marine mammals across borders and between facilities. Chicago Tribune noted that Peekachu was blind in one eye but had socialized well with other whales in her new habitat. Shedd Aquarium has scheduled a necropsy to determine the cause of death and pledged to continue the broader rescue mission, which has already moved belugas to facilities in Atlanta, San Antonio, San Diego, and Spain.
Marineland in Ontario closed to the public in 2024 after financial troubles forced the decision. Global News reported that park officials warned they might euthanize the whales if permanent homes could not be found. The rescue operation became urgent: relocate up to 30 belugas to safety across North America and Europe before the park could no longer care for them.
Shedd Aquarium stepped up first, accepting two groups of belugas. Four arrived in late July, followed by a second group of four around August 13. This brought Shedd's total to eight belugas, with the aquarium on track to eventually host 16 whales total as part of the coordinated international effort.
When Peekachu arrived at Shedd, she showed promise despite her disability. Chicago Tribune described her as blind in one eye and smaller than other belugas, yet she interacted well with her new social group and actively explored her tank. Staff members believed she was adjusting to the dramatic change from captivity in a shuttered park to a major U.S. aquarium.
Bloodwork later revealed dehydration, a common threat to relocated marine mammals. Shedd veterinarians administered medicine and fluids to treat the condition. However, Peekachu died suddenly before showing signs of recovery. A necropsy is planned to clarify whether dehydration alone caused her death or if other underlying health issues contributed.
Peekachu's death has not stopped the rescue mission. Chek News reported that Canada's last captive dolphins have already left Marineland for a new home in Spain, while other belugas were transported to facilities in Atlanta, San Antonio, and San Diego. The coordinated effort involves dozens of staff members and specialized transport protocols to move whales safely across borders.
Shedd Aquarium has pledged transparency about the rescue's challenges and outcomes. The aquarium emphasized that relocating large marine mammals—belugas can reach 15 feet long and weigh up to 3,300 pounds—requires careful monitoring, gradual social integration, and ongoing veterinary care. Officials vowed to share updates as more information becomes available about Peekachu and the remaining relocated whales.
