Five beluga whales have died at Shedd Aquarium in less than two months, shrinking the beluga population by nearly a third

Five beluga whales died at Chicago's Shedd Aquarium between Aug. 25 and Oct. 20, 2026, reducing the aquarium's beluga population by nearly a third. Shedd Aquarium said the deaths involved animals ranging from a calf to older adults and did not share a single confirmed cause. CEO Bridget Coughlin said the aquarium does not consider the losses a crisis, while animal welfare advocates questioned whether the deaths point to problems with care or captivity. Shedd said it is conducting necropsies and working with outside veterinary specialists as it reviews each case.
