Two more beluga whales have died at Chicago's Shedd Aquarium, including one that was recently moved to the facility as part of a larger international effort to rescue the last remaining captive belugas in Canada. Rain, a 20-year-old female, was the second whale to die among a group of four that were transferred to Shedd in mid-August from a closed water park in Ontario. Another whale, Peekachu, died earlier in the week as caretakers worked to improve its health. A third whale, Beethoven, a 34-year-old male who had lived at Shedd for decades, also passed away. The aquarium has not yet disclosed the causes of these deaths, stating that necropsies, blood tests, and additional examinations are currently underway. Officials described the deaths as unexpected and said there is still much to learn about what led to them. The Shedd Aquarium took in 10 beluga whales as part of an effort to rescue 30 belugas and four dolphins from Marineland, a water park in Ontario that closed several years ago and was no longer able to properly care for its animals. On Tuesday, the aquarium announced the arrival of the last two of those 10 whales—two young males named Gimli and Yukon—from the Canadian park. According to provincial government data obtained through Freedom-of-Information laws and official statements, 20 whales—19 belugas and one killer whale—had died at Marineland since 2019. Shedd Aquarium officials previously told The Associated Press that the relocation of the belugas was a complex and carefully monitored process. The whales were transported using custom-made slings and temperature-controlled containers, and their health and behavior have been closely monitored on a minute-to-minute basis since their arrival. Canadian Minister of Fisheries Joanne Thompson expressed her sadness over Rain's death, stating that Canada's government has taken reasonable steps to ensure the safe rescue of the whales. She extended her thoughts to the care staff who worked tirelessly to support Rain and the other belugas. Other aquariums around the world are also helping to care for the rescued animals. The Georgia Aquarium, SeaWorld locations in San Diego and San Antonio, and Oceanogràfic Valencia in Spain are among the facilities taking in the belugas and dolphins from Marineland. The ongoing efforts highlight the international collaboration aimed at providing better care and living conditions for these animals.
