Shedd Aquarium Announces Death of Fourth Beluga Following Rapid Health Decline

Osiris was among 30 belugas rescued from Marineland in Niagara Falls, Ontario, after caretakers at the shuttered park had threatened to euthanize the whales.
Shedd received nine rescued belugas over several months, more than doubling the aquarium’s existing pod; Osiris was part of the first group of four arrivals in mid-July.
Before her death, Osiris had shown signs of dehydration and an electrolyte imbalance. Her appetite and social behavior improved after she received fluids and medication, although the aquarium cautioned that her progress was not linear.
Another rescued beluga, Jelly Bean, died after being transferred from Canada to Oceanogràfic Valencia in Spain, underscoring that losses have occurred among the broader international rescue effort beyond Shedd Aquarium.
Osiris, a 26-year-old female beluga rescued from a shuttered Canadian marine park, has died at Chicago's Shedd Aquarium after sudden health problems and rapid decline. Edmonton Sun reported that Osiris arrived in July as part of a group of rescued whales and struggled with dehydration and electrolyte imbalance, despite receiving fluids and medication.
Her death marks the fourth beluga lost at Shedd and the third rescued whale to die there. Calgary Sun noted that Osiris was among 30 belugas rescued from Marineland in Niagara Falls, Ontario, after staff threatened to euthanize them when the park closed. The aquarium will perform a necropsy while caring for the remaining rescued whales.
Thirty belugas needed homes when Marineland shut down in Niagara Falls, Ontario. Daily News explained that Shedd Aquarium received nine of them over several months, more than doubling its existing pod. Osiris arrived in July as part of the first group of four rescued whales, joining a facility working to rehabilitate whales removed from captivity.
After arriving at Shedd, Osiris developed serious health problems. Press Democrat reported that the 26-year-old beluga faced dehydration and electrolyte imbalance. Staff gave her fluids and medicine, and her appetite and social behavior improved at times. However, the aquarium warned that her progress was not steady, and her condition deteriorated rapidly before her death.
Osiris is the third rescued beluga to die at Shedd, Twin Cities confirmed. Two other rescued whales—Peekachu and Rain—died before her. The aquarium also lost Beethoven, a longtime resident. Each death has prompted investigations, with necropsies and analyses still pending from previous cases. The losses extend beyond Chicago. Another rescued beluga named Jelly Bean died after transfer to Oceanogràfic Valencia in Spain, showing that challenges affect the broader international rescue effort.
Shedd staff are providing round-the-clock care to the remaining rescued belugas. Each whale receives individualized attention based on complex medical histories. The aquarium continues monitoring their health and adjusting treatment as needed. Shedd's commitment to the surviving whales reflects the challenges of rehabilitating animals removed from captive conditions and preparing them for potential future environments.
