Quick Summary

Preliminary necropsy findings show that two belugas, Peekachu and Rain, who died shortly after arriving at Shedd Aquarium in Chicago from a former Marineland facility, had chronic gastrointestinal disease. The whales were 23 and 20 years old respectively and arrived on August 13 as part of an operation to rehome 30 belugas and four dolphins to various aquariums internationally. Fisheries and Oceans Canada cited "unacceptable neglect" regarding the health of these whales prior to their relocation, noting that the disease had likely been present for a long time before they were moved.

Story summary

Osiris, a 26-year-old female beluga whale from Marineland in Niagara Falls, Ontario, died on Monday morning at Shedd Aquarium in Chicago. Osiris was one of ten belugas moved from Marineland to Shedd over the summer as part of the largest collective move of captive whales involving 30 belugas and four dolphins relocated to five aquariums across the US and Spain between July and September 2024. Since then, four beluga whales have died after being transferred, with Osiris being the fourth death at Shedd Aquarium alone. Despite receiving intensive care, including fluids and medications upon arrival, Osiris struggled with her appetite and health, leading to sudden changes in behavior and respiratory patterns before her death. The cause of death is still under investigation, but preliminary necropsies suggest chronic inflammatory disease that likely began while the whales were at Marineland.
