Chicago's Shedd Aquarium is struggling to stabilize several beluga whales recently transferred from Marineland in Niagara Falls. Following the deaths of two whales in less than two weeks, the facility is providing 24-hour monitoring for the remaining animals.

The deaths of Peekachu and Rain

Shedd Aquarium reported that the health of the transferred whales is currently unstable, with none of the animals meeting the facility's health standards. This crisis follows the recent deaths of two Marineland belugas: 20-year-old Rain and a whale named Peekachu, who died on August 25, just two weeks after arriving in Chicago.

The loss of these whales was compounded by the death of a 34-year-old beluga that had been a long-term resident at the Shedd Aquarium. According to Shedd Aquarium, staff are currently monitoring hydration, breathing rates, and social interaction patterns as they attempt to manage the fluctuating conditions of the surviving whales.

A history of mortality from Marineland to Mystic Aquarium

This relocation follows a period of instability for Marineland, a Niagara Falls theme park that recently closed after facing financial exhaustion. The movement of these animals mirrors a previous transfer in 2021, when five whales were moved to Mystic Aquarium in Connecticut, where two died within a year and a third died two years later.

While Mystic Aquarium stated those whales had pre-existing conditions, Marineland maintained they were healthy upon departure. This pattern of mortality is part of a larger, troubling statistic for the Niagara Falls site, which saw nineteen belugas, one killer whale, and one dolphin die between 2019 and 2025.

The discrepancy between Marineland's health claims and Shedd's clinical findings

A significant point of contention exists regarding the physical condition of the whales prior to their move. As the report indicates, the Marineland belugas were reportedly given a clean bill of health in the days leading up to their relocation. However, Shedd Aquarium has noted that several whales are presenting clinical concerns, such as irregular eating habits and inconsistent hydration.

Several questions remain regarding the exact cause of death for the whales and whether the remaining belugas at Shedd Aquarium can be stabilized.. while Shedd Aquarium is monitoring breathing rates and social interaction, the facility has not yet confirmed if the clinical concerns are due to the stress of transport or pre-existing conditions from Marineland. The aquarium is currently awaiting lab results to provide definitive answers.

The end of Canadian whale captivity via a 34-animal move

The transfer of these whales is part of the largest collective move of captive whales in history, involving 30 belugas and four dolphins sent to five different aquariums in the United States and Spain. This massive operation, which received final approval from Fisheries Minister Joanne Thompson , effectively marks the end of whale captivity in Canada.

The final stage of this move included the transport of a beluga named Tofino, described by trainer Taylor-Lee Dell as the last whale in captivity in Canada. Tofino was loaded onto a truck in Niagara Falls on August 31 and transported to Chicago, marking the conclusion of a controversial period that included threats from Marineland to euthanize the animals if emergency funding was not provided.
