Marineland says it has euthanized a seven-year-old beluga whale after a long battle with several different medical conditions.
It is the 18th beluga to die at the Niagara Falls, Ont., tourist attraction since 2019. Three other belugas sold to a Connecticut aquarium in 2021 have since died. Kiska, the country's last remaining killer whale in captivity, died in April 2023. One dolphin, one harbour seal, one grey seal, two sea lions and two Magellanic penguins have also died at the park in the past five years.
