For the last 37 years, an orca named Kiska has been living in a narrow concrete pool at Marineland in Ontario, Canada, far from the open waters of the Northern Atlantic where she was captured as a calf.
Throughout most of her life in captivity, she was made to perform in front of crowds and to produce offspring, five in all, but each of whom failed to survive long into maturity. She's had numerous companions with which to share her existence, though over decades they have all departed, either through transfers to other marine parks, like Seaworld, or in death.
Today, Kiska is alone, prompting some to call her the "world's loneliest orca". She no longer performs, but is still one of the park's headline attractions.
At around age 40, Kiska is by no means a young killer whale, but she's far from exceeding the lifespan seen in her counterparts in the wild -- though one might not guess that from looking at her. Killer whale advocacy groups, like Orca United and Ontario Captivity Animal Watch (OCAW) have raised the alarm that Kiska's body is showing serious signs of failing health.
