After spending over four decades in a tank, Kiska, the last captive killer whale in Canada, has died at Marineland in Niagara Falls, Ontario. Kiska, also known as "the loneliest whale in the world," spent over a decade in isolation, displaying distressing behavior such as banging her head and gnawing her teeth on the pool's concrete walls. National animal law organization Animal Justice is urging provincial authorities to release the post-mortem results and prosecute Marineland for the unlawful distress Kiska clearly experienced throughout her final years.
