This harrowing footage shows a lonely killer whale circling its tank and thrashing water after surviving its friends and offspring.
Kiska, dubbed the ‘world’s loneliest orca’, circled the perimeter and splashes water over the walls of her isolated tank at MarineLand Park in Niagra Falls, Ontario, Canada.
She is said to have been captured in Icelandic waters in 1979, and has been in captivity ever since.
