Heartbreaking timelapse footage shows Kshamenk, ‘the world’s lonliest orca,’ staring at the gate to his enclosure in Argentina for 24 hours. The killer whale has lived in the tiny concrete tank since 1992, and hasn’t seen another orca since his last tank mate Belen passed away in 2000. #orca #killerwhale #animals #heartbreaking #sad #tragic #argentina
