Heartbreaking footage shows a captive killer whale lying almost motionless whilst staring at the gate to his enclosure for 24 hours straight in Argentina.<br /><br />Kshamenk, a 35-year-old Orca, is being held in a tiny pool at Mundo Marino, Argentina's largest aquarium.<br /><br />Shocked visitors have accused the park of holding the killer whale in cramped conditions with restricted movement and total isolation from its species. <br /><br />A 24-hour timelapse filmed by campaign group UrgentSeas on August 12 shows Kshamenk languishing motionless with his face pointed directly towards the enclosure's gate as if asking to be let out.<br /><br />Kshamenk - previously described as 'the world's loneliest Orca' - was first brought to Mundo Marino in 1992 after being captured off the Samborombón Bay on the coast of Buenos Aires. <br /><br />According to the aquarium, the then three-year-old orca was found beached on the bay by three fishermen along with three other killer whales.<br /><br />Kshamenk was then taken to his concrete tank at the aquarium, where he has spent the last 32 years.<br /><br />His tankmate Belen died in 2000, at the age of 13, meaning that he has reportedly spent the last 24 years in total isolation from his species.<br /><br />UrgentSeas, a non-profit organization advocating to end marine captivity, is campaigning to free Kshamenk and bring him to an open sanctuary with other orcas to socialize with. <br /><br />He is now the last remaining captive killer whale in Argentina.<br /><br />A spokesperson from the organization said: 'We continue to work with Argentinian activists and members of Congress to try to highlight and address his cruel world.<br /><br />'He needs to be removed from his tiny concrete tank and join other members of his species before it's too late.'<br /><br />MailOnline has contacted Mundo Marino for comment.
