Tilikum Unchained | Tilly the Seaworld Killer Orca Whale Track

Tilikum (c. December 1981 – January 6, 2017), nicknamed Tilly,was a captive male orca who spent most of his life at SeaWorld Orlando in Florida. He was captured in Iceland in 1983; about a year later, he was transferred to Sealand of the Pacific in Victoria, British Columbia. He was subsequently transferred in 1992 to SeaWorld in Orlando, Florida, where he sired 21 calves throughout his life.

Tilikum was heavily featured in CNN Films' 2013 documentary Blackfish, which claims that orcas in captivity suffer psychological damage and become unnaturally aggressive. Tilikum was involved in the deaths of three people: Keltie Byrne, a trainer at the now-defunct Sealand of the Pacific; Daniel P. Dukes, a man trespassing in SeaWorld Orlando; and SeaWorld trainer Dawn Brancheau.
