ORLANDO, Fla. — Tilikum the orca has died after more than two decades at SeaWorld Orlando, where he gained notoriety for killing a trainer in 2010 and was later profiled in a documentary that helped sway popular opinion against keeping killer whales in captivity.
He will not be replaced. He was the first of SeaWorld's orcas to die since the company announced the end of its orca breeding program in March 2016.
In a statement announcing Tilikum's death early Friday, SeaWorld officials said he had serious health issues including a persistent and complicated bacterial lung infection. Tilikum was estimated to be 36 years old. A necropsy will determine the cause of death.
The 2010 death of SeaWorld trainer Dawn Brancheau during a performance with Tilikum after a "Dine with Shamu" show shocked the public and changed the future of orcas at SeaWorld parks.
Brancheau was interacting with Tilikum before a live audience at SeaWorld Orlando when he pulled her from a platform by her arm and held her underwater. An autopsy report said Brancheau drowned but also suffered severe trauma, including multiple fractures.
Former SeaWorld orca trainer John Hargrove said Tilikum's death offered some closure in the violent death of his friend and colleague. But he said Tilikum also finally found relief.
"Tilikum has been sick, very sick, for so long, and after everything he's had to endure, this is to me like he's free," said Hargrove, who left SeaWorld in 2012 and was featured in the documentary "Blackfish."
"He lived a tortured existence in captivity. I think all the whales do, but if you had to pinpoint one of them, hands down I would say Tilikum."
