One of SeaWorld’s better-known orcas, Tilikum, perhaps best known for killing his trainer in 2010, died early Friday morning. Tilikum was interacting with his trainer, 40-year-old Dawn Brancheau, at SeaWorld Orlando’s Shamu Stadium when he grabbed her by the ponytail and pulled her underwater as a horrified audience looked on.
The incident sparked a backlash against SeaWorld and inspired the movie “Blackfish,” which questioned the ethics of orcas in captivity.
SeaWorld said he died surrounded by trainers, care staff and veterinarians. A cause of death is yet to be determined and a necropsy is planned. However, the organization said he had faced “very serious health issues” and veterinarians had been treating him for a “persistent and complicated bacterial lung infection.”
Tilikum, SeaWorld said, was estimated to be 36 years old, a little older than the orcas, commonly known as “killer whales,” who live in the region where he originated. He came to SeaWorld in 1991 from Sealand of the Pacific in Canada.
SeaWorld recognized Brancheau in a blog post about Tilikum, saying the killer whale will be “inextricably connected” to her death. After the incident, SeaWorld continued to allow Tilikum, who weighed 12,000 pounds, to mix and mate with the rest of the orcas.
