On Jan. 8, Seaworld San Diego had it’s final killer whale show. Seaworld’s shows that highlight killer whales have struck controversy over the past few years, forcing them to make drastic changes to the structure of the show. However, Seaworld plans to replace the show with a more “natural” experience of the killer whales. The  intention of the  new show is to focus on educating audiences about the killer whales, instead of entertaining them with stunts that the whales do not typically perform in the wild.

SeaWorld’s big changes were prompted by the CNN sponsored documentary, Blackfish, released in July 2013. The documentary highlighted the treatment of killer whales in captivity and exposed SeaWorld by releasing information about the three human deaths that occurred in killer whale tanks. Blackfish, however, mainly focuses on the killer whale, Tilikum, from SeaWorld Florida who was captured at age 2 and was used as the main breeding whale. About 54% of SeaWorld’s whales contain Tilikum’s DNA.

Tilikum has received attention and notoriety from people all around the world for many reasons.  However, not all have to do with his breathtaking performances in shows at SeaWorld. He is responsible for the deaths of trainers, Keltie Byrne and Dawn Brancheau, as well as civilian Daniel P. Dukes, a man found in Tilikum’s tank after hours whose story is a mystery. These deaths raised concern in the media about the credibility of SeaWorld and similar marine life parks.

Concerns for the future of these whales were not only expressed by the media, but other SeaWorld trainers also expressed their concerns for working with the whales going forward. Following the death of trainer Dawn Brancheau, the Occupational Safety and Health Administration stated that trainers were no longer allowed to have direct contact with the animal and there should be a barrier in between the person and the whale.

Along with the deaths, the documentary touched on the malnourishment of the mammals, stating that whales are plagued with illnesses in captivity that are not found in the ocean. They shared that there was one specific case in which a whale had to get their stomach pumped from trying to eat their way out of their holding cell. SeaWorld, however, rebuked this statement by saying that the whales have better quality of life in captivity and tend to live as long, if not longer than whales in the wild. This information went viral. Using the power of social media, animal activists formed a campaign against SeaWorld titled “SeaWorld of Hurt,” once again forcing SeaWorld to make a change in treatment of the whales.
