SeaWorld's Deadly Whale May Be Dying

(RTTNews) - SeaWorld Entertainment Inc. (SEAS) says the health of Tilikum, one of the most popular killer whale in the park, is deteriorating.

In its blog, Seaworld says: "Tilikum's behavior has become increasingly lethargic, and the SeaWorld veterinary and animal care teams are concerned that his health is beginning to deteriorate."

"It has been our duty and passion to make sure we give him the utmost care we possibly can," said Daniel Richardville, Animal Training Supervisor.

SeaWorld's business has come under fire since the critical 2013 documentary 'Blackfish,' which was about Tilikum. The orca had dragged a trainer named Dawn Brancheau under the water to her death in his tank at the Orlando park. He also killed trainer at the now-defunct Sealand of the Pacific in British Columbia and a man trespassing on SeaWorld Orlando's property.

The documentary claims killer whales exhibit increased aggression during captivity. Among other problems, the whales are said to have shorter life spans. The film severely affected the aquatic amusement park's attendance and revenues.
