The largest killer whale at SeaWorld Orlando fell ill last week and was quarantined in the park's medical pool, though a spokesman said Thursday that the animal is better now.
SeaWorld trainers had moved the whale, the six-ton male Tilikum, into the park's medical pool for treatment. The whale's illness was first reported by the television station WKMG Local 6.
Tilikum is the whale that killed a SeaWorld Orlando trainer in February 2010. He has also been linked to two other human deaths, including the 1991 death of a Canadian killer whale trainer and the 1999 death of a man who sneaked into SeaWorld's killer-whale enclosure after the park had closed.
