Prison Life at Six Flags
The water quality in the walrus pool has been so poor that the walruses are “mostly blind,” and they have been malnourished. In 2015, Sivuqaq, one of the walruses, died at age 21 of heart failure. (According to the Alaska Department of Fish and Game, walruses can live up to 40 years.)
In January 2016, it was reported that Siku, a 22-year-old walrus at Six Flags, was suffering from a parasitic infection that caused “rivers of snot” so severe that she had become a mouth breather. The other walruses were also infected with parasites, although their cases were not as advanced as Siku's.
