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 2017 Siku, one of the walruses, died at age 23, and in 2015, Sivuqaq, died at age 21.
In response to the two walrus deaths, Six Flags posted this question and answer flip chart near the walrus enclosure:
According to the Alaska Department of Fish and Game and the Center for Biodiversity, the lifespan for a walrus is up to 40 years.
In January 2016, it was reported that Siku had suffered from a parasitic infection that caused “rivers of snot” so severe that she had become a mouth breather.
