Another key aspect of an orca's life -- which is missing in captivity -- is the ability to swim up to 100 miles per day. When Granny was spotted earlier this week, she had just finished an 800-mile trek from northern California along with her pod. According to animal welfare advocates, long-distance swimming is integral to orcas' psychological health and well-being; SeaWorld, however, has gone on record claiming that orcas do not need to swim hundreds of miles regularly, ostensibly to defend the parks' cruel practice of keeping massive, powerful orcas confined to cramped tanks.
Since Granny was first spotted (as early as the 1930s), she's believed to have mothered two calves, who in turn have had calves of their own. (One of her grandchildren, Canuck, reportedly died at the age of 4 after being captured and held at SeaWorld). As her pod has grown, Granny has kept up with them -- without being separated through human intervention -- and traveled astonishing distances with her pod annually. Orcas at SeaWorld are routinely separated from their pods, which has been known to cause huge mental and emotional strain and can prevent calves from developing normally.
