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.
Granny doesn't simply represent an impressive feat of nature; she embodies what's wrong with SeaWorld by being a living example of what's right in the wild. While it's true that most wild orcas don't live as long as Granny has, their lifespans are still dramatically longer than those of SeaWorld's whales (the NOAA estimates that wild female orcas, like Granny, live an average of 50 to 60 years). Their lives are also filled with much more swimming, exploration, variety and bonding with family -- in other words, their lives are likely filled with much more joy.
