Discussions of longevity can become surprisingly complex, and it is easy for people to be confused or misled. As we have seen, a careful look at the data supports the view that the survival rates of killer whales at SeaWorld are comparable to those of the wild.
This statement is incorrect, as I have demonstrated above.

 For a more comprehensive and technical look at the complexity of this subject, see van der Toorn, "Survival Guide to Survival Rates," Marine Mammals: Public Display and Research, 3(1) 27:38 (June 2000). The paper demonstrates the many pitfalls of comparing wild and captive populations, as well as invalid comparisons between "life expectancy" and "longevity." It recommended using survival rates instead.
