Can tiger sharks turn their stomachs inside out?

As in humans, indigestible items can be voided out the mouth. But, unlike ourselves, at least some sharks can evert the stomach at will: turning it inside-out through the mouth, rinsing the stomach lining in sea water, then retracting and returning it to the normal inside-in condition. Although no one has yet reported this behavior in the Great White, sharks can apparently do this all about as easily as you or I might return an inside-out sock to its correct topology.
