My apartment building is right on the edge of a river. One night some years ago, there was a pretty big storm. The next morning, I'm driving out of the complex, and I see what appears to be a big black plastic garbage bag being blown across the road by the wind. I looked again - it was a big ol' grandaddy turtle or tortoise or I don't know what! A neighbor was walking nearby, I don't know if he helped it find its way back to the river, but that thing was at least 2 feet across! Wow.
