Yes, I know this firsthand. When I was a kid my dad used to butcher snapping turtles, and I've eaten more turtle legs than most people. The first thing he'd do (for obvious reasons) is cut off the head. After we were done cleaning the turtle, we'd pick the head up and make it bite things, like the edge of the picnic table where it would hang for a long time.

I don't recommend eating snapping turtle. Mom always had to cook it a special way in a cast iron pan, and even then I still never really acquired a taste for it. It definitely doesn't taste like chicken.
