Called the death barrel roll or gator roll...

The one thing about catching big fish is how I can be impressed at how wiley some of these large fish are. Now I'm not talking about the bullhead confusion roll. I'm talking about that rare encounter of how a Musky does that death barrel roll or gator roll often on the strike that's near boatside or coming close to shore for the shore fisherperson. Many of time it leads to snapping the line. Now I've also encounter this with a flathead catfish as well as a channel catfish.
