I've caught several Flatheads before with scars and bite marks on them. Caught this one Friday 7-10-09 and it had a bite mark on it across the top of its head and all the way back under its jaw almost to the opposite side of its head. No doubt it was a much bigger Flathead because it bit him and didnt let go right away. It had most of this ones head in its mouth. He went almost 40 lbs. Can't imagine the size of the other one. Sure would love to get that one on my hook.
