Northern Water

that is the classic nerodia species threat display. here where i live there are no water mocosins in this county, but every good ol' boy say 'i killed ten water mocosins this year, when they are actual killing northern water snakes. they kill them because of this threat display. body flattened out and the head is flattened to give it a viper shape head. i think it is a cool mimic defense except that it has an opposite effect with people.
