These venomous snakes have short fangs and strike down, then chew, when they attack. They have rings of color in a repeating black, yellow, red, yellow pattern. Some harmless snakes have colors like that, but their red and yellow rings don’t touch. Remember this saying: "Red on yellow, kill a fellow. Red on black, venom lack." They’re found in woody, sandy, or marshy areas of the southern U.S.
