The African spitting cobras, Naja pallida, Naja nigricollis, defend themselves by squirting their venom in the eyes of a potential aggressor. While propelling the poison with high velocity from their teeth, the snakes toss their head in a circular or shaking movement. High-speed shots analyze the motion, which only takes about 50 ms. Experiments with different face-dummies show the strategy of this defence behaviour.
