Abstract Die in Afrika beheimateten Speikobras, Naja pallida, Naja nigricollis, spritzen ihr Gift zur Verteidigung einem potentiellen Feind in die Augen. Während die Schlangen das Gift mit hoher Geschwindigkeit aus ihren Fangzähnen herausschießen, bewegen sie den Kopf kreisend oder wippend hin und her. Hochgeschwindigkeitsaufnahmen zeigen den Vorgang, der meist nur 50 ms dauert. Versuche mit verschiedenen Gesichtsattrappen zeigen die Strategie dieses Verteidigungsverhaltens.
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.
