Snakes with ballistic strike secret: Why do Viper snakes strike with lightning speed, and human beings can’t escape the danger?

Vipers execute strikes in a mere 40-90 milliseconds, significantly faster than human visual or spinal reflexes. These ballistic, pre-programmed movements, powered by specialized muscles and hinged fangs, ensure venom delivery before prey can react. While this speed aids hunting and defense, it necessitates ambush strategies due to the lack of mid-motion adjustments.
