Some snakes can stay alive even an hour after having their head removed from their body! One example is the cobra snake which recently became known worldwide for killing a cook 20 minutes after its head was cut off.
Fan Peng was cooking a cobra soup, a delicacy in Asia, when he was bitten by the reptile. The cook was heading towards the garbage bin to throw away the serpent’s severed head when the cobra bit him-injecting him with its fast acting venom. Customers heard him scream and called an ambulance. Unfortunately, paramedics administered the antivenin too late for the cook to be saved.
