This is in fact true nice one inci!...hammer head sharks are shaped that way to widen thier ability to sweep the sea bottom detecting the electric signitures of animals hidden beneath the sand....Studies into the ability of blindfolded ppl to predict wether somebody was looking at them or not have shown results significantly above chance to suggest something odd is going on. As all animals humans use electricity within nerves to send signals within the body but little research has been done into the external effects of the bodies nerve pulses.
