Even a shark’s electrical ‘sixth sense’ may be tuned to attack

Imagine having superhuman hearing. You’re at a noisy, cocktail party and yet your ears can detect normally inaudible sounds. But, unlike normal hearing, each of these sounds causes your ears to react in the same way. There is no difference between the quietest and loudest movements. According to a new study, that may be how a shark’s electrosensing organ reacts when it detects teensy, tiny electrical fields emanating from nearby prey.
